The Hafner Library of Classics offers a refreshing approach to the study of major Western philosophers through introductory essays by noted scholars that work to enliven the discussion of the human side of great thinkers.

In this addition to the series, the Hafner Library brings one of Spinoza's greatest works back to the focus of readers. Posthumously published, Ethics discusses the nature of God, the mind, the emotions, human bondage to emotion, and the power of understanding.
