Categories

are either cla es under which all our Notions of things may be grouped, or cla es under which all our Thoughts of things may be grouped; the former called Logical, we owe to Aristotle, and the latter called Metaphysical, we owe to Kant. The Logical, so derived, that group our notions, are ten in number: Substance or Being, Quantity, Quality, Relation, Place, Time, Position, Po e ion, Action, Pa ion. The Metaphysical, so derived, that group our thoughts, are twelve in number: (1) as regards quantity , Totality, Plurality, Unity; (2) as regards quality , Reality, Negation, Limitation; (3) as regards relation , Substance, Accident, Cause and Effect, Action and Reaction; (4) as regards modality , Po ibility and Impo ibility, Existence and Nonexistence, Nece ity and Contingency. John Stuart Mill resolves the categories into five, Existence, Co-existence, Succe ion, Causation, and Resemblance.
