The glands regulating personality

One-Page Summary

The Glands Regulating Personality is an early twentieth-century attempt to connect biology, hormones, temperament, and human behavior. Louis Berman argues that the endocrine glands—organs that release hormones into the body—have an important influence on physical characteristics and personality. The book belongs to a period when scientists and physicians were beginning to understand the endocrine system but had not yet reached the modern knowledge of hormone signaling and complex brain-behavior relationships. Berman goes further than contemporary evidence would justify by proposing broad “types” of human nature based on glandular patterns.

That makes the book historically fascinating but scientifically dated. It shows how strongly early twentieth-century medicine wanted to explain personality in biological terms and how tempting it was to turn complicated human differences into neat classifications. Modern readers should therefore treat the book as a history-of-science document rather than a reliable guide to personality. Its deeper interest is the enduring desire to answer a difficult question: how much of who we are comes from the body, and how much is shaped by experience, culture, and choice?
