{"product_id":"9780674042490","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":"Harvard University Press","offers":[{"title":"Default Title","offer_id":47105297219824,"sku":"9780674042490","price":28.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9780674042490","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
