Foundations of Logical Consequence

Author: Colin R. Caret
Publisher: OUP Oxford

Genre: Philosophy

Logical consequence is the relation that obtains between premises and conclusion(s) in a valid argument. Orthodoxy has it that valid arguments are necessarily truth-preserving, but this platitude only raises a number of further questions, such as: how does the truth of premises guarantee the truth of a conclusion, and what constraints does validity impose on rational belief? This volume presents thirteen essays by some of the most important scholars in the field of philosophical logic. The essays offer ground-breaking new insights into the nature of logical consequence; the relation between logic and inference; how the semantics and pragmatics of natural language bear on logic; the relativity of logic; and the structural properties of the consequence relation.

Advances in Proof Theoretic Semantics

Author: Thomas Piecha
Publisher: Springer
ISBN: 9783319226866
Release Date: 2015-10-24
Genre: Philosophy

This volume is the first ever collection devoted to the field of proof-theoretic semantics. Contributions address topics including the systematics of introduction and elimination rules and proofs of normalization, the categorial characterization of deductions, the relation between Heyting's and Gentzen's approaches to meaning, knowability paradoxes, proof-theoretic foundations of set theory, Dummett's justification of logical laws, Kreisel's theory of constructions, paradoxical reasoning, and the defence of model theory. The field of proof-theoretic semantics has existed for almost 50 years, but the term itself was proposed by Schroeder-Heister in the 1980s. Proof-theoretic semantics explains the meaning of linguistic expressions in general and of logical constants in particular in terms of the notion of proof. This volume emerges from presentations at the Second International Conference on Proof-Theoretic Semantics in Tübingen in 2013, where contributing authors were asked to provide a self-contained description and analysis of a significant research question in this area. The contributions are representative of the field and should be of interest to logicians, philosophers, and mathematicians alike.

Thomas Reid on Mind Knowledge and Value

Author: Rebecca Copenhaver
Publisher: OUP Oxford
ISBN: 9780191053405
Release Date: 2015-08-06
Genre: Philosophy

This volume offers a fresh view of the work of Thomas Reid, a leading figure in the history of eighteenth-century philosophy. A team of leading experts in the field explore the significance of Reid's thought in his time and ours, focusing in particular on three broad themes: mind, knowledge, and value. Together, they argue that Reid's philosophy is about developing agents in a rich world of objects and values, agents with intellectual and active powers whose regularity is productive. Though such agents are equipped at first with rudimentary abilities, those abilities are responsive. Our powers consist in a fundamental and on-going engagement with the world, a world that calls on us to be flexible, sensitive, astute, and ultimately, practical. Thomas Reid on Mind, Knowledge, and Value represents both the vitality of Reid's work, and the ways in which current philosophers are engaging with his ideas.

Emergence in Mind

Author: Graham Macdonald
Publisher: Oxford University Press
ISBN: 9780199583621
Release Date: 2010-04-29
Genre: Philosophy

There have long been controversies about how minds can fit into a physical universe. In Emergence in Mind a distinguished group of philosophers discuss whether mental properties can be said to 'emerge' from physical processes. The discussion is extended to cover the role emergence may play in free will and agency, and in the special sciences.

Reclaiming Liberty

Author: M. Bentwich
Publisher: Springer
ISBN: 9781137016683
Release Date: 2012-10-10
Genre: Political Science

Based on a reconstruction of earlier liberal conceptions of liberty (the political theories of John Locke & J.S. Mill), this book stresses the empowering nature of liberal freedom and explains why such a concept of liberty better addresses two key contemporary challenges in liberal theory and praxis: wealth redistribution and multiculturalism.
