Single Idea 22418

[catalogued under 19. Language / C. Assigning Meanings / 9. Indexical Semantics]

Full Idea

I know the truth of the sentence 'I am here now' a priori, but I do not know a priori 'McGinn is in London on 15th Nov 1981'.

Gist of Idea

I can know indexical truths a priori, unlike their non-indexical paraphrases

A Reaction

I'm not convinced that I can grasp the concepts of 'here' and 'now' (i.e. space and time) by purely a priori means. But he certainly shows that you can't glibly dismiss indexicals by paraphrasing them in that way.
