The Illustrated Self-Instructor in Phrenology and Physiology

"The Illustrated Self-Instructor in Phrenology and Physiology" by O. S. (Orson Squire) Fowler is a mid-1800s educational book explaining phrenology and physiology, and how the shape of the brain affects character. The book teaches readers about matching brain features to personality traits to learn about themselves and the people around them. The writers share a persuasive argument for understanding oneself as key to improving as a person and helping society. Tables and lists link physical traits to character, and introduce aspects of phrenology that match skull and brain shapes to human behaviors.
