David Weissman is Professor of Philosophy at City College of New York. He is the author of Intuition and Ideality, also published by SUNY Press.

"It is without any doubt Weissman's most mature, richest work and builds nicely on his earlier volumes, especially Intuition and Ideality. It is downright delightful to see a careful thinker unabashedly engaged in the great speculative enterprise of metaphysics and to observe with what skill he avoids the minefields that had blown up his predecessors. Hypothesis and the Spiral of Reflection is an important book by a rapidly developing major voice in this country." — John Lachs, Vanderbilt University"Written with clarity and elegance, it is a well-argued defense of an important alternative to both analytic philosophy and phenomenology." —Panayot Butchvarov, The University of Iowa
