or estimated, and that they constitute only a small part of each individual. The doctrine of heredity may seem to take out of our hands the conduct of our own lives, but it is the idea, not the fact, which is really terrible to us. For what we have received from our ancestors is only a fraction of what we are or may become. The knowledge that drunkenness or insanity has been prevalent in a family may be the best safeguard against their recurrence in a future generation. The parent will be most awake to the vices or diseases in his child of which he is most sensible within himself. The whole of life may be directed to their prevention or cure. The traces of consumption may become fainter, or be wholly effaced: the inherent tendency to vice or crime may be eradicated. And so heredity, from being a curse, may become a blessing. We acknowledge that in the matter of our birth, as in our nature generally, there are previous circumstances which affect us. But upon this platform of circumstances or within this wall of necessity, we have still the power of creating a life for ourselves by the informing energy of the human will.
There is another aspect of the marriage question to which Plato is a stranger. All the children born in his State are foundlings. It never occurred to him that the greater part of them, according to universal experience, would have perished. For children can only be brought up in families. There is a subtle sympathy between the mother and the child which cannot be supplied by other mothers, or by “strong nurses one or more” (“Laws” vii. 789 E). If Plato’s “pen” was as fatal as the crèches of Paris, or the foundling hospital of Dublin, more than nine-tenths of his children would have perished. There would have been no need to expose or put out of the way the weaklier children, for they would have died of themselves. So emphatically does nature protest against the destruction of the family.
What Plato had heard or seen of Sparta was applied by him in a mistaken way to his ideal commonwealth. He probably observed that both the Spartan men and women were superior in form and strength to the other Greeks; and this superiority he was disposed to attribute to the laws and customs relating to marriage. He did not consider that the desire of a noble offspring was a passion among the Spartans, or that their
