Frege in Perspective

What is the number one? How do we know that 2 + 2 = 4? These apparently simple questions are in fact notoriously difficult to answer, and in one form or other have occupied philosophers from ancient times to the present. Gottlob Frege's conviction that the truths of arithmetic, and mathematics more generally, are derived from self-evident logical truths formed the basis of a systematic project which revolutionized logic, and founded modern analytic philosophy.Joan Weiner is the author of 'Frege in Perspective' with ISBN 9780801421150 and ISBN 0801421152.
