Biography

American psychologist and philosopher who founded pragmatism and pioneered the psychology of religious experience. His personal struggle with depression and meaninglessness (resolved through a 'will to believe') informed his philosophy that truth is what works — ideas are validated by their fruits in lived experience. His Varieties of Religious Experience remains the classic study of mystical and transformative experiences across traditions.

Key contribution

Demonstrated that the test of any philosophy of meaning is its practical effect on living — and that religious/mystical experiences, regardless of their metaphysical status, are psychologically real and transformative.
