Paul Weiss is Heffer Professor of Philosophy at the Catholic University of America.

This is a very wise book. Though Weiss is writing about human nature, he is ever the metaphysician who can bring the broadest of categories to bear on topics such as necessity and freedom, habit, emotion, motivation, spontaneity, pain and self-expression. He leaves no view unexamined, is not afraid to criticize accepted solutions, and is always suggestive. First published a generation ago, this book has weathered well the intervening years. It is amazing how little the contemporary idiom of discourse has changed. Part is due to the timeless character of the questions asked and part to Weiss's time-transcending vision. -- Jude P. Dougherty, Catholic University of America Nature and Man is the book in which Paul Weiss transformed Whitehead's speculative cosmology into a genuine metaphysical revolution. Its careful distinction between the 'inner' and 'outer' is the key to 20th century pluralism. -- Robert Neville, SUNY, Stony Brook Nature and Man is the book in which Paul Weiss transformed Whitehead's speculative cosmology into a genuine metaphysical revolution.
