Those who believe that... detailed rules originate in a certain cause, are as far from the truth as those who assume that the whole law is useless. - Moshe ben Maimon

Scripture says:—If a man should rise, pretend to be a prophet, and show you his signs by which he desired to convince you that his words are true, know that God intends thereby to prove to the nations how firmly you believe in the truth of God's Word, and how well you have comprehended the true Essence of God; that you cannot be misled by any tempter to corrupt your faith in God. Your religion will then afford a guidance to all who seek the truth, and of all religions man will choose that which is so firmly established that it is not shaken by the performance of a miracle. For a miracle cannot prove that which is impossible; it is useful only as a confirmation of that which is possible, as we have explained in our Mishneh-torah.

It is of great advantage that man should know his station, and not imagine that the whole universe exists only for him. We hold that the universe exists because the Creator wills it so; that mankind is low in rank as compared with the uppermost portion of the universe, viz., with the spheres and the stars; but, as regards the angels, there cannot be any real comparison between man and angels, although man is the highest of all beings on earth; i.e., of all the beings formed of the four elements.

It was necessary that the very noble form of man, which is the image and likeness of God... should be joined to the substance of dust and darkness, the source of all defect and loss. For these reasons the Creator gave to the form of man power, rule, and dominion over the substance;—the form can subdue the substance, refuse the fulfillment of its desires, and reduce them, as far as possible, to a just and proper measure.
