Nils Kürbis delves into three approaches that have been proposed to address this challenge: defining negation in terms of metaphysical incompatibility, treating negation as an undefinable primitive, and defining negation in terms of a speech act of denial. He meticulously examines each of these approaches and concludes that they fall short in adequately capturing the essence of negation.\u003cbr\u003e\u003cbr\u003eKürbis argues that proof-theoretic semantics, traditionally focused on truth, must also incorporate a notion of falsity to fully understand the nature of negation. He presents a novel system of natural deduction that incorporates both truth and falsity, offering fresh perspectives on negation, denial, and falsity. This book will be of significant interest to readers engaged in logic, metaphysics, and the philosophy of language, as it sheds light on these fundamental concepts and provides new insights into their intricacies.\u003c\/p\u003e\u003cp\u003e\n                            \u003cstrong\u003eWeight\u003c\/strong\u003e: 546g\n                            \u003cbr\u003e\u003cstrong\u003eDimension\u003c\/strong\u003e: 168 x 243 x 22 (mm)\n                            \u003cbr\u003e\u003cstrong\u003eISBN-13\u003c\/strong\u003e: 9781108716727\n                            \n                          \u003c\/p\u003e","brand":"NilsKurbis","offers":[{"title":"Paperback \/ softback","offer_id":44095065686266,"sku":"9781108716727","price":30.46,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0522\/4297\/2845\/products\/2eaec410a1a7b57a57f5005981bcffc6.jpg?v=1639717699","url":"https:\/\/shulphink.com\/products\/proof-and-falsity-a-logical-investigation-1","provider":"Shulph Ink","version":"1.0","type":"link"}
