Passions and Tempers: A History of the Humours

“Passions and Tempers may excite passions and tempers in some of its readers, as a good work of intellectual history should. You will learn a lot from its pages.”

—Washington Post

The humours—blood, phlegm, black bile, and choler—were substances thought to circulate within the body and determine a person’s health, mood, and character. The theory of humours remained an inexact but powerful tool for centuries, surviving scientific changes and offering clarity to physicians.

This one-of-a-kind book follows the fate of these variable and invisible fluids from their Western origin in ancient Greece to their present-day versions. It traces their persistence from medical guidebooks of the past to current health fads, from the testimonies of medical doctors to the theories of scientists, physicians, and philosophers. By intertwining the histories of medicine, science, psychology, and philosophy, Noga Arikha revisits and revises how we think about all aspects of our physical, mental, and emotional selves.
