Man a Machine

The most dangerous idea of the 18th century: you are not a soul trapped in flesh, you are nothing but flesh. Julien Offray de La Mettrie, a physician and philosopher, had the audacity to publish this argument in 1747, and within a year he was forced to flee France for Prussia. Man a Machine takes Descartes' provocative claim that animals are mere automatons and extends it to human beings. There is no separate soul, no immortal essence, only the machinery of the body, governed by physical laws, shaped by anatomy and physiology. Drawing on his medical practice, La Mettrie shows how brain injuries alter personality, how bodily disturbances affect the mind, how thought itself might be nothing but the motion of organic parts. The Church condemned it. Frederick the Great embraced it. The text remains a bracing provocation to anyone who has ever wondered whether there is something more to being human, or whether the answer might be far stranger and more material than we wish to believe.
