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

A sensible man ought to think about that well being is the best of human blessings, and find out how by his personal thought to derive profit from his sicknesses.

Make a habit of two things: to help; or at least to do no harm.

The wise man should consider that health is the greatest of human blessings. Let food be your medicine.

Men ought to know that from nothing else but the brain come joys, delights, laughter and sports, and sorrows, griefs, despondency, and lamentations. And by this, in an especial manner, we acquire wisdom and knowledge, and see and hear and know what are foul and what are fair, what are bad and what are good, what are sweet and what are unsavory…. And by the same organ we become mad and delirious, and fears and terrors assail us….All these things we endure from the brain when it is not healthy….In these ways I am of the opinion that the brain exercises the greatest power in the man.

The physician treats, but nature heals.

All diseases begin in the gut.
