"With the sophistic modern and Enlightenment misconceptions about philosophy's nature and history daily crashing and burning around us, Deely's unconventional way of understanding medieval philosophy is like a breath of fresh air amid intellectual smog. This is a great book, the single most important study of medieval thought in half a century or more. It deserves an unbiased hearing by anyone today claiming to be a serious philosopher." -- Peter A.

"Drawing upon the thought of John Poinsot and Charles Pierce, John Deely has opened a distinctively postmodern path to the metaphysics of being, at once illuminating much of this ancient tradition while casting new light upon it in the context of contemporary thought. His treatment notably of St. Thomas is not merely a return to an earlier thinker, but an opening to a different path, at once in profound agreement with St. Thomas and yet heretofore unexplored. This book, thus, not only constitutes a return to a past era, but shows this era in a new light that illuminates as well the contemporary scene." -- Kenneth L. Schmitz
