Context: The most evident of the wonders described in the book On the Use of the Limbs [by Galen]... 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.
