Among the most renowned barriers in philosophy, Hume's Law stands out, asserting that it is impossible to draw normative conclusions from descriptive premises, or in a slogan form: you cannot derive an ought from an is. This barrier has sparked intense controversy, leading to numerous famous counterexamples proposed in the past century. However, it is important to note that there exist other barriers that function as philosophical platitudes: no universal conclusions from particular premises, no future conclusions from premises about the past, and no claims that attribute necessity from premises that merely describe how things happen to be in the actual world.\u003cbr\u003e\u003cbr\u003eBarriers to Entailment presents a comprehensive and unified logical account of five barriers that have played crucial roles in philosophy. Through this work, the author aims to diagnose proposed counterexamples and demonstrate that the case for Hume's Law is as compelling as that for the platitudinous barriers. The first two parts of the book employ techniques from formal logic, presenting them in an accessible manner suitable for readers with a background in first-order model theory, which is often taught in a first-class logic course. Gillian Russell introduces tense, modal, indexical, and deontic formal logics, carefully avoiding unnecessary complexity. Each barrier is interconnected with broader philosophical topics such as universality, time, necessity, context-sensitivity, and normativity. Russell highlights under-recognized connections between these domains, laying the groundwork for further exploration at their intersections.\u003cbr\u003e\u003cbr\u003eIn the final part of the book, the author transposes the formal work to informal barrier theses in the philosophy of language. This transition leads to new insights into the concept of logical consequence and provides fresh perspectives on the nature of entailment. The book offers valuable contributions to the field of logic and philosophy, expanding our understanding of the complexities and limitations of reasoning and inference.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e: 636g\u003cbr\u003e\u003cstrong\u003eDimension\u003c\/strong\u003e: 240 x 166 x 24 (mm)\u003cbr\u003e\u003cstrong\u003eISBN-13\u003c\/strong\u003e: 9780192874733\u003c\/p\u003e","brand":"Prof Gillian K.Russell","offers":[{"title":"Hardback","offer_id":45796468130042,"sku":"9780192874733","price":67.47,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0522\/4297\/2845\/files\/1714143477632_book.jpg?v=1714208535","url":"https:\/\/shulphink.com\/products\/barriers-to-entailment-humes-law-and-other-limits-on-logical-consequence-9780192874733","provider":"Shulph Ink","version":"1.0","type":"link"}
