Plato's views on change and contrariety arise from concerns about definition and explanation in the aporetic Socratic dialogues that find more systematic analysis and resolution in the more constructive dialogues that follow. After developing these concerns, analyses, and solutions, we sketch Aristotle's quite different treatment of the same and other related issues.


James Bogen and Charles Young presented "Contrariety and Change" to the Society for Ancient Greek Philosophy at its meeting with the Pacific Division of the American Philosophical Association in Los Angeles in April 1994. A much later and revised version was published in the International Journal of Scientific Research and Innovative Technology 1.4 (2014) 45-62.
