A physician without a knowledge of Astrology has no right to call himself a physician.

Eunuchs do not take the gout, nor become bald.

The art has three factors, the disease, the patient, the physician. The physician is the servant of the art. The patient must cooperate with the physician in combatting the disease.

It's far more important to know what person the disease has than what disease the person has.

Life is short, and the Art long; the occasion fleeting; experience fallacious, and judgment difficult. The physician must not only be prepared to do what is right himself, but also to make the patient, the attendants, and externals cooperate.

All parts of the body which have a function, if used in moderation and exercised in labors in which each is accustomed, become thereby healthy, well developed and age more slowly, but if unused they become liable to disease, defective in growth and age quickly.

I am about to discuss the disease called 'sacred'. It is not, in my opinion, any more divine or more sacred that other diseases, but has a natural cause, and its supposed divine origin is due to men's inexperience, and to their wonder at its peculiar character.
