<idealism, ockhamism, empiricism, epistemology, rationalism> on Locke's conception ideas are the contents with which minds are "furnished" (as he puts it). From "simple ideas" (e.g., or red, of round, of sweet) furnished by sense-perception the mind constructs "complex ideas" (e.g., of apple). Conception being nothing but this compounding of sense based ideas, and reasoning being nothing but transitions between ideas thus compounded, all knowledge -- Locke maintains -- derives ultimately from sensory experience. See also: empiricism, impressions.
