What was Descartes the first to do? What does Descartes say about the mind and the body -
ANSWER Discoveries
•The mind and the body are materially separate and obey different laws. Mind = spiritual =
soul. The body cannot exist without the mind. The mind, however, can exist without the
body. The mind can have consciousness when body is in coma. He was the first to look at
brain anatomy this way: that one structure does one thing
1
,•The mind and the body come together in the pineal gland (top of spinal cord where the
spinal cord joins the mind). The pineal gland tilted within the mind to allow the animal
spirits to flow down and control the body (like lifting up an arm). The pineal gland is the
structure that does so because it is in the midline between the two hemisphere and there is
only one unlike all other structures in the brain.
Societal reaction
Public thought this was weird and later was formally argued against it saying there was no
ghost in the machine. All mind is the result of biological activity occurring at the cellular level
(which is called scientific materialism)
