They likewise were of opinion that great providential attention should be paid by those who beget children, to the future progeny. The first, therefore, and the greatest care which should be taken by him who applies himself to the procreation of children is, that he lives temperately and healthfully, that he neither fills himself with food unseasonably, nor uses such aliments as may render the habits of the body worse than they were, and above all things, that he avoids intoxication. For they thought that depraved seed was produced from a bad, discordant, and turbid temperament. And universally they were of opinion, that none but an indolent and inconsiderate person would attempt to produce an animal, and lead it into existence, without providing with all possible diligence that its ingress into being and life might be most elegant and pleasing. For those that are lovers of dogs, pay every possible attention to the generation of whelps, in order that they may be produced from such things as are proper, and when it is proper, and in such a way as is proper, and thus may become a good offspring. The same attention also is paid by those who are lovers of birds. And it is evident that others also who are studious about the procreation of generous animals, endeavour by all possible means, that the generation of them may not be in vain. It would be absurd therefore that men should pay no attention to their own offspring, but should both beget them casually and with perfect carelessness, and, after they are begotten, nourish and educate them with extreme negligence. For this is the most powerful and most manifest cause of the vice and depravity of the greater part of mankind. For with the multitude the procreation of children is undertaken in a beastly and rash manner. And such were the assertions, and such the doctrine of these men, which they verified both in words and deeds, respecting temperance; these precepts having been originally received by them from Pythagoras himself, like certain oracles delivered by the Pythian Apollo.
