Gregory Vlastos (1907-1991) was one of the twentieth century's most influential scholars of ancient philosophy. Over a span of more than fifty years, he published essays and book reviews that established his place as a leading authority on early Greek philosophy. This title collects Vlastos' essays on Presocratic philosophy. "This well-edited collection of thirty-six essays is . . . a great boon to students of pre-Aristotelian philosophy. . . . The clarity of argument allows for fruitful use by anyone with a keen interest in ancient thought."
