A Design Argument From the Cognitive Reliability of Our Senses: A Proof of Classical Theism?

You are out hiking and the trail becomes faint and hard to follow. You peer into the distance and see what appear to be three stacked rocks. Looking a bit farther, you see another such stack. Now you are confident which way the trail goes.

Your confidence is based on your taking the rock piles as more than merely natural formations. You take them as providing information about the trail's direction, which is to say that you take them as trail markers, as meaning something, as about something distinct from themselves, as exhibiting intentionality, to use a philosopher's term of art. The intentionality, of course, is derivative rather than intrinsic. It is not part of the presupposition on which your confidence rests that the cairns of themselves mean anything. Obviously they don't. But it is part of your presupposition that the cairns are physical embodiments of the intrinsic intentionality of a trail-blazer or trail-maintainer. Thus the presupposition is that an intelligent being designed the objects in question with a definite purpose, namely, to indicate the trail's direction.

(show)

Of course, the two rock piles might have come into existence via purely natural causes: a rainstorm might have dislodged some rocks with gravity plus other purely material factors accounting for their placement. Highly unlikely, but possible. This possibility shows that the appearance of design does not entail design. 

Nevertheless, your taking of the rock piles as trail markers presupposes (and thus entails) that they are designed. It would clearly be irrational for you to take the piles as evidence of the trail's direction while at the same time maintaining that their formation was purely accidental. And if you found out that they had come into being by chance due to an earthquake, say, you would cease interpreting them as meaning anything, as providing information about the trail. One must either take the cairns as meaningful and thus designed or as undesigned and hence meaningless. One cannot take them as both undesigned and meaningful. For their meaning -- 'the trail goes that-a-way' -- derives from a designer. Their intentionality is derivative, not intrinsic. 

Now consider our incredibly complex sense organs. We rely on them to provide information about the physical world. I rely on eyesight, for example, both to know that there is a trail and to discern some of its properties. I rely on hearing to inform me of the presence of a rattlesnake. I rely on my brain to draw inferences from what I see and hear, inferences that purport to be true of states of affairs external to my body. The visual apparatus (eye, optic nerves, visual cortex and all the rest) exhibits apparent design. It is as if the eyes were designed for the purpose of seeing. But the appearance of design is no proof of real design. And indeed, human beings with their sensory apparatus are supposed to have evolved by an unguided or 'blind' process of natural selection operating upon random mutations. If so, eye and brain are cosmic accidents.

But if this is the case, how can we rely on our senses to inform us about the physical world? If eye and brain are cosmic accidents, then we can no more rely on them to inform us about the physical world than we can rely on an accidental collocation of rocks to inform us about the direction of a trail.

As a matter of fact, we do rely on our senses. Our reliance may be mistaken in particular cases as when a twisted tree root appears as a snake. But in general our reliance on our senses for information about the world is justified. Our senses are thus reliable: they tend to produce true beliefs more often than not when functioning properly in their appropriate environments. We rely on our senses in mundane matters but also when we do science, and in particular when we do evolutionary biology. The problem is:

How is our reliance on our sense organs justified if they are the accidental and undesigned products of natural selection operating upon random mutations?

To put it in terms of rationality: How could it be rational to rely on our sense organs (and our cognitive apparatus generally) if evolutionary biology in its materialistic (Richard Dawkins, Daniel Dennett, et al.) guise provides a complete account of this cognitive apparatus? How could it be rational to affirm both that our cognitive faculties are reliable, AND that they are accidental products of blind evolutionary processes? It cannot be rational. I agree with Richard Taylor who writes:

. . . it would be irrational for one to say both that his sensory and cognitive faculties had a natural, non-purposeful origin and also that they reveal some truth with respect to something other than themselves, something that is not merely inferred from them. (Metaphysics, 3rd ed., Prentice-Hall 1983, p. 104)

The foregoing may be summed up in the following design argument:

1. It is rational to rely on our cognitive faculties to provide access to truths external to them.

2. It is rational to rely on our cognitive faculties only if they embody the purposes of an intelligent designer.

Therefore

3. Our cognitive faculties embody the purposes of an intelligent designer.

To resist this argument, the materialist must deny (2). But to deny (2) is to accept the rationality of believing both that our cognitive faculties arose by accident and that they produce reliable beliefs. It is to accept the rationality of something that, on the face of it, is irrational.  

The above is an impressive argument, wouldn't you say? Of course  it needs beefing up in various ways. For example, how can we be sure that there is exactly one intelligent designer and not several working in concert? If these worries can be allayed, the argument seems to establish the existence of an intelligent designer of such cognitively gifted animals as ourselves, not to mention the world in which the gifted animals are embedded. Many will be quick to identify this intelligent designer with the God of classical theism. Essential to classical theism as I am using the term is the idea that God is a personal being (tri-personal on normatively Christian accounts) who is transcendent of the physical universe which he creates and sustains in being, and is thus transcendent in the sense that he could just as well exist in his full perfection without having created anything.  

But I don't believe the above argument amounts to a proof of classical theism. It does not render the latter rationally inescapable; at best, it renders it rationally acceptable.  On classical theism, the intelligibility of nature has a transcendent source: it accrues to nature ab extra, which is to say: it is not immanent in nature. But why couldn't the intelligibility of nature, and with it, the cognitive reliability of the natural faculties with which we investigate nature, be inherent in the natural world?  The idea is not that 'Mother Nature' is a person with conscious purposes in the way that God is a person with conscious purposes, but that nature, below the level of conscious mind, is yet mind-like in that it aims at certain outcomes, and thus has 'purposes' in an analogous sense of the term. Dispositionality provides an analogy in the small for the immanent intentionality and teleology of nature in the large.

To say that a wine glass is fragile, for example, is to say that it is disposed to shatter if suitably struck or dropped onto a hard surface from a sufficient height. Several philosophers have noted the analogy with conscious intentionality.   A consciously  intentional state exhibits

a. directedness to an object;
b. an object that may or may nor exist;
c. an object that may be, and typically is, indeterminate or incomplete.

For example, right now I am gazing out my study window at Superstition Mountain. The gazing is an intentional state: it is of or about something, a definite something.  It takes an accusative, and does so necessarily. The accusative or intentional object in question presumably exists. But the intentional object is what it is whether or not it exists. The phenomenological description of object and act remains the same whether or not the object exists.  Moreover, the object as presented in the act of gazing is incomplete: there are properties such that the intentional object neither has them nor their complements. Thus, to a quick glance, what is given in the intentional experience is 'a purplish mountain.' Just that. Now anything purple or purplish is colored, and anything colored is extended; but being colored and being extended are not properties of the intentional object as such. No doubt they are properties of the mountain itself in reality; but they are not properties of the precise intentional object of my gazing, which has all and only the properties it is seen to have. Furthermore, in reality, yonder mountain is either such that someone is climbing on it or not; but the intentional object of my momentary gazing is indeterminate with respect to the property of being climbed on by someone.

The same or similar points can be made about dispositions. If a piece of glass is fragile, then it is disposed to shatter if suitably struck. There cannot be a disposition that is not a disposition to do something, to shatter, or explode, or melt.

Second, the reality of a disposition is independent of its manifestation: a fragile piece of glass is actually fragile whether or not it ever breaks. From the fact that x is disposed to F, one cannot infer that x ever Fs. This parallels a feature of intentionality: from the fact that x is thinking about Fs one cannot infer that there exist Fs that x is thinking about. (If I am thinking about unicorns it does not follow that there exist unicorns I am thinking about; if I want a sloop it doesn't follow that there is a sloop I want; if Ernest is hunting lions it doesn't follow that there are any lions he is hunting.)

Third, although a manifested disposition is a fully determinate state of affairs, this complete determinateness is not present in the disposition qua disposition. The disposition to shatter if suitably struck is not the disposition to shatter into ten pieces if suitably struck, although it is of course the disposition to shatter into some number or other of pieces, the exact number being left indeterminate.

Conclusion and Metaphilosophical Upshot

And so it might be like this: nature in itself is animated by an intrinsic immanent teleology or intentionality below the level of conscious mind, an intrinsic (as opposed to derivative) purposiveness which is present in nature all along, but which becomes conscious only in us. This intrinsic and ubiquitous pre-conscious teleology or purposiveness suffices to ground the cognitive reliability of our faculties, and in such a way as to make it rational for us to trust their deliverances.  For on this scheme, there is nothing fluky or accidental about mind. Mind is king and it is there all along. And this without any  assistance ab extra from God, and of course without any constructive 'worldmaking' nonsense of the Goodmanian sort. (Allusion to Nelson Goodman, Ways of Worldmaking). We also  avoid the eliminativist Unsinn of Daniel Dennett the scientistic sophist.

I am limning the metaphysical scheme presented by Thomas Nagel in his Mind and Cosmos, an overview of which you will find at my Substack site.

Nagel's panpsychist immanentism no doubt has it own flaws, as any decent aporetician ought to suspect.  But Nagel's proposal does challenge any quick acquiescence in the design argument for God sketched above.

And so I come around once again to my oft-made meta-philosophical claim that in these metaphysical and theological precincts (and not just here) there are no 'knock-down' arguments, no arguments that are rationally compelling (rationally coercive, rationally inescapable, philosophically dispositive, pick your favorite phrase).

Norms in Nature? Some Doubts

Substack latest. It opens like this:

Our friend Malcolm Pollack, riffing on some complaints of mine about Michael Anton's talk of natural rights, wrote the following:

Rights are normative in their essence, while Nature simply is. Therefore, I see only two possibilities:

1) “Natural” rights flow from an intrinsic source of normative authority. Since brute and indifferent Nature cannot be such a source, then for such rights to exist in themselves, as opposed to being mere conventions and intuitions, requires the existence of God. They are therefore “natural” rights in virtue of our nature qua creations of a transcendent and normatively authoritative Deity.

2) There is in fact no such authoritative source, and so natural rights are nonsense. (Upon stilts.) It may be in our nature to have the intuitions we do about possessing such rights, but it is a category error to imagine that rights themselves can originate in the material world.

In response, I pointed out that this is far too quick inasmuch as there are Aristotelians who seek to ground norms in nature herself. These thinkers do not accept what to Pollack and the modern mind seems self-evident, namely, that there is a gap between the normative and the factual that disallows any derivation of normative claims from factual ones.  One prominent Aristotelian is Philippa Foot. So let's see what she has to say.

David Berlinski on Evolution

Under three minutes.  Nice production job.

Related: David Gelernter, Giving Up Darwin.  Wasn't Gelernter one of the recipients of a Unabomber package?

Part of being an American conservative in my sense of the phrase is a commitment to the respectful but critical evaluation of whatever passes for orthodoxy in science, in religion, in philosophy, in literature and the arts, and wherever else.  Of course, that is not to say that the heterodox, as such, is credible.  In fact, being conservative, I am open to the notion that there is a  defeasible presumption in favor of the orthodox and traditional. If you have no idea what 'presumption' means, see Presumption and Suspension of Judgment. 

Note the adjective 'respectful'; it goes a long way toward distinguishing my type of critical stance from that of the leftist.

Giving Up Darwin

David Gelernter is always worth reading.

The Concept of Design

What is design and what does it imply?

Our starting point must be ordinary language. As David Stove points out, "it is a fact about the meaning of a common English word, that you cannot say that something was designed, without implying that it was intended; any more than you can say that a person was divorced, without implying that he or she was previously married." (Darwinian Fairytales, p. 190, emphasis added.) In other words, it is an analytic proposition that a designed object is one that was intended in the same way that it is an analytic proposition that a divorced person is one who was previously married. These are two conceptual truths, and anyone who uses designed object and divorced person in a way counter to these truths either does not understand these concepts or else has some serious explaining to do.

I should think that Richard Dawkins has some serious explaining to do. Consider the subtitle of The Blind Watchmaker. It reads: Why the evidence of evolution reveals a universe without design.

Now I think I understand that. What Dawkins will do in his book is argue how the modern theory of evolution shows that the natural universe as a whole and in its parts is in no way the embodiment of the intentions and purposes of any intelligent being. Thus a bat, a piece of "living machinery," is such that "the 'designer' is unconscious natural selection." (p. 37) The scare quotes show that Dawkins is not using 'designer' literally. What he is saying, putting the point in plain English, is that there is no designer. For if there were a designer, then he would be contradicting the subtitle of his book, which implies that no part of nature is designed. So far, so good.

Unfortunately, on the same page Dawkins says the following about Paley:

His hypothesis was that living watches were literally designed and built by a master watchmaker. Our modern hypothesis is that the job was done in gradual evolutionary stages by natural selection.

But now we have a contradiction. We were told a moment ago that there is no designer. But now we are being told that there is a designer. For if the design job is done by natural selection, then natural selection is the designer.

Now which is it? Is there a designer or isn't there one? What this contradiction shows is that Dawkins is using 'design' and cognates in an unintelligible way.

Some will say I am quibbling over words. But I am not. The issue is not about words but about the concepts those words are used to express. I am simply thinking clearly about the concepts that Dawkins et al. are deploying, concepts such as design.

If you tell me that design in nature is merely apparent, and that in reality nothing is designed and everything can be explained mechanistically or non-teleologically, then I understand that whether or not I agree with it. But if you tell me that there is design in nature but that the designer is natural selection, then I say that is nonsense, i.e. unintelligible.

One cannot have it both ways at once. One cannot make use of irreducibly teleological language while in the next breath implying that there is no teleology in nature. The problem is well expressed by Stove:

. . . ever since 1859, Darwinians have always owed their readers a translation manual that would 'cash' the teleological language which Darwinians avail themselves of without restraint in explaining particular adaptations, into the non-teleological language which their own theory of adaptation requires. But they have never paid, or even tried to pay, this debt. (DF 191)

A Look at Some Unintelligent Design Reasoning in Dawkins

Here is an old Powerblogs post from some years ago.  Still seems right to me.  A student in the area wants to discuss Dawkins and his New Atheist gang with me.  So I'm digging up and reviewing all my old Dawkins materials. The New Atheism is already  old hat.  A movement for cyberpunks and know-nothings.  The old atheism of J. L. Mackie et al. is respectable and I respect it.

.......................

Richard Dawkins and Jerry Coyne have a piece in The Guardian entitled One Side Can Be Wrong. I will quote a bit of it and try to determine what exactly the argument is, and whether it is cogent and tells against Intelligent Design. The link in the text is my interpolation.

(show)

Similarly, the claim that something - say the bacterial flagellum - is too complex to have evolved by natural selection is alleged, by a lamentably common but false syllogism, to support the "rival" intelligent design theory by default. This kind of default reasoning leaves completely open the possibility that, if the bacterial flagellum is too complex to have evolved, it might also be too complex to have been created. And indeed, a moment's thought shows that any God capable of creating a bacterial flagellum (to say nothing of a universe) would have to be a far more complex, and therefore statistically improbable, entity than the bacterial flagellum (or universe) itself - even more in need of an explanation than the object he is alleged to have created.

Observe first of all that there is a difference between what Dawkins and Coyne impute to the proponent of ID, namely, "the bacterial flagellum is too complex to have evolved" and what they should have imputed to him, namely, "the bacterial flagellum is too complex to have evolved by natural selection." The proponent of ID, as I understand the position, need not deny evolution construed as the fact of common descent with later forms of life arising from earlier ones by numerous successive and slight modifications. What the proponent of ID questions is the mechanism of this descent, namely, natural selection. The question is whether there are forms of organizational complexity that cannot be accounted for by natural selection.

Once this is appreciated, it is easy to see that if something is too complex to have evolved in one way, by natural selection, it does not follow that it is too complex to have evolved in another way, i.e., by being created by an intelligent designer.

Dawkins and Coyne, however, think that ID is involved in an error of reasoning. What the proponents of ID are doing is giving a circular explanation. To be explained is a complex entity, the bacterial flagellum say. But the entity invoked in the explanation is itself a complex entity. So complexity is being explained in terms of complexity -- which is circular. Thus they write,

If complex organisms demand an explanation, so does a complex designer. [. . .] the "default" logic of the creationists remains thoroughly rotten.

But this shows a complete misunderstanding of what the proponent of ID is doing. It would be circular to try to explain complexity in terms of complexity. But it is not circular to explain one form of complexity in terms of another. The complexity that needs to be explained is the complexity that seems to have been designed. To invoke a crude analogy, it is not the complexity of a pile of rocks that needs personal explanation, but the complexity of a cairn, a pile of rocks whose assembly shows that they mark the trail. Now I cannot account for a pile of rock's being a cairn by invoking natural processes; I need to invoke an intelligent designer, a person such as a trail-blazer or trail-maintainer. Of course, this person is even more complex than his product. But there is no circularity since material complexity is not being explained by material complexity but by the thoughts, intentions and actions of a person. Material complexity is being explained by personal complexity. Hence there is no circularity in the explanation.

It is also worth pointing out that if A explains B, the explanation can be good even if A remains unexplained. Why so many wildfires this year? Because of a profusion of brush which in turn was caused by unusual spring rainfall. If this is a good explanation, its goodness does not require an explanation of why there was an unusual amount of rainfall.

So as far as I can see the proponent of ID is not committing any logical error. Dawkins is simply mistaken to accuse the IDist of "thoroughly rotten" logic. Of course, the IDist is violating a rule of natural science, namely the rule that everything be accounted for naturalistically, i.e., in terms of the space-time system and the laws that govern it. Thus living processes must be explained using the same laws as govern nonliving processes. One is no longer playing the scientific game if one invokes irreducible mentality or irreducible vitality.

But to violate the rule I just mentioned is not to violate any logical rule.

And it's no solution to raise the theologian's plea that God (or the Intelligent Designer) is simply immune to the normal demands of scientific explanation. To do so would be to shoot yourself in the foot. You cannot have it both ways. Either ID belongs in the science classroom, in which case it must submit to the discipline required of a scientific hypothesis. Or it does not, in which case get it out of the science classroom and send it back into the church, where it belongs.

If natural science must play by the rule mentioned above to be natural science, then ID is not natural science. To invoke an irreducibly intelligent designer (whether or not identical to God as traditionally conceived) is to invoke something that is not a mere part of the space-time system. But it is equally true that naturalistic evolutionary biology is not strictly science either since it rests on philosophical assumptions that cannot be justified scientifically. Naturalism, the thesis that nothing (or perhaps nothing concrete) exists apart from the space-time system is a philosophical thesis. Cognate doctrines such as physicalism and scientism are also philosophical, not scientific doctrines strictly speaking. So I conclude as follows:

If ID should be removed from the science classroom and relocated in church, then Dawkins' evolutionary biology should also be removed from the science classroom and relocated in the philosophy lecture hall. For neither is science strictly speaking. But before Dawkins is allowed in the philosophy lecture hall he must take some logic courses. (You will have noticed above how refers to a syllogism as false -- that is logically inept.)

The Dawkins Hustle

Karl White sends us to this Spectator article and provides this summary:

For $85 a month, you get discounts on his merchandise, and the chance to meet ‘Richard Dawkins Foundation for Reason and Science personalities’. Obviously that’s not enough to meet the man himself. For that you pay $210 a month — or $5,000 a year — for the chance to attend an event where he will speak. . . . But the $85 a month just touches the hem of rationality. After the neophyte passes through the successively more expensive ‘Darwin Circle’ and then the ‘Evolution Circle’, he attains the innermost circle, where for $100,000 a year or more he gets to have a private breakfast or lunch with Richard Dawkins, and a reserved table at an invitation-only circle event with ‘Richard’ as well as ‘all the benefits listed above’, so he still gets a discount on his Richard Dawkins T-shirt saying ‘Religion — together we can find a cure.

The website suggests that donations of up to $500,000 a year will be accepted for the privilege of eating with him once a year: at this level of contribution you become a member of something called ‘The Magic of Reality Circle’.  I don’t think any irony is intended.

Just as religion is a hustle for some, anti-religion is for others.

Jerry Coyne's Latest Outburst re: Pope Francis, Big Bang and Evolution

It doesn't merit a lot of attention, but I will mention two stupid moves that Jerry  Coyne makes.  Or if not stupid, then intellectually dishonest. 

First, Coyne states that "We know now that the universe could have originated from 'nothing' through purely physical processes, if you see 'nothing' as the 'quantum vacuum' of empty space."  By the same token, we now know that Jerry Coyne is a fool if you see 'fool' as equivalent in meaning to 'one who thinks that a substantive question can be answered by a semantic trick.'

Second, Coyne maintains that the belief that human beings have souls "flies in the face of science."  In other words, the belief in question is logically inconsistent with natural science.  Why?  Because, "We have no evidence for souls, as biologists see our species as simply the product of naturalistic evolution from earlier species."  The reasoning is this:

1. Biologists qua biologists see the human biological species as simply the product of evolution.

Therefore

2. Biology uncovers no evidence of souls.

Therefore

3. Biology rules out the existence of souls.

(1) is true.  (2) is a very unsurprising logical consequence of (1).  For biology, as a natural science, is confined to the study of the empirically accessible features of living things, including human animals.  It is therefore no surprise at all that biology turns up no evidence of souls, or of consciousness or self-consciousness for that matter.   By the same token, cosmology and quantum mechanics uncover no evidence that anything is alive. 

The move from (2) to (3), however, is a howling non sequitur.  (In plain English, (3) does not logically follow from (2), and it is obvious that it doesn't.) Biology is simply in no position to uncover any evidence of souls that there might be, and it shows a failure to grasp what it is that biology studies to think that such evidence would be accessible to biology.

To argue from (2) to (3) would be like arguing from

4. Mathematics uncovers no evidence that anything in nature  can be studied using complex (imaginary) numbers.

Therefore

5. Mathematics rules out the existence of anything in nature that can be studied using complex (imaginary) numbers.

That too is a howling non sequitur: we know that alternating current theory makes essential use of complex numbers.

At the root of Coyne's foolishness is scientism, the view that the only genuine knowledge is natural-scientific knowledge. Scientism is the epistemology of naturalism, the view that reality is exhausted by the space-time system.  Both are philosophical views; neither is scientific.  There are powerful arguments against both.

Enough beating up of a cripple for one day.  And that reminds me: Nietzsche in Twilight of the Idols refers to Kant as a concept-cripple (Begriffskrueppel). What would that make Coyne?  A stillborn concept-cripple?

More critique of Coyne here.   The man should stick to biology.  And the same goes for Dawkins.

A Design Argument From Cognitive Reliability

 A theist friend requests a design argument.  Here is one.

You are out hiking and the trail becomes faint and hard to follow. You peer into the distance and see three stacked rocks. Looking a bit farther, you see another such stack. Now you are confident which way the trail goes.

Your confidence is based on your taking the rock piles as more than merely natural formations. You take them as providing information about the trail's direction, which is to say that you to take them as trail markers, as meaning something, as about something distinct from themselves, as exhibiting intentionality, to use the philosopher's term of art. The intentionality, of course, is derivative rather than original. It is not part of your presupposition that the cairns of themselves mean anything. Obviously they don't. But it is part of your presupposition that the cairns are physical embodiments of the original or intrinsic intentionality of a trail blazer or trail maintainer. Thus the presupposition that you make when you take the rock piles as providing information about the direction of the trail  is that an intelligent being designed the objects in question with a definite purpose, namely, to indicate the trail's direction.

Of course, the two rock piles might have come into existence via purely natural causes: a rainstorm might have dislodged some rocks  with gravity plus other purely material factors accounting for their placement. And their placement might be exactly right.  Highly unlikely, but possible. This possibility shows that the appearance of design does not entail design.  A stack of rocks may appear to be a cairn without being one.  A cairn, by definition, is a marker or memorial, and thus an embodiment of meaning, meaning it cannot possess intrinsically in virtue of its mere physicality, e.g., its being a collocation of bits of rhyolite. 

Nevertheless, your taking of the rock piles as trail markers presupposes (entails) your belief that they were put there by someone to mark the trail.  It would clearly be irrational to take the piles as evidence of the trail's direction  while at the same time maintaining that their formation was purely accidental. And if you later found out that they had come into being by chance due to an earthquake, say, you would cease interpreting them as meaning anything, as providing information about the trail. One must either take the rock piles as meaningful and thus designed or as undesigned and hence meaningless. One cannot take them as both  undesigned and meaningful. For their meaning -- 'the trail goes that-a-way' -- derives from a designer whose original intentionality is embodied in them.

In short: the rock stacks have no meaning in themselves.  They have meaning only as embodying the original intentionality of someone who put them there for a purpose: to show the trail's direction.  The hiker who interprets the stacks as meaningful presupposes that they are embodiments or physical expressions of original intentionality and not accidental collocations of matter.

Now consider our incredibly complex sense organs and brain. We rely on them to provide information about the physical world. I rely on eyesight, for example, both to know that there is a trail and to discern some of its properties. I rely on hearing to inform me of the presence of a rattlesnake. I rely on my brain to draw inferences from what I see and hear, inferences that purport to be true of states of affairs external to my body. The visual apparatus (eye, optic nerves, visual cortex and all the rest) exhibits apparent design. It is as if the eyes were designed for the purpose of seeing. As we say colloquially, eyes are for seeing.  But the appearance of design is no  proof of real design. And indeed, human beings with their sensory  apparatus are supposed to have evolved by an unguided  process of natural selection operating upon random mutations. If so, eye and brain are cosmic accidents.  The same goes for the rest of our cognitive apparatus: memory, introspection, reason, etc.

But if this is the case, how can we rely on our senses to inform us about the physical world? If eye and brain are cosmic accidents, then  we can no more rely on them to inform us about the physical world than we can rely on an accidental collocation of rocks to inform us about the direction of a trail.

As a matter of fact, we do rely on our senses. Our reliance may be mistaken in particular cases as when a bent stick appears as a snake. But in general our reliance on our senses for information about the world seems  justified. Our senses  thus seem reliable: they tend to produce true beliefs more often than not when functioning properly in their appropriate environments. We rely on our senses in mundane matters but also when we do science, and in particular when we do evolutionary biology. The problem is: How is our reliance on our sense organs justified if they are the accidental and undesigned products of natural selection operating upon random mutations?

To put it in terms of rationality: How could it be rational to rely on our sense organs (and our cognitive apparatus generally) if evolutionary biology under its naturalistic (Dawkins, Dennett, et al.) interpretation  provides a complete account of this cognitive apparatus? How could it be rational to affirm both that our cognitive faculties are reliable, AND that they are accidental products of blind evolutionary processes? That would be like affirming both that the cairns are reliable trail indicators AND that they came about by unguided natural processes.  I agree with Richard Taylor who writes:

     . . . it would be irrational for one to say both that his sensory
     and cognitive faculties had a natural, nonpurposeful origin and
     also that they reveal some truth with respect to something other
     than themselves, something that is not merely inferred from them.
     (Metaphysics, 3rd ed. p. 104)

   This train of thought suggests the following aporetic triad or antilogism:

1. It is rational to rely on our cognitive faculties to provide access to truths external to them.

2. It would not be  rational to rely on our cognitive faculties if they had come about by an unguided  process of natural selection operating upon random genetic mutations.
  
3. Our cognitive faculties did come about by an unguided process of natural selection operating upon random genetic mutations.

The limbs of the triad are individually plausible but collectively inconsistent: they cannot all be true.  From any two limbs one can validly argue to the negation of the remaining one.  So, corresponding to our antilogism there are three valid syllogisms. One of them is a design argument that argues to the negation of (3) and the affirmative conclusion that behind the evolutionary process is intelligent, providential guidance.  "And this all men call God."

To resist this design argument, the naturalist must reject either (1) or (2).  To reject (2) is to accept the rationality of believing both that our cognitive faculties arose by accident and that they produce reliable beliefs. It  is to accept the rationality of something that, on the face of it, is irrational.  To reject (1) is not very palatable either.  But I suppose one could bite the bullet and say, "Look, we are not justified in relying on our cognitive faculties, we just rely on them and so far so good."

A mysterian naturalist could say this:  Our cognitive faculties came about through an unguided evolutionary process; it is rational to rely upon them; but our cognitive architecture is such that we simply cannot understand how it could be rational to rely on processes having this origin.  For us, the problem is insoluble, a mystery, due to our irremediable  limitations.  Just because it is unintelligible to us how something could be the case, it does not follow that it is not the case. 

The best objection to this little design argument I have sketched comes from  the camp of Thomas Nagel.  Nagel could say, "You have given good reason to reject unguided evolution, but why can't the guidance be immanent?  Why must there be a transcendent intelligent being who supervises the proceedings?  Nature herself is immanently intelligible and unfolds according to her own immanent teleology.  You cannot infer theism since you haven't excluded the pansychist option."

Of course, one could beef up the design argument presented by working to exclude the panpsychist option.

Plantinga Reviews Nagel

I am beginning to feel a little sorry for Thomas Nagel.  It looks as if the only favorable mainstream reviews he will receive for his efforts in Mind and Cosmos  will be from theists.  What excites the theists' approbation, of course, are not Nagel's positive panpsychist and natural-teleological suggestions, which remain within the ambit of naturalism, but his assault on materialist naturalism.  As Alvin Plantinga writes in his excellent review, Why Darwinist Materialism is Wrong, "I applaud his formidable attack on materialist naturalism; I am dubious about panpsychism and natural teleology." And so Nagel's predicament, at least among reviewers in the philosophical mainstream, seems to be as follows.  The naturalists will reject his book utterly, both in its negative and positive parts, while the theists will embrace the critique of materialist naturalism while rejecting his panpsychism and natural-teleologism.

Plantinga's review, like ancient Gaul, est in partes tres divisa.

In the first part, Plantinga take himself to be in agreement  with Nagel on four points.  (1) It is extremely improbable that life could have arisen from inanimate matter by the workings of the laws of physics and chemistry alone.  (2) But supposing  life has arisen, then natural selection can go to work on random genetic mutations.  Still, it is incredible that that all the fantastic variety of life, including human beings, should have arisen in this way.  (3) Materialist naturalism cannot explain consciousness. (4) Materialist naturalism cannot explain belief, cognition, and reason.

In the second part of his review, Plantinga discusses Nagel's rejection of theism.  Apart from Nagel's honestly admitted temperamental disinclination to believe in God, Plantinga rightly sees Nagel's main substantive objection to theism to reside in theism's putative offense against the unity of the world.  But at this point I hand off to myself.  In my post Nagel's Reason for Rejecting Theism I give a somewhat more detailed account than does Plantinga of Nagel's rejection.

In the third part of his review, Plantina expresses his doubts about panpsychism and natural teleology.  I tend to agree that there could not be purposes without a purposer:

As for natural teleology: does it really make sense to suppose that the world in itself, without the presence of God, should be doing something we could sensibly call “aiming at” some states of affairs rather than others—that it has as a goal the actuality of some states of affairs as opposed to others? Here the problem isn’t just that this seems fantastic; it does not even make clear sense. A teleological explanation of a state of affairs will refer to some being that aims at this state of affairs and acts in such a way as to bring it about. But a world without God does not aim at states of affairs or anything else. How, then, can we think of this alleged natural teleology?

Plantinga ends by suggesting that if it weren't for Nagel's antipathy to religion, his philosophical good sense would lead him to theism.

Addendum (11/19): In case you missed it, Nagel reviewed Plantinga.

An Evolved Animal With a Higher Origin? Some Theological Speculation

I just remembered this old post from the Powerblogs site, a post relevant to present concerns.  Written February 2008.

................

I raised the question whether divine revelation is miraculous. I answered tentatively that it is not. Though revelation  may be accompanied by miraculous events such as the burning bush of  Exodus 3:2, I floated the suggestion that there need be nothing miraculous about revelation as such. So I was pleased to find some  support for this notion from another quarter. The following is from an   essay by Leo Strauss on Hermann Cohen's Religion of Reason out of the Sources of Judaism:

   
     Revelation is the continuation of creation since man as the
     rational and moral being comes into being, i.e., is constituted, by
     revelation. Revelation is as little miraculous as creation. (Leo
     Strauss, Studies in Platonic Political Philosophy, U. of Chicago
     Press, 1983, p. 237.)

This is an extremely interesting suggestion in that it may offer us a way to make sense of the notion that God creates man in his image and  likeness but without interfering in the evolutionary processes most of us believe are responsible for man's existence as an animal.

Man as an animal is one thing, man as a spiritual, rational, and moral being is another. The origin of man as an animal came about not through any special divine acts but through the evolutionary processes  common to the origination of all animal species. But man as spirit, as a self-conscious, rational being who distinguishes between good and evil cannot be accounted for in naturalistic terms.

As animals, we are descended from lower forms. As animals, we are part of the natural world and have the same general type of origin as any other animal species. Hence there was no Adam and Eve as first biological parents of the human race who came into existence directly by divine fiat  without animal progenitors. But although we are animals, we are also spiritual beings, spiritual selves. I am an I, an ego, and this I-ness or egoity cannot be explained naturalistically. I am a person possessing free will and conscience neither of which can be explained naturalistically.

I suggest that what 'Adam' refers to is not a man qua member of a zoological species, but the first man to become a spiritual self. This spiritual selfhood came into existence through an encounter with the divine self. In this I-Thou encounter, the divine self elicited or triggered man's latent spiritual self. This spiritual self did not emerge naturally; what emerged naturally was the potentiality to hear a divine call which called man to his vocation, his higher destiny, namely, a sharing in the divine life. The divine call is from beyond the human horizon.

But in the encounter with the divine self which first triggered man's personhood or spiritual selfhood, there arose man's freedom and his sense of being a separate self, an ego distinct from God and from other egos. Thus was born pride and self-assertion and egotism. Sensing his quasi-divine status, man asserted himself against the One who had revealed himself, the One who simultaneously called him to a Higher Life but also imposed restrictions and made demands. Man in his pride then made a fateful choice, drunk with the sense of his own power: he decided to go it alone. This rebellion was the Fall of man, which has nothing to do with being expelled from a physical garden located between the Tigris and Euphrates rivers. Original Sin was a spiritual event, and its transmission was not by semen,  but by some spiritual (socio-cultural) means.

If we take some such tack as the above, then we can reconcile what we know to be true from natural science with the Biblical message. Religion and science needn't compete; they can complement each other -- but only if each sticks to its own province. In this way we can avoid both the extremes of the fundamentalists and the extremes of the 'Dawkins gang' (Dawkins, Dennett, Hitchens, Harris, et al.)

Returning to Hermann Cohen's suggestion above, as mediated by Leo Strauss, we can say that the divine-human encounter whereby the animal man becomes spirit is God's revelation to man. God's revealing himself is at the same time a creation of man as a spiritual being. In Heideggerian terms, at the moment of encounter moment man becomes Dasein, the Da of Sein, the site where Being (Sein) achieves finite self-understanding. But there is nothing ontically miraculous in this, no contravention of any law of nature.

Revealing himself to man as Being itself -- Exodus 3:14 "I am who am" -- God creates man as understandor of Being.

Elliot Sober on Thomas Nagel, Mind and Cosmos

This is the fourth in a series of posts on Thomas Nagel's Mind and Cosmos (Oxford 2012).  The posts are conveniently collected under the rubric Nagel, Thomas. Before proceeding with my account of Chapter 4, I will pause in this entry to consider Elliot Sober's serious, substantial, and sober Boston Review review.  Sober's sobriety lapses only in the subtitle (which may have been supplied by the editor): "Ending Science as We Know It."

According to Sober, Nagel " . . .  argues that evolutionary biology is fundamentally flawed and that physics also needs to be rethought—that we need a new way to do science." This seems to me to misrepresent Nagel's project.  His project is not to "end science as we know it" but to indicate the limits of scientific explanation.  A legitimate philosophical task is to investigate  the limits of even the most successful sciences. (4) Now, to investigate and point out the limits of evolutionary biology and physics is not to argue that they are "fundamentally flawed."  They do what they are supposed to do, and the fact that they do not, or cannot, explain certain phenomena that certain scientistically inclined people would like them to explain, is no argument against them.  After all, physics cannot explain the proliferation of living species, but that is no argument against physics.  If evolutionary biology cannot explain how consciousness arises in certain organisms or the objectively binding character or normative judgments,  that is no argument against evolutonary biology.  To oppose Darwinian imperialism as Nagel does is not to oppose Darwinism.  To suppose that every gap in our understanding can be filled with a Darwinian explanation is  rightly ridiculed as "Darwinism of the gaps." (127)

Nagel's targets are not existing successful sciences.  He tells us right at the outset what his target is (bolding added):  "My target is a comprehensive, speculative world picture that is reached by extrapolation from some of the discoveries of biology, chemistry, and physics -- a particular naturalistic Weltanschauung that postulates a hierarchical relation among the subjects of those sciences, and the completeness in principle of an explanation of everything in the universe through their unification." (4)  He goes on to characterize this worldview as "materialist reductionism" and "reductive materialism."

Nagel is therefore not opposing any science but rather a philosophical position, materialist reductionism, that is reached by a speculative-philosophical extrapolation from some of the results of the sciences. 

Although Nagel admits that there are some brute facts, mind, the intelligibility of the world, and the fact that there are conscious organisms (45) are not among them.  Mind is not an accident or fluke (16) and "The intelligibility of the world is no accident."  One of the limits of current evolutionary theory is that it cannot explain why these remarkable fact are non-accidental.  Sober does not understand why, if some facts are brute, the remarkable facts of mind, intelligibilty and consciousness are not among them:

My philosophical feelings diverge from Nagel’s. I think that Beethoven’s existence is remarkable, but I regard it as a fluke. He could easily have failed to exist. Indeed, my jaded complacency about Beethoven scales up. I don’t think that life, intelligence, and consciousness had to be in the cards from the universe’s beginning. I am happy to leave this question to the scientists. If they tell me that these events were improbable, I do not shake my head and insist that the scientists must be missing something. There is no such must. Something can be both remarkable and improbable. 

Sober seems to be imputing to Nagel the following argument:

What is remarkable cannot be improbable.
Life, consciousness, reason, etc. are remarkable
Therefore
Life, consciousness, reason, etc. cannot be improbable.

Now this is an unsound argument, of course: Beethoven's existence was remarkable but improbable.  But this is not the way Nagel is arguing.  He needn't be read as denying that there is an element of chance in the appearance of Beethoven, a particular instance of life, consciousness, and reason.  His point is rather that consciousness and reason in general cannot be cosmic accidents.  Sober ignores what is specific to reason, and views it as just another remarkable fact.  Nagel's actual argument (see p. 86) is rather along these lines:

1. There are organisms capable of reason.
2. The possibility of such beings must have been there from the beginning.
3. This possibility, however, must be grounded in and explained by the nature of the cosmos.
4. What's more, the nature of the cosmos must explain not only the possibiity but also the actuality of rational animals: their occurrence cannot be a brute fact or accident.

I take Nagel to be maintaining that the eventual existence of some rational beings or other is no accident -- which is consistent with maintaining that there is an element of chance involved in the appearance of any particular instance of reason such as Beethoven.

Of course, Sober will still balk.  Why can't reason be a fluke?  Even if we grant Nagel that the intelligibility of nature could not have been a fluke or brute fact, how does it follow that the actual existence of some rational beings or other, beings capable of 'glomming onto' the world's intelligible structure, is not a fluke?  In a later post I will try to beef up Nagel's argument so that it can meet this demand.

For now, though, we have a stand-off.  Nagel has this deep sense, which I share, that "rational intelligibility is at the root of the natural order . . . ." (17)  Sober in his sobriety does not share that sense. 

There is more to Sober's criqiue than this, but this is enough for today. 

Wittgenstein on Darwin

One thing I definitely applaud in Wittgenstein is his opposition to scientism.   M. O'C. Drury in Conversations with Wittgenstein, ed. Rush Rhees (Oxford, 1984), pp. 160-161:

     One day, walking in the Zoological Gardens, we admired the immense
     variety of flowers, shrubs, trees, and the similar multiplicity of
     birds, reptiles, animals.

     WITTGENSTEIN: I have always thought that Darwin was wrong: his
     theory does not account for all the variety of species. It hasn't
     the necessary multiplicity. Nowadays some people are fond of saying
     that at last evolution has produced a species that is able to
     understand the whole process which gave it birth. Now that you
     can't say.

     DRURY: You could say that now there has evolved a strange animal
     that collects other animals and puts them in gardens. But you can't
     bring the concepts of knowledge and understanding into this series.
     They are different categories entirely.

     WITTGENSTEIN: Yes, you could put it that way.

To imagine that evolutionary theory could cast light on the concepts of knowledge and understanding involves a massive metabasis eis allo genos, to use a a favorite Greek phrase of Kierkegaard.

Plantinga Versus Dawkins: Organized Complexity

This is the third in a series on Plantinga's new book.  Here is the first, and here is the second.  These posts are collected under the rubric Science and Religion besides being classified under other heads.  This third post will examine just one argument of Dawkins' and Plantinga's response to it, pp. 26-28. Here is Plantinga in Chapter One of Where the Conflict Really Lies quoting from Dawkins' The Blind Watchmaker, p. 141.  (The ellipses are Plantinga's; the emphasis is Dawkins'; I have added a sentence from Dawkins that Plantinga did not quote; and I should note that Plantinga gives the wrong page reference.  The passage is on 141, not 140.)

Organized complexity is the thing we are having difficulty in explaining. Once we are allowed simply to postulate organized complexity, if only the organized complexity of the DNA/protein replicating engine, it is relatively easy to invoke it as a generator of yet more organized complexity. . . .  But of course any God capable of intelligently designing something as complex as the DNA/protein replicating machine must have been at least as complex and organized as that machine itself. .... To explain the origin of the DNA/protein machine by invoking a supernatural Designer is to explain precisely nothing, for it leaves unexplained the origin of the Designer. You have to say something like "God was always there", and if you allow yourself that kind of lazy way out, you might as well just say "DNA was always there", or "Life was always there", and be done with it. (1986, p. 141)

Dawkins seems to me to be arguing as follows.

1. What is needed is an explanation of organized complexity as such.
2. God is an instance of organized complexity.
3. If God is invoked as that whose existence and operation explains organized complexity as such, then the explanation is manifestly circular: the explanandum has been imported into the explanans.
4. Circular explanations are worthless: they explain nothing.
Therefore
5. To posit God as cosmic designer fails as an explanation of organized complexity as such.

The argument on my reconstruction is unexceptionable, but how is it relevant? if the task is to explain organized complexity as such, this cannot be done via an instance of it.  No doubt.  But the argument misses the point.  The point is not to explain organized complexity as such, or even the organized complexity of all actual or possible life, but to explain the organized complexity of terrestrial life.  More precisely, the point is to show that this cannot be done by invoking God in one's explanation.  Obviously the argument as reconstructed does not succeed in showing that.

Note that there is no mention of any facts of biology in the above argument.  Now Plantinga doesn't say the following, but I will: the argument is purely a priori.  It is a proof, from concepts alone and without recourse to empirical facts, that an explanation of organized complexity as such cannot be had if the explanans mentions an instance of organized complexity.  How then, Plantinga asks, does the (empirical) evidence of evolution reveal a world without design? (p. 27)

Now suppose we substitute the following proposition for (1):

1* What is needed is an explanation of the organized complexity of terrestrial life.

But if we plug (1*) into the original argument, and modify (3) accordingly, then (3) is false and the argument is unsound.  If we are not trying to explain organized complexity in general, but only the organized complexity of terrestrial life, then there is nothing fallacious about invoking an explainer that is an instance of organized complexity.

The Dawkins passage suggests another sort of argument, oft-heard:  If there is a supernatural designer, what explains his existence?  If you say that God always existed, then you may as well say that life always existed.

This puerile argument is based on a failure to understand that explanations, of necessity, must come to an end.

Why did that tree in my backyard die?  Because subterranean beetles attacked its roots.  If the explanation is correct, it is correct whether or not I can explain how the subterranean beetles got into the soil, or which other beetles were their parents, and grandparents, etc.  Explanations come to an end, and an explanation of a given phenomenon in terms of its proximate cause can be perfectly adequate even in the absence of explanations of other events in the explanandum's causal ancestry.

It is the puerile atheist who demands to know what caused God.  As Plantinga remarks, "Explanations come to an end; for theism they come to an end in God." (p. 28)  I would add that this is obvious if God is an necessary being: such a being is in no need of explanation.  But it holds also if God is a contingent being.  For again, not everything can be explained.

But if God was "always there" as Dawkins puts it, why not say that life was "always there"?  Because life wasn't always there! 

Ultimately, the theist explains everything in terms of the divine mind.  Since explanations must come to an end, the theist has no explanation of the existence or complexity of the divine mind.  But, as Plantinga remarks, p. 28, the materalist or physicalist is in the same position. He cannot explain everything. He "doesn't have an explanation of the existence of elementary particles or, more generally, contingent physical or material beings . . . ." (28)  I would also ask whether the materialist can explain why there are natural laws at all, why the universe is intelligible in terms of them, and why there are these laws and constants rather than some other possible set. 

There is one point that ought to be conceded to Dawkins, however.  It certainly would be a "lazy way out" to invoke divine intervention in cases where  a naturalistic explanation is at hand. 

So far, then, Plantinga 1, Dawkins 0.

Plantinga's Where the Conflict Really Lies: Notes on Chapter One

This is the second in a series on Alvin Plantinga's latest book.  The first post, on the preface, provides bibliographical details and an overview of Plantinga's project.  In this post I will merely set forth what Plantinga understands by Christian belief and what he understands by evolution and where he sees real conflict between the two.  Things will heat up a bit in my third post wherein I will come to grips with Plantinga's critique of Richard Dawkins.  There is a lot of good material that I won't mention, in particular, the discussion on pp. 4-5 on the narrow and broad construals of imago Dei.

A. Plantinga proposes that we take Christian belief "to be defined or circumscribed by the rough intersection of the great Christian creeds: the Apostle's Creed, the Nicene Creed, and the Athanasian Creed . . ." but not in a manner to exclude particular creeds.  (p. 8) The "rough intersection" of all of this is ably presented in C. S. Lewis's Mere Christianity.

B. As for evolution, Plantinga distinguishes six theses (pp. 8-10):

1. Ancient Earth Thesis:  The earth is "perhaps some 4.5 billion years old."
2. Progress Thesis: "life has progressed from relatively simple to relatively complex forms . . . ."
3. Descent with Modification Thesis:  "The enormous diversity of the contemporary living world has come about by way of off-spring differing, ordinarily in small and subtle ways, from their parents."
4. Common Ancestry Thesis:  "life originated at only one place on earth, all subsequent life being related by descent to those original living creatures . . . ."
5. Darwinism: "there is a naturalistic mechanism driving this process of descent with modification: the most popular candidate is natural selection operating on random genetic mutation . . . ."
6. Naturalistic Origins Thesis:  "life itself developed from non-living matter without any special creative activity of God but just by virtue of processes described by the ordinary laws of physics and chemistry. . . ."

Plantinga uses 'evolution' to refer to the first four theses, and 'Darwinism' to refer to "the mechanism allegedly underlying evolution." He adds that "the sixth thesis thesis "isn't really part of the theory of evolution."

Now where is there real conflict wth Christian belief?  That God created  man in his image is an absolutely  nonnegotiable element of Christian belief. But on Plantinga's account it does not conflict with any of (1)-(4) or with all of them taken together.  Nor does it conflict with Darwinism, the fifth thesis, "the view that the diversity of life has come to be by way of natural selection winnowing random genetic mutation.  God could have caused the the right mutations to arise at the right time . . . and in this way he could have seen to it that there come to be creatures of the kinds he intends." (p. 11)

This will of course sound crazy to a naturalist.  Every naturalist is an atheist (though not conversely), and most atheists consider the notion that there is a purely spiritual, providential being superintending and directing the goings-on of the physical universe to be risible, a childish fantasy on the order ot the Tooth Fairy, and as such  simply beneath serious discussion. But in point of strict logic, there is nothing inconsistent in one's maintaining all of (1)-(5) and the proposition that evolution is divinely guided.

But how could random genetic mutations be caused by God?  Doesn't 'random' imply 'uncaused'?  No. Plantinga quotes biologist Ernst Mayr, and philosopher of biology Elliot Sober.  The following is from a credible source  I found:

Mutations can be beneficial, neutral, or harmful for the organism, but mutations do not "try" to supply what the organism "needs." Factors in the environment may influence the rate of mutation but are not generally thought to influence the direction of mutation. For example, exposure to harmful chemicals may increase the mutation rate, but will not cause more mutations that make the organism resistant to those chemicals. In this respect, mutations are random — whether a particular mutation happens or not is unrelated to how useful that mutation would be. [Be sure to click on internal link.]

If mutations are random in this precise sense, that does not rule out their being caused.

Real conflict between Christian belief and evolution first arises with respect to the sixth thesis, the Naturalistic Origins Thesis.  Here is the source of the incompatibility according to Plantinga. If the sixth thesis is true, then Christian belief is false.

 A question.  Suppose all six theses are true.  Could not one still be a theist who holds that man is made in the divine image?  If the sixth thesis is true, then God does not intervene in the workings of nature.   He does not cause or prevent genetic mutations; he does not preserve certain populations from perils, etc.  He creates the universe ex nihilo and sustains it in existence moment by moment 'vertically' so to speak, but he  does not interfere 'horizontally.'  He does not insert himself, so to speak, into any unfolding causal chains.  As primary cause alone, he has nothing to do with natural, 'secondary,' causation.  Accordingly, man as an animal has a purely naturalistic origin. But of course imago Dei has nothing to do with man as an animal . . . .  Just a question, to be put on the back burner for now while we continue to examine how Plantinga's overall argument unfolds.

Where the Conflict Really Lies: Science, Religion, and Naturalism: Notes on the Preface

I now have Alvin Plantinga's new book in my hands.  Here are some notes on the preface.  Since I agree with almost everything in the preface, the following batch of notes will be interpretive but not critical.  Words and phrases  enclosed in double quotation marks are Plantinga's ipsissima verba. 

1. Plantinga is concerned with the relations among monotheistic religion, natural science, and naturalism.  His main thesis is that there is "superficial conflict but deep concord" between natural science and monotheistic religion but  "superficial concord but deep conflict" between science and naturalism. 

2. The great monotheistic religions (Judaism, Christianity, and Islam) affirm the existence of "such a person as God."  Naturalism is a worldview that entails the nonexistence of such a person.  "Naturalism is stronger than atheism." (p. ix) Naturalism entails atheism, but atheism does not entail naturalism.  One can be an atheist without being a naturalist.  John McTaggart Ellis McTaggart is an example. (My example, not Plantinga's.)  But one cannot be a naturalist without being an atheist.  This is perhaps obvious, which is why Plantinga doesn't explain it.  Roughly, a naturalist holds that the whole of reality (or perhaps only the whole of concrete reality) is exhausted by the space-time system and its contents.  No one who holds this can hold that there is such a person as God, God being a purely spiritual agent.

To put it my own way, theistic religion and naturalism could not both be true, but they could both be false.  This makes them logical contraries, not contradictories.  Their being the former suffices to put them in real conflict.  For many of us this is what the ultimate worldview choice comes down to.

3. Plantinga rightly points out that while naturalism is not a religion, it is a worldview that is like a religion.  So it can be properly called a quasi-religion.  (p. x) This is because it plays many of the same roles that a religion plays.  It provides answers to the Big Questions: Does God exist? Can we survive our bodily deaths? How should we live?

I would add that there are religious worldviews and anti-religious worldviews, but that natural science is not a worldview.  Science is not in the business of supplying worldview needs: needs for meaning, purpose, guidance, norms and values. Science cannot put religion out of business, as I argue here, though  perhaps in some ways that Plantinga would not endorse.

4. Given that naturalism is a quasi-religion, there is a sense in which there is a genuine science vs. religion conflict, namely, a conflict between science and the quasi-religion, naturalism.  Very clever!

5. Plantinga's claim that "there is no serious conflict between science and religion" puts him at odds with what I call  the Dawkins Gang and what Plantinga calls the Four Horsemen of the New Atheism: Richard Dawkins, Daniel Dennett, Christopher Hitchens, and Sam Harris.  Plantinga, who never fails us when it comes to wit and style, suggests that the atheism of these four "is adolescent rebellion carried on by other means" (p. xi)  that doesn't rise to the level of the the old atheism of Bertrand Russell and John Mackie.  "We may perhaps hope that the new atheism is but a temporary blemish on the face of serious conversation in this crucial area."  That is indeed the hope of all right-thinking and serious people, whether theists or atheists.

6. Plantinga fully appreciates that modern natural science is a magnficent thing, "the most striking and impressive intellectual phenomenon of the last half millenium." (p. xi)  This has led some to the mistake of thinking that science is the ultimate court of appeal when it comes to the fixation of belief.  But this can't be right for two reasons.  First, science gives us no help in the areas where we most need enlightenment: religion, politics, and morals, for example. (p. xii)  There are worldview needs, after all, and science cannot supply them.  "Second, science contradicts itself, both over time and at the same time." (p. xii)  Indeed it does.  But no one, least of all Plantinga,  takes that as an argument against science as open-ended inquiry.  A question to ruminate on:  Should not religion also be thought of as open-ended and subject to correction?

7.  I would say that if there is demonstrable conflict between a religious belief and a well-established finding of current natural science, then the religious belief must give way.  Plantinga commits himself to something rather less ringing: if there were such a conflict, then "initially, at least, it would cast doubt on those religious beliefs inconsistent with current science."(p. xii).  But he doesn't think there is any conflict between "Christian belief and science, while there is conflict between naturalism and science." 

8. One apparent conflict is between evolution and religion, another between miracles and science.  Plantinga will argue that these conflicts are merely apparent.  Theistic religion does not conflict with evolution but with a "philosophical gloss or add-on to the scientific theory of evolution: the claim that it is undirected . . . ." (p. xii) As for miracles, Plantinga says he will show that they do not violate the causal closure of the physical domain and the various conservation laws that govern it. "Any system in which a divine miracle occurs . . . would not be causally closed; hence such a system is not addressed by those laws." (p. xiii)  That sounds a bit fishy, but we shall have to see how Plantinga develops the argument.

9. As for the "deep concord" between theistic thinking and science, it is rooted in the imago Dei.  If God has created us in his image, then he has created us with the power to understand ourselves and our world.  This implies that he he has created us and our world "in such a way that there is a match between our cognitive powers and the world." (p. xiv)  I would put it like this: both the intelligibility of the world and our intelligence have a common ground in God.  This common ground or source secures both the objectivity of truth and the possibility of our knowing some of it, and thereby the possibility of successful science.

10.  But when it comes to naturalism and science, there is "deep and serious conflict."    Naturalism entails materialism about the human mind.  It entails that we are just complex physical systems.  If so, then Plantinga will argue that "it is improbable, given naturalism and evolution, that our cognitive faculties are reliable."  If this can be shown, then the conjunction of naturalism and evolution is not rationally acceptable. "Hence naturalism and evolution are in serious conflict: one can't rationally accept them both." (p. xiv)  

Original Sin in a Darwinian World

Our old friend Jeff Hodges of Gypsy Scholar e-mails: 

I liked the interesting argument that the consequences of belief and nonbelief in original sin are both bad and thus evidence of our fallen natures. But I do wonder what either original sin or fallenness mean in a Darwinian world . . .

Jeff has posed an excellent question which I must try to answer.

1. I begin with what it can't mean.  It cannot mean that our present fallen condition is one we inherited from Adam and Eve if these names refer to the original parents of the human race.  And this for two reasons.

A. The first is that nothing imputable to a person, nothing for which he is morally responsible, can be inherited.  For what I inherit I receive ab extra by causal mechanisms not in my control.  (It doesn't matter whether these mechanisms are deterministic or merely probabilistic.)  That which is imputable to me, however, is only that which I freely bring about.  It is a clear deliverance of our ordinary moral sense that a person is morally responsible only for what he does and leaves undone, not for what others do or leave undone.  This deliverance is surely more credible than any theory that entails its negation.  So one cannot inherit sinfulness, guilt, or desert of punishment.  Therefore the actual sins of past persons cannot induce in me a state of sinfulness or guilt or desert of punishment.  And that includes the actual sins of our first parents if there were any.

This amounts to a denial of originated original sin.  It does not amount to a denial of originating original sin.  The distinction is explained in greater detail here.  So there can still be original sin even if sinfulness, guilt, and desert of punishment cannot be inherited.

As I said elsewhere, we must distinguish between the putative fact of original sin and the various theories one can have of it.  Refuting a particular theory does not amount to refuting the fact.

B. The second reason is that there were in actual historical fact no original parents of the human race who came into existence wthout animal progenitors.  We know this from evolutionary biology which is more credible -- more worthy of belief -- than the stories of Genesis interpreted literally.  In any conflict between the Bible so interpreted and natural science, the latter will win -- every time.  So if one takes both Bible and science seriously, the Bible must be read in such a way that it does not conflict with our best science.

2. To take this whole original sin problematic seriously one must of course assume that in some sense or other 'Man is a fallen being.'   I warmly recommend the study of history to those who  adhere to such delusions of the Left as that of human perfectibility or the inherent goodness of humanity.  Once you disembarrass yourself of those illusions you will be open to something like human fallenness or Kant's radical evil.  I am not saying that the horrors of history by themselves entail man's fallenness.  Our fallenness is certainly not a plain empirical fact as G. K. Chesterton and others have foolishly and tendentiously suggested.  Chesterton's "plain as potatoes" remark was silly bluster.  It is rather that a doctrine of the fall is reasonably introuduced, by a sort of inference to the best explanation, to account for man's universal wretchedness and inability to substantially improve his lot. The details of the inferential move from what could count as plain facts to a doctrine of a fall is not my present topic. 

3. Now to Jeff's question.  If the Genesis stories cannot be read as literally true accounts of actual historical facts, if we accept the findings and theories of evolutionary biology as regards the genesis of human animals, then what can human fallenness mean? There are various possibilities.  I will mention just one, which derives from Kant. 

What we need is a theory that allows us to embrace all of the following propositions without contradicting any deliverance of natural science or any deliverance of our ordinary sound moral sense:

a. There is a universal propensity to moral evil in human beings which is radical in that it is at the root of every specific act of wrong-doing.
b. This propensity to evil is the best explanation of the fathomless horrors of the human condition.
c. The radical propensity to moral evil is innate in that it not acquired at any time in a moral agent's life, but is present at every time precisely as the predisposition to specific evil acts.
d. The propensity is imputable. 
e. The propensity is not inherited. 
f.  Imputable actions and states are free and unconditioned.

Here is a quick and dirty sketch of Kant's theory, a theory which allows one to affirm each of the six propositions above.

Man enjoys dual citzenship.  As a physical being, and thus as an animal, he he is a member of the  phenomenal world, the world of space-time-matter.  In this realm determinism reigns: everything that happens is necessitated by the laws of nature plus the initial conditions.  But man knows himself to be morally responsible, and so knows himself to be libertarianly free.  Since everything phenomenal is determined, and nothing free, man as moral agent is a noumenal being who 'stands apart from the causal nexus.'

Kant sees with blinding clarity that nothing imputable to an agent can be caused by factors external to the agent: only that which the agent does or leaves undone freely and by his own agency is imputable to the agent.  It follows that sinfulness, guilt, and desert of punishment cannot be inherited:  there is no originated original sin. For what is inherited is caused to be by factors external to the agent.  So (e) is true.  But the predisposition to moral evil is nonetheless innate in the sense that it is not conditioned by events in time.  It is logically prior to every action of the agent in the time-order.

How is the predisposition imputable?  It is imputable because it is the result of a free noumenal choice.  And so there is originating original sin.  Each of us by an atemporal noumenal choice is the origin of the radical evil which is at the root of each specific evil act. So (d) is true.

Kant's theory has its problems which I have no desire to paper over.  But it does provide an answer to Jeff's question.  His question, in effect, was what original sin or human fallenness could mean if Darwinism is true. Kant's theory counts as an answer to that question.  For on Kant's theory there is no need to contradict evolutionary biology by positing two original parents of the human race, nor any need to accept the notion that moral qualities such as guilt are biologically transmissible, or the morally unacceptable notion that such qualities are in any way (biologically, socio-culturally) inheritable. 

Nagel on Evolutionary Naturalism and the Fear of Religion

I have in my hand a copy of Thomas Nagel, The Last Word (Oxford University Press, 1997). The last essay in The Last Word is entitled, "Evolutionary Naturalism and the Fear of Religion." One hopes that Nagel does not consider it the last word on the topic given its fragmentary nature and occasional perversity. But it's a good essay nonetheless. Everything by Thomas Nagel is worth reading.  Herewith, a bit of interpretive summary with quotations and comments.

Nagel's essay begins by pointing out a certain Platonism in the philosophy of Charles Sanders Peirce, a Platonism that is foreign to pragmatism as usually understood. Nagel quotes Peirce as saying that the aim of science is "eternal verities," a notion at odds with the Jamesian view that the true is that which it is good for us to believe. What science is after is not a set of beliefs conducive to our flourishing but a set of beliefs that correspond to the world as it is independently of us. The researcher aims to "learn the lesson that nature has to teach. . . ." But to do this, the inquiring mind must "call upon its inward sympathy with nature, its instinct for aid, just as we find Galileo at the dawn of modern science making his appeal to il lume naturale [the natural light]. . . ."

Nagel finds these "radically antireductionist" and "realist" thoughts "entirely congenial" but "quite out of keeping with present fashion." (129) And talk of an "inward sympathy" of the inquiring mind with nature he finds "alarmingly Platonist."

But why should Nagel be alarmed at the Platonist view that reason operating properly mirrors the antecedent structure of reality? His alarm is rooted in the suspicion that the Platonist view is "religious, or quasi-religious." (130) A rationalism such as the Platonic "makes us more at home in the universe than is secularly comfortable." (130, emphasis in original.) That there should be a fundamental harmony between mind and world makes people "nervous" nowadays. This uncomfortableness and nervousness is one manifestation of the fear of religion in intellectual life.

Nagel makes it clear that he is talking about the fear of religion as such, and not merely fear of certain of its excesses and aberrations, and confesses that he himself is subject to this fear:

I speak from experience, being strongly subject to this fear myself: I want atheism to be true and am made uneasy by the fact that some of the most intelligent and well-informed people I know are religious believers. It isn't just that I don't believe in God and, naturally, hope there is no God! I don't want there to be a God; I don't want the universe to be like that. (130, emphasis added)

Nagel admits that he may just have a "cosmic authority problem." But then he says something very perceptive in a passage that may be directed against Richard Dawkins and Daniel Dennett:

My guess is that this cosmic authority problem is not a rare condition and that it is responsible for much of the scientism and reductionism of our time. One of the tendencies it supports is the ludicrous overuse of evolutionary biology to explain everything about life, including everything about the human mind. (131)

Let me give an example of my own of the overuse of evolutionary biology. After Dawkins introduced the term 'meme' along about 1976, Dennett ran with it like a crazed footballer. Roughly, a meme is a self-replicating entity that plays on the cultural level the role that the gene plays on the biological level. They are like ideas, except that they are thought of -- literally, Dennett assures us -- as brain parasites. (Consciousness Explained, p. 220) A brain infested with these self-replicating parasites is really all that a mind is: "a human mind is itself an artifact created when memes restructure a human brain in order to make it a better habitat for memes." (CE, p. 207)

Now this is not the place to begin a critique of the meme meme; my only point for the nonce is that Nagel is on to something. Fear of religion with its attendant cosmic authority problem may well be a good part of what is driving this 'philosophy fiction' of Dennett and other fanciful ideas that stem from the ludicrous overuse of evolutionary biology.

Consciousness: What Evolutionary Good Is It?

Bear in mind that the word 'consciousness' has several distinct meanings. 'Consciousness' can refer to the state of being awake, to the ability to introspect internal states, and to the phenomenon of attention. But 'consciousness' insofar as it poses a 'hard problem' for physicalists is the subjective quality of experience.

These subjective qualities can be features of sensations, but they need not be. Smashing my knee against a table leg elicits a certain unpleasant sensation. The felt quality of that sensation is an example of a conscious datum in the relevant sense. But so is the shimmering quality of a magnificent Saguaro cactus standing sentinel on a distant ridgeline as viewed in the lambent light of the desert Southwest. Qualia, then, can be associated with intentional objects and not merely with non-intentional states like sensations. Pressing some Husserlian jargon into service, we might distinguish between noematic qualia and hyletic qualia.

But the main question I want to pose is this: What good is consciousness from an evolutionary perspective? Owen Flanagan,  Consciousness Reconsidered,  MIT 1992, p. 42) has this to say:

What function might sensory or perceptual consciousness serve? Such consciousness could enable an organism to be sensitive to stimulus saliencies relevant to its suvival and to coordinate its goals with these saliencies. Informational sensitivity without experiential sensitivity (of the sort an unconscious robot might have) could conceivably serve the same function. Indeed, it often does. But the special vivacity of perceptual experience might enable quicker, more reliable, and more functional responses than a less robustly phenomenological system, and these might have resulted in small selection pressures in favor of becoming a subject of experience. At least this is one possible explanation for why Mother Nature would have selected a mind with capacities for robust phenomenological feel in the sensory modalities. It is good that reptiles are sensitive detectors of earthquakes. It enables them to get above ground before disaster hits. It is good that we feel pain. It keeps us from being burned, cut, and maimed. . . . Like photoreceptor cells designed for vision and wings for flight, the capacity to experience pleasure and pain is a design solution that Mother Nature has often used in different lineages of locomoting organisms.

I judge this to be a complete failure as an explanation of why consciousness has evolved. All the jobs Flanagan mentions might have been done 'in the dark' by unconscious processing. Yes, pain is good insofar as it keeps us from being burned, cut, and maimed. But pain in this sense is just the sum-total of physical events that play a certain causal role, that of causing the organism to withdraw or protect a part of its body on the occasion of a certain input. Think of a robotic arm equipped with heat sensors. It is designed to retract when the object it touches is at a certain temperature or above. The arm can function perfectly well without feeling anything.

Let's not forget that words like 'pain' lead a double life. 'Pain' is used to refer both to physical events and to their phenomenal manifestation. Phenomenal pain, far from being good, is evil, a form of natural evil. Insofar as it is (instrumentally) good, pain is not felt or phenomenal pain but the physical events that may or may not manifest themselves at the level of consciousness.

Consciousness is real -- eliminativism is for lunatics -- and so consciousness must be explained. But an evolutionary explanation is inadequate. Such an explanation must specify a survival function consciousness serves that could not be served without it. But what could that be? Thus I think David Chalmers (The Conscious Mind, Oxford 1996, p. 120) is on the right track:

The process of natural selection cannot distinguish between me and my zombie twin. Evolution selects properties according to their functional role, and my zombie twin performs all the functions that I perform just as well as I do; in particular he leaves around just as many copies of his genes. It follows that evolution alone cannot explain why conscious creatures rather than zombies evolved.

Chalmers also points out that

. . . the real problem with consciousness is to explain the principles in virtue of which consciousness arises from physical systems. Presumably these principles -- whether they are conceptual truths, metaphysical necessities, or natural laws -- are constant over space-time: If a physical replica of me had popped into existence a million years ago, it would have been just as conscious as I am. The connecting principles themselves are therefore independent of the evolutionary process. While evolution can be very useful in explaining why particular physical systems have evolved, it is irrelevant to the explanation of the bridging principles in virtue of which some of these systems are conscious. (p. 121)

This strikes me as an extremely important point. If we think of evolutionary genesis as proceeding 'horizontally,' then the arisal of consciousness can be thought of as 'vertical.' If we want to explain how consciousness arises from its physical substratum, it is simply irrelevant to be given an explanation of how certain traits were selected for. An evolutionary account might explain 'horizontally' how an organism became sufficiently complex to host consciousness, but such an account would do nothing to explain how consciousness arose 'vertically' from the organism.

Jeff Skilling's Favorite Book

I learned just yesterday that The Selfish Gene is (or was) Enron's Jeff Skilling's favorite book, which begs raises the question:  Was Skilling Misled by Dawkins?

Public Education and Intelligent Design

A 2008 article by Thomas Nagel.  Ladder Man calls it "comically bad."  You decide who the joker is.

Do You Understand Natural Selection?

A tip of the hat to John Farrell for drawing  my attention to T Ryan Gregory's  Understanding Natural Selection: Essential Concepts and Common Misunderstandings.  A paper well worth careful study.  Points out a surprising lack of understanding of natural selection among biology teachers.  Supports the point of view I defend in the posts in the Darwinism and Design category.

Are Biological Functions Observer-Relative?

The following three positions need to be distinguished:

1. There is design in nature, and a complete account of it is impossible without recourse to a cosmic designer such as God.
2. There is intrinsic design in nature, and it is wholly explainable in naturalistic terms.
3. There is no intrinsic design in nature: all features that exhibit design, purpose, function are observer-relative, and the only observers are themselves denizens of the natural world.

Theists who rely on design arguments subscribe to (1), while some naturalist philosophers come out in favor of (2). (2), however, involves the claim that there is intrinsic design in nature, a claim that is far from obvious, and is arguably inconsistent with Darwinism. The point of Darwinism is that what looks to be designed, in reality is not, but can be accounted for in terms of mechanistic, non-teleological processes of random variation and natural selection.  If we are using the term 'design' strictly and without equivocation -- and thus not confusing 'design' in the present sense with 'design' in the sense of pattern or shape -- then nothing can exhibit design unless there is a designer responsible for the thing's design.  If someone were to say that natural selection designed birds' wings so that they can evade their predators they would be gulty of a two-fold fallacy: first, the fallacy of hypostatizing natural selection, and second, the mistake of supposing that birds' wings exhibit an intrinsic designedness.

Ernst Mayr on Natural Selection

Another of the concepts we need to be clear about is that of natural selection. What I will do in this post is pull some quotations from Ernst Mayr, What Evolutions Is (Basic Books, 2001), and raise some questions. An important point will emerge: natural selection is not teleological!

The Concept of Design

To move towards a resolution of some of the questions posed in the comment threads to recent posts it is necessary to back up and try to clarify some of the fundamental terms in the debate. One of them is 'design.'

Our starting point must be ordinary language. As David Stove points out, "it is a fact about the meaning of a common English word, that you cannot say that something was designed, without implying that it was intended; any more than you can say that a person was divorced, without implying that he or she was previously married." (Darwinian Fairytales, p. 190, emphasis added.) In other words, it is an analytic proposition that a designed object is one that was intended in the same way that it is an analytic proposition that a divorced person is one who was previously married. These are two conceptual truths, and anyone who uses designed object and divorced person in a way counter to these truths either does not understand these concepts or else has some serious explaining to do.

I should think that Richard Dawkins has some serious explaining to do. Consider the subtitle of The Blind Watchmaker. It reads: Why the evidence of evolution reveals a universe without design.

Now I think I understand that. What Dawkins will do in his book is argue how the modern theory of evolution shows that the natural universe as a whole and in its parts is in no way the embodiment of the intentions and purposes of any intelligent being. Thus a bat, a piece of "living machinery," is such that "the 'designer' is unconscious natural selection." (p. 37) The scare quotes show that Dawkins is not using 'designer' literally. What he is saying, putting the point in plain English, is that there is no designer. For if there were a designer, then he would be contradicting the subtitle of his book, which implies that no part of nature is designed. So far, so good.

Unfortunately, on the same page Dawkins says the following about Paley:

His hypothesis was that living watches were literally designed and built by a master watchmaker. Our modern hypothesis is that the job was done in gradual evolutionary stages by natural selection.

But now we have a contradiction. We were told a moment ago that there is no designer. But now we are being told that there is a designer. For if the design job is done by natural selection, then natural selection is the designer.

Now which is it? Is there a designer or isn't there one? Dawkins cannot have it both ways at once.  If there is no designer, then natural selection cannot be the designer.  What this contradiction shows is that Dawkins is using 'design' and cognates in an unintelligible way.

Some will say I am quibbling over words. But I am not. The issue is not about words but about the concepts those words are used to express. I am simply thinking clearly about the concepts that Dawkins et al. are deploying, concepts like design.

If you tell me that design in nature is merely apparent, and that in reality nothing is designed and everything can be explained mechanistically or non-teleologically, then I understand that whether or not I agree with it. But if you tell me that there is design in nature but that the designer is natural selection, then I say that is nonsense, i.e. is unintelligible.

One cannot have it both ways at once. One cannot make use of irreducibly teleological language while in the next breath implying that there is no teleology in nature. The problem is well expressed by Stove:

. . . ever since 1859, Darwinians have always owed their readers a translation manual that would 'cash' the teleological language which Darwinians avail themselves of without restraint in explaining particular adaptations, into the non-teleological language which their own theory of adaptation requires. But they have never paid, or even tried to pay, this debt. (DF 191)
