هویت و تبعیض (سری نظریه فلسفی)

When do two experiences have the same subjective character? What unifies the life of a person? How can animals be grouped into species? Are Latin and Italian different stages of the same language? Could HMS Victory have been made of different planks and still be the same ship? Timothy Williamson argues that these and other questions give rise to philosophical problems with the same underlying structure. In each case, common sense assumptions lead to slippery slope paradoxes. This book proposes a new and unified resolution to these problems, based on techniques from mathematical logic. It requires positions to be taken up on current controversies about vagueness, observation and necessity; the work of philosophers such as Michael Dummett, Crispin Wright, Nathan Salmon and Graeme Forbes is discussed. "Identity" addresses in an original and rigorous way the necessity of discrimination and the thresholds which determine the approximate criteria of identity. Identity and Discrimination This updated edition of Identity and Discrimination , first published in 1990 and the first book by well-known philosopher Timothy Williamson, is now reissued with the inclusion of significant new material. This major work influential in philosophy of perception and the theory of vagueness continues in an original and rigorous way to highlight the necessity of discrimination and the thresholds which determine the approximate criteria of identity. Williamsons proposal for an original and rigorous theory links identity, a relation central to metaphysics, and indiscriminability, a relation central to epistemology. He provides a distinctive cognitive account of the nature of discrimination, with important applications to the philosophy of perception and the theory of vagueness. The book pioneers the use of epistemic logic to solve the notorious paradoxes of indiscriminability, and develops the application of techniques from mathematical logic to understand issues about identity over time and across possible worlds.
