The Indefinite Dyad and the Golden Section: Uncovering Plato's Second Principle

Abstract

Scott Olsen examines the philosophy of Plato to bring to light the nature of Plato's Second Principle, known as the Indefinite Dyad, sometimes called the Greater and the Lesser, and its relation to the Golden Section. He responds to the challenge posed in 1983 by Kenneth Sayre, and explains how the the Indefinite Dyad can be used to derive the square roots of 2 and 3.[PUBLICATION ABSTRACT]
