Now we know the answer: the brain. But ancient humanity did not know. A number of famous thinkers have placed the mind in a number of places around the body
- Aristotle: the heart. It is the center of the body and the first organ to be discerned in an embryo
- Thomas Aquinas: the ventricles (empty spaces) of the brain. Being pure spirit, the mind lives in the empty parts of the body and survives beyond death.
- Rene Descartes: the pineal gland.
