Man's shortcomings and sins are all due to the substance of the body and not to its form; while all his merits are exclusively due to his form. - Moshe ben Maimon

The proposition has... been laid down in the most general terms, "All evils are negations." Thus for man death is evil; death is his non-existence. Illness, poverty, and ignorance are evils for man; all these are privations of properties. ...The destruction of other things is likewise nothing but the absence of their form. After these propositions, it must be admitted as a fact that it cannot be said of God that He directly creates evil, or He has the direct intention to produce evil; this is impossible. His works are all perfectly good. He only produces existence, and all existence is good; whilst evils are of a negative character, and cannot be acted upon.

The Torah sage ... does not encroach upon another's occupation, nor does he ever cause someone discomfort. The rule is that he should be among the pursued and not the pursuers, among those who accept humiliation but not among those who humiliate others.

Teach thy tongue to say I do not know, and thou shalt progress.
