A quote from Raymond Tallis, Aping Mankind: Neuromania, Darwinitis and the Misrepresentation of Humanity
p. 30 “The brain theory was contested by champions of other organs. The most famous was Aristotle, for whom the heart, not the brain, was the seat of the intellect. The brain, he said, served only to cool the blood; and perhaps in a sense it does.”
I have searched in Internet to check the information. I have found a paper that confirms the quote above.
Gross, C.G. Aristotle on the brain. The Neuroscientist, 1995, 1: 245-250
Abstract. Aristotle argued that the heart was the center of sensation and movement. By contrast, his predecessors, such as Alcmaeon, and his contemporaries, such as the Hippocratic doctors, attributed these functions to the brain. This article examines Aristotle’s views on brain function in the context of his time and considers their subsequent influence on the development of the brain sciences.
