Amazon Synopsis
- What sorts of things are numbers? How is it possible to know about them? And how, in knowing about them, do we thereby have knowledge of features of the material world?
- These questions are almost as old as philosophy itself. In Frege's Conception of Numbers as Objects Crispin Wright defends modernised versions of the responses to them of the great German mathematician and philosopher, Gottlob Frege, who held that numbers are a kind of logical object and that our knowledge about them, and its relevance to the real world, is to be seen as a product of our faculty of logical thought.
- Wright's book re-established Frege's programme on the agenda of contemporary philosophy of mathematics, and this revised and augmented second edition will be required reading for all with interest in the philosophies of mathematics and of language.
