The work of Aristotle (384-322 bc) is considered to be one of the greatachievements of the ancient world, and is a foundation of both Westernand Middle Eastern philosophy and science. Although Aristotle leftsignificant material on almost all branches of learning, what hassurvived is a somewhat disorganized collection of notes and lectures.Moreover, the centuries of interpretation across various epochs andcultures tend to cloud our understanding of him. 

Thomas Kiefer breaks through this cloud of interpretation and providesan organized account of one key part of Aristotle's philosophy, namelyhis theory of knowledge. This theory concerns what is knowledge, what wecan know, and how we can do so. Kiefer's book is the first work thattakes this theory as its sole focus and reconstructs it systematically. 
Kiefer's work throughout provides many newinterpretations of key parts of Aristotle's philosophy, including an unnoticed -but crucial- distinction between knowledge in general and knowledge for us, the differences between his semantic and psychological requirements for knowledge, and'nous', which is perhaps the most obscure notion in Aristotle's work.He also concludes with a summary of Aristotle's theory in the terms andstyle of contemporary epistemology. Kiefer's work should be ofinterest to anyone involved in the history of philosophy or contemporaryepistemology.
