His own choices of terms have tended to beguile his interpreters. Some down-play the importance of the terms. Jeroen van Rijen, for example, argues that the ‘striking carelessness of [Aristotle’s use of terms in constructing counter-examples] witnesses the relative unimportance of this part of the theory’s systematics’. (van Rijen 1989, p. 201) Some interpreters bemoan Aristotle’s use of ordinary language terms altogether, not because of a carelessness about them, but because of a conviction that terms simply do not belong in any formal logic, that they are inappropriate in formal logic.
