{"product_id":"elementary-logic-book-willard-van-orman-quine-9780674244511","title":"Elementary Logic","description":"Now much revised since its first appearance in 1941, this book, despite its brevity, is notable for its scope and rigor. It provides a single strand of simple techniques for the central business of modern logic. Basic formal concepts are explained, the paraphrasing of words into symbols is treated at some length, and a testing procedure is given for truth-function logic along with a complete proof procedure for the logic of quantifiers. Fully one third of this revised edition is new, and presents a nearly complete turnover in crucial techniques of testing and proving, some change of notation, and some updating of terminology. The study is intended primarily as a convenient encapsulation of minimum essentials, but concludes by giving brief glimpses of further matters.","brand":"WoB","offers":[{"title":"GB \/ VERY_GOOD \/ INTERNAL","offer_id":49528884592913,"sku":"GOR003519521","price":10.0,"currency_code":"USD","in_stock":true},{"title":"GB \/ GOOD \/ INTERNAL","offer_id":49653059256593,"sku":"GOR002813135","price":11.99,"currency_code":"USD","in_stock":false},{"title":"US \/ VERY_GOOD \/ SBYB","offer_id":49889247625489,"sku":"CIN0674244516VG","price":6.18,"currency_code":"USD","in_stock":false},{"title":"US \/ GOOD \/ SBYB","offer_id":50171490894097,"sku":"CIN0674244516G","price":5.76,"currency_code":"USD","in_stock":false},{"title":"GB \/ WELL_READ \/ INTERNAL","offer_id":50869696528657,"sku":"GOR003264914","price":10.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/0674244516.jpg?v=1751198835","url":"https:\/\/www.worldofbooks.com\/products\/elementary-logic-book-willard-van-orman-quine-9780674244511","provider":"World of Books ","version":"1.0","type":"link"}
