Remember Moritz Schlick? He wrote, "All real problems are scientific questions; there are no others." ("The Future of Philosophy" in The Linguistic Turn, ed. R. Rorty). The Schlickian dictum sires an antilogism.
1) All real problems are scientific.
2) The problem whether all real problems are scientific is real.
3) The problem whether all real problems are scientific is not scientific.
Each of these propositions is plausible, but they are collectively inconsistent: they cannot all be true. Which member of the trio should we reject?
I reject (1). There are real (genuine) problems that are not scientific in the way that the natural sciences are scientific. Scientific problems are amenable in principle to solution by empirical observation and experiment. This is not so for (1). So I must disagree with Schlick the positivist.
This entry is installment #2 in a Carnap versus Heidegger series. Here is the first in the series. It couldn't hurt to at least skim through it. Part of what I am up to is an exploration of the origin and nature of the analytic-Continental split. To quote from the first installment:
If I were were to select two writings that best epitomize the depth of the Continental-analytic clash near the time of its outbreak, they would be Heidegger's 1929 What is Metaphysics? and Carnap's 1932 response, "On the Overcoming of Metaphysics Through the Logical Analysis of Language." (In fairness to Carnap, let us note that his Erkenntnis piece is more than a response to Heidegger inasmuch as it calls into question the meaningfulness of all metaphysics. And in fairness to Heidegger, we should note that he thinks he is doing something more radical than metaphysics. Metaphysics for Heidegger is onto-theology. Metaphysics thinks Being (das Sein) but always in reference to beings (das Seiende); it does not think Being in its difference from beings. Perhaps in a later post I will venture to explain what that means.)
Analytic philosophers prize clarity. And rightly so. For one thing, "clarity is courtesy," as Ortega y Gasset once said. (I suppose the Spaniard would count as Continental, and not just geographically.) One more parenthetical remark before getting down to business: I wish Erich Pryzwara had received the message that clarity is courtesy. Then perhaps he would not have written anything as unreadable as his Analogia Entis. Even the charitable German Thomist Josef Pieper so characterized it.
I need waste no words defending the thesis that clarity in thought and expression are to be preferred to obscurity. Avoidable obscurity must be avoided. But there is an empty and trivial clarity. A clarity worth pursuing is a clarity with content. Clarity ought not be pursued as an end in itself or as a cognitive value that trumps every other cognitive value. While avoidable obscurity must be avoided, some obscurity is bound to be unavoidable if our inquiries are serious, sustained, and worth pursuing. Such obscurity must be tolerated.
One day in class I was praising clarity and its importance. A student responded that reality is messy. My counter-response was that, while reality is messy, it does not follow that our thinking about it should also be. On the contrary! The present point, however, is that thinking worth doing ought to penetrate as far as it can into reality, as rich, dark, and messy as it is, and if some obscurity proves unavoidable, then so be it.
Rudolf Carnap's brand of clarity is sterile, arbitrary and as artificial as fluorescent light. What he does is enforce or impose an arbitrary standard of clarity across the board without regard to differences in subject matter. We ought to say about clarity what Aristotle said about precision near the beginning of the Nicomachean Ethics: "it cannot be expected in the treatment of all subjects alike . . . ." (1094b10-15) Ethics, the Philosopher said, cannot be treated with mathematical precision. The same goes for metaphysics.
"Many words of metaphysics," Carnap tells us, are "devoid of meaning." ("The Elimination of Metaphysics Through Logical Analysis of Language" in A. J. Ayer, ed., Logical Positivism, The Free Press, 1959, p. 65.) He chooses as his first example 'principle' "in the sense of principle of being, not principle of knowledge or axiom." (65) But since 'principle' in the ontological sense is not much used these days outside of scholastic circles, let me substitute 'ground' used ontologically. Thus there is a large body of literature in which truth-makers are described as the 'ontological grounds' of truths. It is clear that Carnap's accusations of (cognitive) meaninglessness apply as much to grounds as to principles. They also apply to other words and phrases in the vocabulary of truth-maker theorists such as 'makes true' and 'in virtue of.' For example, 'Peter is smoking' is true in virtue of Peter's smoking, or the fact of Peter's smoking makes true 'Peter is smoking.' Apart from truth-maker theory, 'in virtue of' has long been a favorite of philosophers. Some think it a 'weasel phrase' best banished from the vocabulary of philosophy. I disagree.
"But these words are ambiguous and vague." (65) Thus Carnap. Insofar as they have a clear meaning, their meaning is empirical, not metaphysical; insofar as they are metaphysical, they are meaningless. I would put the Carnapian argument as follows in terms of the following dilemma:
Either metaphysical grounding (as it occurs in the putative relation between a truth-maker and a truth-bearer) is a causal relation or it is a logical relation. But it is neither. It is not a relation of empirical causation. Truth-maker theorists insist on this themselves. Nor is it a logical relation such as entailment. Logical relations hold between and among truth-bearers; a truth-maker, however, though proposition-like on some theories, is not a truth-bearer. 'Truth-making,' then has neither the meaning of 'causing' nor the meaning of 'entailing.'
Yet, no criterion is specified for any other meaning. Consequently, the alleged 'metaphysical' meaning which the word is supposed to have here in contrast to the mentioned empirical meaning, does not exist. [. . .] The word is explicitly deprived of its original meaning . . . . (65)
The word 'making' is stripped of its empirical meaning, but no new meaning is supplied. The word becomes an "empty shell." (66) The associations and feelings attached to the word used in the old empirical way remain in play. But these do not give meaning to the word used in the new 'metaphysical' way: "it remains meaningless as long as no method of verification can be described." (66)
The same holds for all specifically metaphysical terms. There are one and all "devoid of meaning." (67) Carnap mentions the following: the Idea, the Absolute, the Unconditioned, the Infinite, and "the being of being," which I take to be a reference to Heidegger's das Sein des Seienden, which is better translated as 'the Being of beings.' But also: non-being, thing-in-itself, absolute spirit, objective spirit, essence, being-in-itself, being-in-and-for-itself, the Non-Ego.
These terms are meaningless because empirical truth-conditions of their use cannot be supplied. Hence the alleged statements of metaphysics which contain them are one and all pseudo-statements that are bare of sense and assert nothing. (67)
Perhaps the best response to Carnap and those of his ilk is brutal contradiction: "You're just wrong!" The words you would dismiss as meaningless just obviously have meaning and you're just obviously wrong to think otherwise.
For example, it is clear enough what it means to say that some truth-bearers need truth-makers, that a sentence such as 'Peter is smoking' cannot just be true but is true because of something external to the sentence, something external on the side of the object, not on the side of the subject, i.e., on the side of the one who asserively utters the sentence. And it is clear enough that this use of 'because' is not an empirical-causal use of the term. It is also clear enough what 'in virtue of' and 'making' mean in this context.
Another devastating response to Carnap is the obvious point that his Verifiability Criterion of Cognitive Significance cannot satisfy its own demand. "Every cognitively meaningful statement is either empirically verifiable in principle or a logical/analytic truth" is neither empirically verifiable in principle nor a logical/analytic truth. Therefore, the Verifiability Criterion is cognitively meaningless. So does it then have a merely emotive meaning? Is is a mere suggestion as to what to allow as meaningful? If the latter, then no thank you!
It's an easy rebuttal, but none the worse for that. Sometimes, simplex sigillum veri.
Carnap is to philosophy what a philistine is to the arts: just crude and ignorant . So I dismiss him as a philosophistine. I coined this word ten years or so ago in a polemic against David Stove another philosophistine whose crudity is on shameful display in his The Plato Cult.
My rule is: no polemics in philosophy. But if the other guy starts it . . . . Or the shade of the other guy . . . .
One of the reasons I gave this weblog the title Maverick Philosopher is because I align neither with the analytic nor with the Continental camp. Study everything, I say, and drink from every stream. Reverting to the camp metaphor, when did the camps become two? In dead earnest this occurred when Heidegger burst onto the scene in 1927 with Being and Time. I agree with Peter Simons: "Probably no individual was more responsible for the schism in philosophy than Heidegger." (Quoted in Overgaard, et al., An Introduction to Metaphilosophy, Cambridge UP, 2013, 110.) It is not as if Heidegger set out to split the mainstream whose headwaters were in Franz Brentano into two tributaries; it is just that he started publishing things that the analytic types, who had some sympathy for Heidegger's main teacher Husserl, could not relate to at all.
If I were were to select two writings that best epitomize the depth of the Continental-analytic clash near the time of its outbreak, they would be Heidegger's 1929 What is Metaphysics? and Carnap's 1932 response, "On the Overcoming of Metaphysics Through the Logical Analysis of Language." (In fairness to Carnap, let us note that his Erkenntnis piece is more than a response to Heidegger inasmuch as it calls into question the meaningfulness of all metaphysics.)
To nail my colors to the mast, I take the side of Heidegger in his dispute with Carnap and I heartily condemn the knee-jerk bigotry of the thousands upon thousands of analytic types who mock and deride Heidegger while making no attempt to understand what he is about. The cynosure of their mockery and derision is of course the notorious sentence
Das Nichts selbst nichtet. (GA IX, 114) The Nothing itself nihilates.
This is the line upon which the analytic bigots invariably seize while ignoring everything else: its place in the essay in question and the wider context, that of Being and Time and other works of the early Heidegger, not to mention the phenomenological, transcendental, existential, life-philosophical, and scholastic sources of Heidegger's thinking.
Now, having called them knee-jerk bigots and having implied what is largely true, namely that the analytic Heidegger-bashers are know-nothings when it comes to Heidegger's philosophical progenitors, and thus having paid them back in their own coin, I will now drop all invective and patiently try to explain how and why Heidegger is not talking nonsense in the essay in question. This will require a series of posts. It will also require some attention and open-mindedness on the part of the reader as well as some familiarity with the two essays in question.
Heidegger's Alleged Violation of Logical Syntax
For Carnap it is obvious that existence and nonexistence are purely logical notions, more precisely, logico-syntactic notions. The sentence 'Cats exist,' for example, does not predicate existence of individual cats. It says no more than 'Something is a cat.' But then 'Cats do not exist' says no more than 'Nothing is a cat.' This sentence in turn is equivalent to 'It is not the case that something is a cat.'
'Nothing,' then, is not a name, but a mere bit of logical syntax. Carnap calls it a "logical particle." (71) And the same goes for 'something.' If I met nobody on the trail this morning, it does not follow that I met somebody named 'nobody.' (Bad joke: I say I met nobody, and you ask how he's doing.) If nothing is in my wallet, that is not to say that there is something in my wallet named 'nothing.' It is to say that:
It it not the case that something is in my wallet It is not the case that, for some x, x is in my wallet For all x, x is not in my wallet ~(∃x)(x is in my wallet) (x) ~(x is in my wallet).
The above are equivalents. It should be obvious then, that in its mundane uses 'nothing' is not a name but a logico-syntactic notion that can be expressed using a quantifier (either universal or particular) and the sign for propositional negation. By a mundane use of 'nothing' I mean a use that presupposes that things exist. Thus when I assert that nothing is in my pocket, I presuppose that things exist and the content of my assertion is that no one of these existing things is in my pocket. (Don't worry about the fact that it is never strictly true that there is nothing in my pocket given that there is air, lint, and space in my pocket.)
I think we can all (including Heidegger) agree that in their mundane uses, sentences of the form 'Nothing is F' can be translated, salva significatione, into sentences of the form 'It is not the case that something is F' or 'Everything is not F.' The translations remove 'Nothing' from subject position and by the same stroke remove the temptation to construe 'nothing' as a name. Not that Heidegger ever succumbed to that temptation.
But now the question arises whether every use of 'nothing' fits the deflationary schema. Is every meaningful use of 'nothing' the use of a logical particle? Consider ex nihilo, nihil fit, 'Out of nothing, nothing comes.' The second occurrence of 'nothing' readily submits to deflation, but not the first. Suppose we write
It is not the case that something comes from nothing.
This removes the quantificational use of 'nothing' in 'Out of nothing, nothing comes' but leaves us with a 'substantive' use. Of course, 'nothing' cannot refer to or name any being or any collection of beings. That is perfectly evident. And Heidegger says as much. But 'nothing' does appear to refer to, or name, the absence of every being. The thought is:
Had there been nothing at all, it is not the case that something could have arisen from it.
The 'at all' is strictly redundant: it merely serves to remind the reader that 'nothing' is being used strictly. Now could there have been nothing at all? Is it possible that there be nothing at all? More importantly for present purposes: Is this a meaningful question? 'Possibly, nothing exists' is meaningful only if 'Nothing exists' is meaningful. So consider first the unmodalized
There is nothing at all
or
Nothing exists.
These are perfectly meaningful sentences. That is not to say that they are true, nor is it to say that they are possibly true. Suppose they are not possibly true. Then they are necessarily false. But if necessarily false, then false, and if false, then meaningful. For meaningfulness is a necessary condition of having a truth-value. 'Nothing exists,' then, is a meaningful sentence, and this despite the fact that 'nothing' cannot here be replaced by a phrase containing only a quantifier and the sign for negation.
For Carnap, however, the above are meaningless metaphysical pseudo-sentences because they violate logical syntax. If you try to translate the second sentence into logical notation, into what Carnap calls a "logically correct language"(70) you get a syntactically meaningless string:
~(∃x)(x exists).
This is meaningless because 'exists' cannot serve as a first-level predicate in a logically correct language. Existence is not a property of individuals. 'Exist(s)' is a quantifier, a bit of logical syntax, not a name of a property or of any entity. Therefore, 'Nothing exists' is as syntactically meaningless as the ill-formed formula
~(∃x)(∃x(. . . x . . .)).
Two Interim Conclusions
The first is that Heidegger commits no schoolboy blunder in logic. He does not think that a use of 'Nothing is in the drawer' commits one to the existence of something in the drawer. He cannot be charitably read as assuming that every use of 'nothing' is a referring use. The second conclusion is that Carnap has not shown that every occurrence of 'nothing' can be replaced by a phrase containing a quantifier and the sign for negation. He has therefore not shown that a sentence like 'Nothing exists' is a syntactically meaningless pseudo-sentence.
Heidegger Partially Vindicated
But now the way is clear to ask some Heidegger-type questions.
I showed above that 'nothing' has meaningful uses as a substantive, uses that cannot be eliminated by the Carnap method. And I suggested that 'nothing' could name the total absence of all beings. If this total absence is a possibility, as it would be if every being is a contingent being, then Nothing (das Nichts) would have some 'reality,' if only the reality of a mere possibility. It could not be dismissed as utterly nichtig or nugatory. Nor could questions about it be so dismissed.
One question that Heidegger poses concerns the relation of negation (Verneinung) as a specific intellectual operation (spezifische Verstandeshandlung) to Nothing:
Gibt es das Nichts nur, weil es das Nicht, d. h. die Verneinung gibt? Oder liegt es umgekehrt? Gibt es die Verneinung und das Nicht nur, weil es das Nichts gibt? (GA IX, 108)
Is there Nothing only because there is the Not and negation? Or is it the other way around? Is there negation and the Not only because there is Nothing?
I grant that with questions like these we are at the very limit of intelligibility, at the very boundary of the Sayable. But you are no philosopher if you are not up against these limits and seeking, if possible, to transcend them.
One source of its appeal is that it reinstates much of what was ruled out as cognitively meaningless by logical positivism but without rehabilitating the commitments of old-time metaphysics. Permit me to explain. (My ruminations are in part inspired by Ernest Gellner, to give credit where credit is due.)
Crudely put, as befits a crude philosophy, logical positivism is just Hume warmed over. The LPs take his famous two-pronged fork and sharpen the tines. Hume spoke of relations of ideas and matters of fact, and consigned to the flames anything thing that was not one or the other. In the Treatise of Human Nature, he spoke of "school metaphysics and divinity" as deserving of such rude treatment. Since Hume's day, old-time metaphysics and theology have had a forking hard time of it.
The LPs spoke of two disjoint classes of statements and maintained that every cognitively meaningful statement must be a member of the one or the other. The one class contains the truths of logic and mathematics and such analytic statements as 'Every cygnet is a swan' all interpreted as true by convention. The other class consists of statements empirically verifiable in principle. Any statement not in one of these two disjoint classes is adjudged by the LPs to be cognitive meaningless. Thus the aesthetic statement, 'The adagio movement of Beethoven's Ninth exceeds in beauty anything Bruckner wrote' is by their lights not false, but cognitively meaningless, though they generously grant it some purely subjective emotive meaning. And the same goes for the characteristic statements one finds in theology, metaphysics, and ethics. Such statements are not false, but meaningless, i.e., neither true nor false.
Imagine a debate between a Muslim and a Christian. Muslim: "God is one! There is no god but God (Allah)!" Christian: "God is triune (three-in-one)." For an LP, the debate is meaningless since theological assertion and counter-assertion are meaningless. The assertions are neither analytic nor empirically verifiable. Or consider a debate between two Christians. They are both Trinitarians: there is one God in three divine Persons. But the man from Rome maintains that the Holy Ghost proceeds from the Father and the Son (filioque) while the man from Constantinople maintains that the Holy Ghost proceeds directly from the Father. For an LP, this debate about the procession of Persons is cognitively meaningless. I chose these examples to show how attractive LP is. For many of you will be inclined to think of these debates as in some sense meaningless. "How could one know one way or the other?" Many of you will be inclined to want to tie meaningfulness to empirical verifiability. Nevertheless, Logical Positivism is untenable. But that is not my present point.
My present point concerns the appeal of OLP. The OL boys weren't out to resurrect metaphysics. They took on board the anti-metaphysical animus of the LPs. But their approach allowed the salvaging of ways of talking that the LPs had no interest in preserving. Religious language is a key example. So what I am contending is that one source of the appeal of OL philosophy was that it allowed religious talk and thus religion itself to be saved from the forking accusation of meaninglessness. But it did this without crediting old-time metaphysics. You can see why that would appeal to a lot of people. To explain this properly would take a lot of scribbling.
But the central idea is that religion is a form of life and a language game, a self-contained language game that needs no justification ab extra. Hence it needs no justification from metaphysics or philosophy generally. It is in order as it is -- to use a characteristically Wittgensteinian turn of phrase. By the same token, religion cannot be attacked from the side of philosophy. It is an island of meaning unto itself, and is insofar forth insulated from criticism. (L. insula, ae = island.) Nor can it come into conflict with science or be debunked by science. Within the religious language game there are valid and invalid moves, things it is correct and incorrect to say; but the langauge game itself is neither correct nor incorrect. It just is. Religion is a groundless system of belief, a system of belief that neither needs nor is capable of justification. Since I reject both LP and OLP, I am not endorsing this view of religion. I am merely explaining one of the reasons why people are attracted to OLP: it allows them to practice a religion while ignoring both the threat from traditional philosophy (which demands the justification of key religious tenets) and the the threat of positivism which makes positive science the ultimate arbiter of reality.
A while back I came across Ernest Gellner's Words and Things (unrevised ed., 1963). It is jam-packed with insights. Here is an example:
Linguistic Philosophy [O. L. philosophy] absolutely requires and presupposes [Logical] Positivism, for without it as a tacit premiss, there is nothing to exclude any metaphysical interpretation of the usages that are to be found, and allegedly "taken as they are," in the world. (p. 86)
Exactly right. For if the anti-metaphysics of logical positivism is not presupposed, how can the O.L. philosopher rule out as meaningless metaphysical ways of talking? People talk in all sorts of ways, not all of them mundane. People talk metaphysics for example. I do it all the time, and it certainly seems to me and some of my interlocutors that I am talking sense. For example, I say things like, 'Existence is a necessary condition of property-possession: nothing has properties unless it exists' and there are people who understand me.
Suppose out in the desert there is a little commune of Bradleyans. Their form of life involves playing a language game in which words like 'internal relation,' 'external relation,' 'Absolute,' 'appearance,' and others have well-defined functions. If meaning is use, these words have meaning because they have a use in this community. How can it be said that language has gone on holiday in a case like this? How distinguish holiday from workaday uses of language?
To make the distinction one has to just assume something like the positivistic stricture on metaphysics. On has to just assume that some language games are meaningless. But there is no basis for this distinction if one takes the uses of words as the source of their meaning.
