An Inquiry on Modal Metaphysical Puzzling Possible Worlds


Book Description

The concept of possible worlds is useful because it defines the four modalities – possibility, necessity, contingency, and impossibility – but a challenge lies in defining it. David Lewis’ polemical hypothesis (“genuine modal realism” as it is called) succeeds in it. Lewis’ modal realism stirred controversy because he maintains that a plurality of worlds exists. Some philosophers suggest that the Lewisian view is a violation to the law of parsimony, also known as Ockham’s Razor, i.e. not multiply entities beyond necessity. While avoiding a circular definition, Lewis constructs an inflated ontology. Is it worth it, and if we do not want to assume too many Lewisian worlds, what alternatives remain? Actualist modal realism and modal antirealism are the most relevant alternatives because modal abstentionism simply will not progress in this direction. This study evaluates the theories of possible worlds.

Modality


Book Description

The philosophy of modality investigates necessity and possibility, and related notions—are they objective features of mind-independent reality? If so, are they irreducible, or can modal facts be explained in other terms? This volume presents new work on modality by established leaders in the field and by up-and-coming philosophers. Between them, the papers address fundamental questions concerning realism and anti-realism about modality, the nature and basis of facts about what is possible and what is necessary, the nature of modal knowledge, modal logic and its relations to necessary existence and to counterfactual reasoning. The general introduction locates the individual contributions in the wider context of the contemporary discussion of the metaphysics and epistemology of modality.

Modal Logic as Metaphysics


Book Description

Timothy Williamson gives an original and provocative treatment of deep metaphysical questions about existence, contingency, and change, using the latest resources of quantified modal logic. Contrary to the widespread assumption that logic and metaphysics are disjoint, he argues that modal logic provides a structural core for metaphysics.




On the Plurality of Worlds


Book Description

This book is a defense of modal realism; the thesis that our world is but one of a plurality of worlds, and that the individuals that inhabit our world are only a few out of all the inhabitants of all the worlds. Lewis argues that the philosophical utility of modal realism is a good reason for believing that it is true.




The Philosophy of Philosophy


Book Description

The expanded new edition of one of the most influential and controversial books about the nature of philosophy published in the past several decades The Philosophy of Philosophy presents an original, unified concept of philosophy as a non-natural science. In this provocative work, distinguished philosopher Timothy Williamson challenges widely-held assumptions and clarifies long-standing misconceptions about the methodology and nature of philosophical inquiry. The author rejects the standard narratives of contemporary philosophy developed from naturalism, the linguistic turn, postmodern irony, and other prominent trends of the twentieth century. Viewing the method of philosophy as evolving from non-philosophical pursuits, Williamson provides readers with fresh insight into the “self-image” of philosophy and offers new ways of understanding what philosophy is and how it actually works. Now in its second edition, this landmark volume comprises the original book and the author’s subsequent work. New topics include the recent history of analytic philosophy, assessments of experimental philosophy, theories of concepts and understanding, Wittgensteinian approaches, popular philosophy, naturalism, morally-loaded examples in philosophy, philosophical applications of scientific methods, and many more. This edition features the author’s latest thoughts on a variety of issues, autobiographical reflections, and replies to critics. Proposes an alternative narrative about the nature of philosophy Argues that the common assumption of philosophical exceptionalism is false Highlights the similarities between philosophy and the other sciences in both methodology and subject matter Explores why contemporary philosophy has failed to articulate an adequate methodology Emphasizes increasing the methodological standards of reasoning in philosophy The Philosophy of Philosophy, Second Edition remains essential reading for philosophers, scholars, graduate and advanced undergraduate students in philosophy, and other readers with a sustained interest in the method and rationale of the doing of philosophy.




Naming and Necessity


Book Description

If there is such a thing as essential reading in metaphysics or in philosophy of language, this is it. Ever since the publication of its original version, Naming and Necessity has had great and increasing influence. It redirected philosophical attention to neglected questions of natural and metaphysical necessity and to the connections between these and theories of reference, in particular of naming, and of identity. From a critique of the dominant tendency to assimilate names to descriptions and more generally to treat their reference as a function of their Fregean sense, surprisingly deep and widespread consequences may be drawn. The largely discredited distinction between accidental and essential properties, both of individual things (including people) and of kinds of things, is revived. So is a consequent view of science as what seeks out the essences of natural kinds. Traditional objections to such views are dealt with by sharpening distinctions between epistemic and metaphysical necessity; in particular by the startling admission of necessary a posteriori truths. From these, in particular from identity statements using rigid designators whether of things or of kinds, further remarkable consequences are drawn for the natures of things, of people, and of kinds; strong objections follow, for example to identity versions of materialism as a theory of the mind. This seminal work, to which today's thriving essentialist metaphysics largely owes its impetus, is here published with a substantial new Preface by the author.

Logical Dynamics of Information and Interaction


Book Description

This book develops a view of logic as a theory of information-driven agency and intelligent interaction between many agents - with conversation, argumentation and games as guiding examples. It provides one uniform account of dynamic logics for acts of inference, observation, questions and communication, that can handle both update of knowledge and revision of beliefs. It then extends the dynamic style of analysis to include changing preferences and goals, temporal processes, group action and strategic interaction in games. Throughout, the book develops a mathematical theory unifying all these systems, and positioning them at the interface of logic, philosophy, computer science and game theory. A series of further chapters explores repercussions of the 'dynamic stance' for these areas, as well as cognitive science.
