Empedocles says, that the similitude of children to their parents proceeds from the vigorous prevalency of the generating sperm; the dissimilitude from the evaporation of the natural heat it contains. Parmenides, that when the sperm falls on the right side of the womb, then the infant gives the resemblance of the father; if from the left, it is stamped with the similitude of the mother. The Stoics, that the whole body and soul give the sperm; and hence arise the likenesses in the characters and faces of the children, as a painter in his copy imitates the colors in a picture before him. Women have a concurrent emission of seed; if the feminine seed have the predominancy, the child resembles the mother; if the masculine, the father.
