Book

Man, The Unknown

by Alexis Carrel

Summary

Alexis Carrel’s "Man, The Unknown" argues that modern civilization has neglected the holistic study of human beings, reducing them to mere biological or mechanical components. Carrel, a Nobel Prize-winning biologist, contends that science must integrate physiology, psychology, and spirituality to understand humanity fully, warning that technological progress without self-knowledge leads to societal decay. He critiques specialization in medicine and education, advocating for a return to intuitive, experiential knowledge of the body and mind. The book synthesizes early 20th-century research on organ function, consciousness, and heredity, proposing that humans possess latent psychic and physiological powers that modern life suppresses. Readers take away a call to rebalance scientific reductionism with a broader, more humanistic view of existence.

  • Organic timeThe concept that biological processes follow rhythms distinct from mechanical clock time, influencing aging, healing, and consciousness.
