Astrology is a disease, not a science... It is a tree under the shadow of which all sorts of superstitions thrive. ... Only fools and charlatans lend value to it.

Every man should view himself as equally balanced: half good and half evil. Likewise, he should see the entire world as half good and half evil.... With a single good deed he will tip the scales for himself, and for the entire world, to the side of good.

He, however, who begins with Metaphysics, will not only become confused in matters of religion, but will fall into complete infidelity.

No disease that can be treated by diet should be treated with any other means.

A wise man is a greater asset to a nation than a king.

The physician should not treat the disease but the patient who is suffering from it

The risk of a wrong decision is preferable to the terror of indecision.
