Aristotle's Modal Logic: Essence and Entailment in the Organon

Aristotle's Modal Logic presents a radically new interpretation of Aristotle's logic by arguing that a proper understanding of the system depends on an appreciation of its connection to the metaphysics. Patterson establishes that there is a fundamental connection between Aristotle's logic of possibility and necessity, and his metaphysics; that this connection extends far beyond the widely recognized tie to scientific demonstration and relates to the more basic distinction between the essential and accidental properties of a subject.
