This book presents an  investigation of this time-honored problem by means of alethic-deontic  predicate logic. New in this study is the leitmotif of relevance:  is-ought inferences indeed exist, but they are all irrelevant in a  precise logical sense. New proof techniques establish this result for  very broad classes of logics. A profound philosophical analysis of  is-ought bridge principles supplements the logical study. The final  results imply incisive limitations for the justifiability of ethics as  opposed to empirical science.\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9780792344100\"\u003e\u003ch3\u003eAn Investigation in Philosophical Logic\u003c\/h3\u003e\u003c\/div\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9789048147953\"\u003e\u003ch3\u003eAn Investigation in Philosophical Logic\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Hardcover - 9780792344100","offer_id":50827950086,"sku":"9780792344100","price":213.99,"currency_code":"EUR","in_stock":true},{"title":"Softcover - 9789048147953","offer_id":39415518593117,"sku":"9789048147953","price":213.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/f9b873f6-bfe2-4f06-98c1-e84978b52cdf.jpg?v=1772262714","url":"https:\/\/shop.autorenwelt.de\/products\/the-is-ought-problem-an-investigation-in-philosophical-logic-von-g-schurz","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
