Psychology Books

Psychology as a formal discipline is barely 150 years old. Before that, the interior life of human beings was the province of philosophers, novelists, priests, and poets. What the late 19th century changed was the decision to treat the mind as something that could be studied methodically — and what emerged was a new kind of literature, half science and half introspection.

Freud's *Interpretation of Dreams* (1899) is the founding document, and it's as much a literary work as a scientific one. It reads like a detective novel about the unconscious. William James's *Principles of Psychology* turned a medical field into a humanist one. Jung's *Psychological Types* introduced the vocabulary (introvert, extravert) we still use for personality. And before any of them, the novelists — Dostoevsky, George Eliot, Henry James — were mapping the interior life with a precision the scientists would spend decades catching up to.

Reading the classic psychology texts now is a useful corrective to pop psychology. The original works are more cautious, more literary, and often more honest about what can and can't be known.
