“Why does he who says this, since he is so dull in understanding nature, think it also of no consequence in whose womb and from whose blood the child is formed and fashioned? For is there not now in the breasts the same blood--whitened, it is true, by agration and heat--which was before in the womb? And is not the wisdom of Nature to be seen in this, that as soon as the blood has done its work of forming the body down below, and the time of birth has come, it betakes itself to the upper parts of the body, and is ready to cherish the spark of life and light by furnishing to the new-born babe his known and accustomed food? And so it is not an idle belief, that, just as the strength and character of the seed have their influence in determining the likeness of the body and mind, so do the nature and properties of the milk do their part in effecting the same results. And this has been noticed, not in man alone, but in cattle as well. For if kids are brought up on the milk of ewes, or lambs on that of goats, it is agreed that the latter have stiffer wool, the former softer hair. In the case of timber and fruit trees, too, the qualities of the water and soil from which they draw their nourishment have more influence in stunting or augmenting their growth than those of the seed which is sewn, and often you may see a vigorous and healthy tree when transplanted into another place perish owing to the poverty of the soil. “Is it then a reasonable thing to corrupt the fine qualities of the new-born man, well endowed as to both body and mind so far as parentage is concerned, with the unsuitable nourishment of degenerate and foreign milk? Especially is this the case, if she whom you get to supply the milk is a slave or of servile estate, and--as is very often the case--of a foreign and barbarous race, if she is dishonest, ugly, unchaste, or _addicted to drink_. For generally any woman who happens to have milk is called in, without further enquiry as to her suitability in other respects. Shall we allow this babe of ours to be tainted by pernicious contagion, and to draw life into his body and mind from a body and mind debased? "This is the reason why we are so often surprised that the children of chaste mothers resemble their parents neither in body nor character. “... And besides these considerations, who can afford to ignore or belittle the fact that those who desert their offspring and send them away from themselves, and make them over to others to nurse, cut, or at least loosen and weaken that chain and connection of mind and affection by which Nature attaches children to their parents. For when the child, sent elsewhere, is away from sight, the vigour of maternal solicitude little by little dies away, and the call of motherly instinct grows silent, and forgetfulness of a child sent away to nurse is not much less complete than that of one lost by death.
