For this second edition, Seymour has written a new introduction and has added a new retrospective essay.

Ernst Cassirer: Scientific Knowledge and the Concept of Man by Seymour W. Itzkoff is currently one of the few books available in the English language that discusses the philosophy of twentieth-century German philosopher Ernst Cassirer. Itzkoff's study brings Cassirer's perspective directly into the contemporary debate over the evolution of human thought and its relationship to animal life. Further, Itzkoff places Cassirer directly in the context of recent philosophical thought, arguing for the importance of his Kantian perspective, a significance that is amply vindicated by the current interest in Cassirer's ideas.
