Brain
According to Aristotle, it is a cooling organ of the body. Early in the history of philosophy, it was regarded as closely connected with consciousness and with activities of the soul. Descartes contended that mind-body relations are centered in the pineal gland located between the two hemispheres of the brain. Cabanis, a sensualistic materialist, believed that the brain produces consciousness in a manner similar to that in which the liver produces the bile. Many have sought to identify it with the seat of the soul. Today consciousness is recognized to be a much more complex phenomenon controlled by the entire nervous system, rather than by any part of the brain, and influenced by the bodily metabolism in general. — R.B.W.
