The key to the understanding and to the full comprehension of all that the Prophets have said is found in the knowledge of the figures, their general… - Moshe ben Maimon

The portion of the materia prima which is... is endowed with the intellectual faculty, possesses a special property by which each individual, according to the degree of his perfection, is enabled to manage, to calculate, and to discover what is conducive both to the temporary existence of the individual and to the preservation of the species. All other movements... by the individual members of the species are due to accident; they are not, according to Aristotle, the result of rule and management... Aristotle sees no difference between the falling of a leaf or a stone and the death of the good and noble people in the ship; nor does he distinguish between the destruction of a multitude of ants by an ox depositing on them his excrement and the death of worshippers killed by the fall of the house when its foundations give way.

There shall always be much silence in a man's conduct. He shall speak only about a matter concerned with wisdom or matters that are necessary to keep his body alive.

For that which is without a beginning, a final cause need not be sought.
