Abstract
In this paper I argue that the logos, the primary object of knowledge in Heraclitus’ epistemology, is a unity both as an object of knowledge and as an instance of being rather than becoming. Section I begins with discussions of knowledge and Heraclitus’ conception of logos; section II is concerned with knowledge and unity. The two later sections of the paper explore the consequences of the account I attribute to Heraclitus: section III considers being, unity, and change; and section IV discusses Heraclitus’ views of knowledge and sense perception.
