Logics and Languages

This book, originally published in 1991, sets forth the assumptions about thought and language that made falsehood seem so problematic to Plato and his contemporaries, and expounds the solution that Plato finally reached in the Sophist. Free from untranslated Greek, the book is accessible to all studying ancient Greek philosophy.

Originally published in 1973, this book shows that methods developed for the semantics of systems of formal logic can be successfully applied to problems about the semantics of natural languages; and, moreover, that such methods can take account of features of natural language which have often been thought incapable of formal treatment, such as vagueness, context dependence and metaphorical meaning.

Parts 1 and 2 set out a class of formal languages and their semantics. Parts 3 and 4 show that these formal languages are rich enought to be used in the precise description of natural languages.

Appendices describe some of the concepts discussed in the text.
