The Attraction of Opposites considers a puzzling phenomenon: Why do societies all over the world organize their social thought and institutions in patterns of opposites? The essays collected in this volume examine contemporary societies throughout the world that organize their social theories or institutions in binary form. Through analysis of these rich materials, the distinguished contributors explore the enduring human attraction to dualism. They consider whether this is due to the natural “twoness” of things and, if not, why polarity should play such a prominent role in both ancient cosmologies and modern philosophies, in early empires and in modern two-party systems. This study of dual organization tells us something important about human beings, illuminating a mode of thought and social organization that has represented an attractive option throughout human history.
