Perhaps everyone who can think has the concept of possibility, but no one understands it. The metaphysical theory of Determinism is a symptom of this lack of understanding, and the inconclusiveness of its opponents' arguments indicates that the lack is universal. In this book, first published in 1968, the author shows that there are a number of different kinds on non-logical possibility, subtly interrelated, each requiring separate explanation. An original contribution to the subject, it is essential reading for all students of philosophy.

This collection of essays on themes in the work of John Locke (1632-1704), George Berkeley (1685-1753), and David Hume (1711-1776), provides a deepened understanding of major issues raised in the Empiricist tradition. In exploring their shared belief in the experiential nature of mental constructs, The Empiricists illuminates the different methodologies of these great Enlightenment philosophers and introduces students to important metaphysical and epistemological issues including the theory of ideas, personal identity, and skepticism. It will be especially useful in courses devoted to the history of modern philosophy.
