Metaphysics is the branch of philosophy that deals with the question of existence and the nature of reality. Reprinted here are seventeen texts offering a broad range of different perspectives. Included are Henri Bergson's important book, Time and Free Will, in which he makes a distinction between the concept and the experience of time; Appearance and Reality which expresses Francis Herbert Bradley's central work in idealist metaphysics; and Brand Blanshard's writing on Reason and Analysis marking the fruition of his 1959 Carus lectures before the American Philosophical Association.
