"You must accept the truth from whatever source it comes." — Maimonides

If the whole earth is infinitely small in comparison with the sphere of the stars, what is man compared with all these created beings!

If men possessed wisdom, which stands in the same relation to the form of man as the sight to the eye, they would not cause any injury to themselves or to others; for the knowledge of truth removes hatred and quarrels, and prevents mutual injuries.

Man's shortcomings and sins are all due to substance of the body and not to its form, while all his merits are exclusively due to his form.

Form can only be destroyed accidentally, i.e., on account of its connexion with substance, the true nature of which consists in the property of never being without a disposition to receive form.
