Abstract

There was once a time when philosophers marvelled that man could move his limbs even though he was not familiar with the nerve and muscle processes on which such movements depended. They even went so far as to conclude that man was quite incapable of moving his body by himself. Whenever he wished to perform some movement, they believed, a higher power had to come to his aid and do it for him.
