But medicine has long had all its means to hand, and has discovered both a principle and a method, through which the discoveries made during a long period are many and excellent, while full discovery will be made, if the inquirer be competent, conduct his researches with knowledge of the discoveries already made, and make them his starting-point. But anyone who, casting aside and rejecting all these means, attempts to conduct research in any other way or after another fashion, and asserts that he has found out anything, is and has been victim of deception.

Cure sometimes, treat often, comfort always.

Health is the greatest of human blessings.

Just as food causes chronic disease, it can be the most powerful cure

From nothing else but the brain come joys, delights, laughter and sports, and sorrows, griefs, despondency, and lamentations

...all the most acute, most powerful, and most deadly diseases, and those which are most difficult to be understood by the inexperienced, fall upon the brain.

The physician must have at his command a certain ready wit, as dourness is repulsive both to the healthy and the sick.
