These apparently ssimple questions have perplexed philosophers for thousands of years, but discussion of them was transformed by the German philosopher Gottlob Frege (1848-1925).\u003cbr\u003eFrege (pronounced Fray-guh)believed that arithmetic and all mathematics are derived from logic, and to prove this he developed a completely new approach to logic and numbers. Joan Weiner presents a very clear outline of Frege's life and ideas, showing how his thinking evolved through successive books and articles.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eBinding Type:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Open Court\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 02\/01\/2005\u003cbr\u003e\u003cb\u003eISBN:\u003c\/b\u003e 9780812694604\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 176\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.60lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 8.98h x 6.12w x 0.52d","brand":"Joan Weiner","offers":[{"title":"Default Title","offer_id":36644411441308,"sku":"9780812694604","price":22.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0473\/0804\/6492\/products\/img_fa47e0e0-6d0d-4b29-bae7-5996863e56d0.jpg?v=1603858573","url":"https:\/\/pastforward.org\/products\/frege-explained-9780812694604","provider":"Past Forward","version":"1.0","type":"link"}
