The Cartesian Dream Argument and an Austinian Contrast Argument

J. L. Austin, in a footnote to p. 49 of Sense and Sensibilia (Oxford, 1962), writes of ". . . the absurdity of Descartes' toying with the notion that the whole of our experience might be a dream." In the main text, there is a sort of argument for this alleged absurdity. The argument may be set forth as follows:

Contrast Arguments

One of the weapons in the arsenal of Ordinary Language and other philosophers is the contrast argument. Such arguments are used to show the meaninglessness of certain terms, typically, the terms we metaphysicians like to bandy about. One type of contrast argument has the form:

1. If a term T is meaningful, then there are items to which T does not apply.
2. There are no items to which T does not apply.
Ergo
3. T is not meaningful.
