The greatest mistake in the treatment of diseases is that there are physicians for the body and physicians for the soul, although the two cannot be separated.
There is a wisdom in this beyond the rules of physic: a man's own observation what he finds good of and what he finds hurt of is the best physic to preserve health.
The sign of vigour, the sign of life, the sign of hope, the sign of health, the sign of everything that is good, is strength. As long as the body lives, there must be strength in the body, strength in the mind, [and strength] in the hand.
