Abstract

This paper is about the claim that, necessarily, a subject who can think that a is F must also have the capacities to think that a is G, a is H, a is I, and so on (for some reasonable range of G, H, I), and that b is F, c is F, d is F, and so on (for some reasonable range of b, c, d). I set out, and raise objections to, two arguments for a strong version of this claim (Gareth Evans' generality constraint). I present a new argument for a weaker version of the claim, and sketch some directions of enquiry which this new argument opens up
