"The most evident of the wonders described in the book On the Use of the Limbs ... is clearly perceived by all who examine them with a sharp eye. In a similar manner did God provide for each individual animal of the class of mammalia. When such an animal is born it is extremely tender, and cannot be fed with dry food. Therefore breasts were provided which yield milk, and the young can be fed with moist food which corresponds to the condition of the limbs of the animal, until the latter have gradually become dry and hard. Many precepts in our Law are the result of a similar course adopted by the same Supreme Being. It is, namely, impossible to go suddenly from one extreme to the other; it is therefore according to the nature of man impossible for him suddenly to discontinue everything to which he has been accustomed."

“We suffer from the evils which we, by our own free will, inflict on ourselves and ascribe them to God, who is far from being connected with them!”

“All the great evils which men cause to each other because of certain intentions, desires, opinions, or religious principles, are likewise due to non-existence, because they originate in ignorance, which is absence of wisdom.”

“Those who are ignorant and perverse in their thought are constantly in trouble and pain, because they cannot get as much of the superfluous things as a certain other person possesses. They as a rule expose themselves to great dangers... for the purpose of obtaining that which is superfluous and not necessary. When they thus meet with the consequences of the course which they adopt, they complain of the decrees and the judgements of God; they begin to blame the time, and wonder at the want of justice in its changes; that it has not enabled them to acquire great riches... for the purpose of driving themselves to voluptuousness beyond their capacities, as if the whole Universe existed only for the purpose of giving pleasure to these low people.”

“Those who desire to be men in truth, and not brutes, having only the appearance and shape of men, must constantly endeavor to reduce the wants of the body, such as eating, love, drinking, anger, and all manners originating in lust and passion; they must feel ashamed of them and set limits to them for themselves.”

“He fully knows His unchangeable essence, and has thus a knowledge of all that results from any of His acts. If we were to try to understand in what manner this is done, it would be the same as if we tried to be the same as God, and to make our knowledge identical with His knowledge. Those who seek the truth, and admit what is true, must believe that nothing is hidden from God; that everything is revealed to His knowledge, which is identical with His essence; that this kind of knowledge cannot be comprehended by us; for if we knew its method, we would possess that intellect by which such knowledge could be acquired. ...Note this well, for I think that this is an excellent idea, and leads to correct views; no error will be found in it; no dialectical argument; it does not lead to any absurd conclusion, nor to ascribing any defect to God. These sublime and profound themes admit of no proof whatever... In all questions that cannot be demonstrated, we must adopt the method which we have adopted in this question about God's Omniscience. Note it.”
