In the appendix to Psychosemantics, entitled ‘Why There Still has to be a Language of Thought,’ Jerry Fodor offers several arguments for the language of thought thesis. The LOT, as articulated by Fodor, is a thesis about propositional attitudes. It comprises the following two claims: (1) propositional attitudes are relations to meaning-bearing tokens — for example, to believe that P is to bear a certain relation to a token of a symbol which means that P; and (2) the representational tokens in question are quasi-linguistic — in particular, they have the constituent structure appropriate to a language.

3 Each attitude type is construed as a computational relation to a symbol token; so believing will be one computational relation, and desiring another.
