In this insightful and controversial book, Rosen takes a new look at the famous "quarrel" that the moderns have with the ancients, analyzing and comparing ancient philosophers and modern Continental and analytical thinkers from Plato, Descartes, and Kant to Fichte, Nietzsche, and Rorty. He urges that we not dismiss the classical heritage but appropriate it, for this appropriation is an indispensable step in the process of legitimizing our historical experience.
