Abstract

A problem is posed: Is pleasure choiceworthy, or not? The answerer claims that yes, it is. The questioner must refute him by asking questions—by offering him premises to accept or reject. The questioner succeeds if he forces the answerer to accept a proposition contrary to the one he undertook to defend, and fails if the answerer always accepts or rejects premises in a way consistent with that proposition. To a first approximation, dialectic is the distinctive method of Aristotelian philosophy. At the heart of dialectic is the dialectical deduction. This article discusses Aristotle's philosophical method, focusing on dialectical premises, endoxa, and aporiai. It also examines the uses of dialectic in intellectual training, ordinary discussion, and the philosophical sciences, as well as in regard to scientific starting points or first principles. The article concludes by returning to dialectic and philosophy and an important difference between them.
