"Philosophical Reasoning is a probing and commanding study of the methodology of philosophical inquiry. It is an excellent book on the difficult subject of how one should philosophize and what we can reasonably expect of philosophy, and a breath of fresh air falling between the extremes of philosophy as natural science and philosophy as the purely a priori. A very intriguing, articulate and convincing story of the nature of an art Rescher has practiced so well for so long for the benefit of so many. I strongly recommend it." Robert Almeder, Georgia State University "Philosophy aims at rationally constructed comprehensiveness, now more collectively/dialectically and less individually/reflectively than in the past. So argues Nicolas Rescher in this systematic defense of system. If philosophical about their practice, philosophers who pick up this book won't easily put it down, even if in the end they disagree." Ernest Sosa, Brown University "What makes the book such a pleasure to read is that it combines the precision and thoroughness of a master philosopher with a writing style that makes for easy reading. This is a book which both novices and experts should read to help both understand the nature of their enterprise better." Philosophy in Review
