Translated by E. M. Edghill
The Categories is the first text in Aristotle's logical corpus, the Organon. It introduces the ten categories — substance, quantity, quality, relation, place, time, position, state, action, and affection — that classify everything that can be predicated of a subject. Short, dense, and foundational, it set the agenda for Western metaphysics from Plotinus to Kant and remains the entry point to Aristotle's logical writings.
