Abstract
Renewed interest in the Presocratics of the last few decades has not ignored Heraclitus, and some new and fruitful lines of inquiry are now being pursued. This article on Heraclitus presents a unified Heraclitus who is a thoughtful critic of his predecessors, and keenly interested in the possibility of human understanding. This Heraclitus rejects the Milesian account of a single substance with systematic changes and transformations that guarantee the stability of the whole. He recognizes that his new views will be difficult to understand, but provides hints and lessons to allow his hearer or reader to grasp his philosophical account. Parmenides of Elea, too, has not been ignored by the scholarly community—a number of new interpretations of Parmenides have appeared in the last decade.
