From The Superstition of Divorce (1920):
The child is an explanation of the father and mother and the fact that it is a human child is the explanation of the ancient human ties connecting the father and mother. The more human, that is the less bestial, is the child, the more lawful and lasting are the ties.

This triangle of truisms, of father, mother and child, cannot be destroyed; it can only destroy those civilisations which disregard it. Most modern reformers are merely bottomless sceptics, and have no basis on which to rebuild; and it is well that such reformers should realise that there is something they cannot reform. You can put down the mighty from their seat; you can turn the world upside down, and there is much to be said for the view that it may then be the right way up. But you cannot create a world in which the baby carries the mother. You cannot create a world in which the mother has no authority over the baby. ...
