{"product_id":"natural-deduction-dag-prawitz-9780486446554","title":"Natural Deduction: A Proof-Theoretical Study","description":"Prawitz''s theories form the basis of intuitionistic type theory, and his inversion principle constitutes the foundation of most modern accounts of proof-theoretic semantics. The proof-theoretical system represents a simpler and more illuminating method than alternative approaches, and this volume offers a succinct, coherent illustration of its applications to natural deduction. 1965 edition.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Dag Prawitz\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 0486446557\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9780486446554\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Dover Publications\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 02\/24\/2006\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 128\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.30lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 7.68h x 5.98w x 0.28d","brand":"Dag Prawitz","offers":[{"title":"Paperback","offer_id":44045642760447,"sku":"9780486446554","price":9.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_16df4a32-d783-4e17-9900-d9748d8e4bb2.jpg?v=1684979894","url":"https:\/\/www.whiterainbookhouse.com\/products\/natural-deduction-dag-prawitz-9780486446554","provider":"WR Book House","version":"1.0","type":"link"}
