For that which is without a beginning, a final cause need not be sought. - Moshe ben Maimon

Whatever God desires to do is necessarily done; there is nothing that could prevent the realisation of His will. The object of His will is only that which is possible, and of the things possible only such as His wisdom decrees upon. When God desires to produce the best work, no obstacle or hindrance intervenes between Him and that work. This is the opinion held by all religious people, also by the philosophers; it is also our opinion. For although we believe that God created the Universe from nothing, most of our wise and learned men believe that the Creation was not the exclusive result of His will; but His wisdom, which we are unable to comprehend, made the actual existence of the Universe necessary. The same unchangeable wisdom found it as necessary that non-existence should precede the existence of the Universe. Our Sages frequently express this idea in the explanation of the words, "He hath made everything beautiful in his time" (Eccl. iii. 11)... This is the belief of most of our Theologians; and in a similar manner have the Prophets expressed the idea that all parts of natural products are well arranged, in good order, connected with each other, and stand to each other in the relation of cause and effect; nothing of them is purposeless, trivial, or vain; they are all the result of great wisdom. ...This idea occurs frequently; there is no necessity to believe otherwise; philosophic speculation leads to the same result; viz., that in the whole of Nature there is nothing purposeless, trivial, or unnecessary, especially in the nature of the spheres, which are in the best condition and order, in accordance with their superior substance.

Abraham was the first to teach the Unity of God, to establish the faith, to cause it to remain among coming generations, and to win his fellow-men to his doctrine; as Scripture says of him: "I know him, that he will command," &c. (Gen. xviii. 19)

By following entirely the guidance of lust, in the manner of fools, man loses his intellectual energy, injures his body, and perishes before his natural time; sighs and cares multiply; there is an increase of envy, hatred, and warfare, for the purpose of taking what another possesses. The cause of all this is the circumstance that the ignorant considers physical enjoyment as an object to be sought for its own sake. God in His wisdom has therefore given us such commandments as would counteract that object, and prevent us altogether from directing our attention to it, and has debarred us from everything that leads only to excessive desire and to lust. This is an important thing included in the objects of our Law.
