“We could not have civilization without intoxication,” says Professor Edward Slingerland in his important new book: Drunk: How We Sipped, Danced, and Stumbled Our Way to Civilization. Indeed, “the use of intoxicants should puzzle us as much as religion does.” This episode examines how and why intoxicants – and particularly alcohol -- have played such a crucial role in the evolution of human societies. Humans are, Professor Slingerland points out, “the only animals that deliberately and methodically get high.” Understanding the evolutionary dynamics of intoxicant use is essential to thinking clearly about the role intoxicants can and should play in our lives today.
