It is difficult at the best of times to render texts in the history of philosophy so that they speak to present-day philosophical concerns; even more so when one is working with materials produced in the Middle Ages. But this book achieves it. Klima is as comfortable in the world of contemporary philosophical logic and metaphysics as he is among fourteenth-century practitioners of the logica moderna, with the result that he is able to present Buridanian nominalism to modern readers in a way that loses very little in translation. The Buridan who emerges in these pages one could easily imagine having as a discussion-partner - and a formidable one at that.

An admirable book that takes on an immensely difficult subject matter. What is more, it proceeds with the kind of precision and clarity that allows any serious reader the opportunity to learn from it and reach a high level of understanding.

This is a marvelous book, a 'must read' for anyone interested in understanding the philosophical debates of the later Middle Ages and a useful book for contemporary philosophers who will find in it a sophisticated articulation of a philosophical position well able to provide perspective on a number of contemporary debates. It is exceptionally well-written, clear, and insightful.
