Abstract

The editors tell us this book is an outgrowth of their course in philosophical arguments. It contains both readings from traditional sources, and new material especially for this book. It is thus of interest as a potential text, as a source book, and for its original contributions. To consider it first as a text, it would be a challenging and valuable choice for sophisticated students. As a source-book, it is a good anthology of hard-core arguments on seven metaphysical topics. Authors selected include Aristotle, Plato, Church Fathers, Rationalists, Locke and Hume, Bradley and Moore, Kant, Frege, Carnap, C. I. Lewis, Russell, and others. Selections run from a page or two to 16-page Hume excerpts. The last section, on The Nature of Metaphysics, contains essays newly written for this volume by A. J. Ayer, Brand Blanshard, John Passmore, and M. Lazerowitz. Other new material elsewhere in the book includes Alice Ambrose on Wittgenstein, and the introduction by W. E. Kennick. The latter suggests that in metaphysics there are arguments but no proofs, and that metaphysics has four curious characteristics: its disputes are never resolved; in these disputes the array of experts on each side is likely to be equally impressive; antinomies seem unavoidable; and metaphysics frequently conflicts with common sense. Ayer's article is called "Metaphysics and Common Sense." Using Carnap's distinction of "internal" and "external" questions, he finds metaphysical questions to be external. His explanation of what these are and why anyone would wish to raise them yields three legitimate ways in which metaphysics can add to our understanding of the world, and concludes that "it would be a mistake to forego the more imaginative kinds of conceptual exploration." In both tone and content this essay is a surprise for readers who know earlier work by Ayer. Passmore attempts to correct the popular tendency to confuse the philosopher with the sage. He places metaphysics, mathematics, and empirical science within "rational discussion": each is speculation, each has its characteristic control procedure. Blanshard's article attempts to defend metaphysics against criticisms such as those made by Dewey, Wittgenstein, and Freud. Lazerowitz treats the thesis that "metaphysics works by unseen paradoxes."--M. B. M.
