{"product_id":"frege-explained","title":"Frege Explained","description":"What is the number one? How can we be sure that 2+2=4? 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.","brand":"Open Court Publishing Co ,U.S.","offers":[{"title":"Default Title","offer_id":54227773784408,"sku":"9780812694604","price":25.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0278\/1295\/4195\/files\/9780812694604_811351be-e6c3-4f26-aa0e-ba80ec1610fc.jpg?v=1765278014","url":"https:\/\/agendabookshop.com\/products\/frege-explained","provider":"Agenda Bookshop","version":"1.0","type":"link"}
