The first kind of evil is that which is caused to man by the circumstance that he is subject to genesis and destruction, or that he possesses a body. - Moshe ben Maimon

Maimonides was a zealous disciple of Aristotle, although the theory of the Kalām might seem to have been more congenial to Jewish thought and belief. The Kalām upheld the theory of God’s Existence, Incorporeality, and Unity, together with the creatio ex nihilo. Maimonides nevertheless opposed the Kalām, and, anticipating the question, why preference should be given to the system of Aristotle, which included the theory of the Eternity of the Universe, a theory contrary to the fundamental teaching of the Scriptures, he exposed the weakness of the Kalām and its fallacies.

Every human being should regard himself as if he were exactly balanced between innocence and guilt. Simultaneously he should regard the world as being in the same case. It follows then that if he performs one good deed, he has weighted the scales in favour of both himself and of the whole world, and thus brought about salvation both for himself and for all the inhabitants of the world.

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