De qué trata este libro
Man a Machine is a short philosophical treatise by Julien Offray de La Mettrie, a French physician. It appeared in Leiden in 1747, and its title page carried the date 1748. La Mettrie had already been driven out of France for an earlier book on the soul. He now argued something bolder: that a human being is a self-moving machine, and that what we call the soul is a name for what the brain and nerves do.
The book gives you a compact, lively case for materialism written by a doctor who trusted his patients' bodies more than the theories of his teachers. It moves from illness and diet to apes and clockwork figures, and it ends by asking what is left for religion and morals. Let us begin with the first and simplest point: your mind rises and falls with your body.

The mind follows the state of the body
La Mettrie begins with plain observation. When the body changes, the mind changes with it. A fever makes a calm person raving. Hunger makes thought dull and bitter. A good meal lifts the spirits, and a cup of wine or a dose of opium can alter a person's whole view of life. He asks the reader to look at what happens, not at what theory says should happen.
He draws on his own experience as a doctor. He tells of his illness, a violent fever, during which he noticed that his thinking grew confused as his pulse raced. From this he concluded that the soul cannot be a separate ruler sitting calmly above the body. If it were, why would it fall ill when the body falls ill? Why would it weaken with age and sleep when the limbs tire?
He adds more cases. Climate and food shape character, he says, and so do the passions of the blood. Some people are bold because of their constitution, and some are timid. Even the fear of death, in his view, depends partly on bodily condition. The body is not a mere servant of the mind. It is the ground on which the mind stands.
For a reader today this sounds familiar, because we know that medicines, sleep and illness change mood and thought. In 1747 it was a provocation, since church teaching held that the soul was a distinct spiritual substance. La Mettrie does not shout. He simply keeps pointing to facts that any nurse or physician could confirm, and he leaves the reader to feel the weight of them.

Questions about El hombre máquina
What is Man a Machine about?

He means an organized body whose parts act on one another and move themselves, powered by food and blood. It is not a dead mechanism but a self-winding system, and thought is one of its functions.
Why was Man a Machine banned and condemned?
Authorities and clergy saw it as an attack on the immortal soul and on religion, and as hinting at atheism. It was condemned in the Netherlands, and La Mettrie had to seek shelter at Frederick the Great's court.
