Summary
I once got into an argument after dinner with my friend Zenon Pylyshyn. The argument concerned the following assertion which Pylyshyn made: ‘cognitive psychology is impossible if there is not a well-defined notion of sameness of content for mental representations’. It occurred to me later that the reasons I have for rejecting this assertion tie in closely with Donald Davidson's well-known interests in both meaning theory and the philosophy of mind. Accordingly, with Zenon's permission and (I hope) forgiveness, I have decided to make my arguments against his assertion the subject of this paper.
Mental representation
Let us consider what goes on in the mind when we think ‘there is a tree over there’, or any other common thought about ordinary physical things. On one model, the computer model of the mind, the mind has a ‘program’, or set of rules, analogous to the rules governing a computing machine, and thought involves the manipulation of words and other signs (not all of this manipulation ‘conscious’, in the sense of being able to be verbalized by the computer). This model, however, is almost vacuous as it stands (in spite of the heat it generates among those who do not like to think that a mere device, such as a computing machine, could possibly serve as a model for something as special as the human mind). It is vacuous because the program, or system of rules for mental functioning, has not been specified; and it is this program that constitutes the psychological theory.
