Wide content and individualist approaches to the individuation of thoughts appear to be incompatible; I think they are not. I propose a criterion for the classification of thoughts which captures both. Thoughts, I claim, should be individuated by their teleological functions. Where teleological function is construed in the standard way - according to the aetiological theory - individuating thoughts by their function cannot produce a classification which is both individualistic and consistent with the principle that sameness of wide content is sufficient for sameness of psychological state. There is, however, an alternative approach to function, the relational theory, which is preferable on independent grounds. A taxonomy of thoughts based on these functions reconciles wide content with individualism. One consequence of individuating thoughts in this way is that intentional content is context sensitive. I discuss some of the implications of context sensitive content.

Brian Loar has argued that the well-known arguments against individualism in the philosophy of mind are insufficient because they rely on the assumption that that-clauses uniquely capture psychological content. He tried to show that this is not the use of that-clauses in philosophical psychology. I argue that he does not succeed in his argument. That-clauses sometimes capture psychological content, if our system of mental ascription is to be workable at all. I argue further that individualism tends to be at odds with a requirement of intersubjective shareability of contents and that Loar is alternative conception of psychological content is beset with difficulties.
