ABSTRACT
To the proposal that every mental event kind is correlated to a neural event kind down to the finest grain two very general kinds of objection have been advanced. These objections are deep and powerful, but though they would preclude various versions of the Correlation thesis, there is one important version which they would not preclude, and which is the version the determinist requires to make his case. Those who believe in the possibility of establishing fine-grained correlations between mental events and brain events are often in the grip of an old-fashioned view about the mind, according to which mental events are private happenings in a person's consciousness, whose nature it is to have actually precisely the qualities they appear to have, to occupy space in an odd way, and time in the usual way. The Extramentality thesis is a thesis about the mental language and its imperfect relation to conscious states.
