It is the father's business, again, to maintain some sort of equilibrium between the two modes of love in his infant. A mother may wish to bring up her child from the lovely upper centers only, from the centers of the breast, in the mode of what we call pure or spiritual love. Then the child will be all gentle, all tender and tender-radiant, always enfolded with gentleness and forbearance, always shielded from grossness or pain or roughness. Now the father's instinct is to be rough and crude, good-naturedly brutal with the child, calling the deeper centers, the sensual centers, into play. "What do you want? My watch? Well, you can't have it, do you see, because it's mine." Not a lot of explanations of the "You see, darling." No such nonsense.--Or if a child wails unnecessarily for its mother, the father must be the check. "Stop your noise, you little brat! What ails you, you whiner?" And if children be too sensitive, too sympathetic, then it will do the child no harm if the father occasionally throws the cat out of the window, or kicks the dog, or raises a storm in the house. Storms there must be. And if the child is old enough and robust enough, it can occasionally have its bottom soundly spanked--by the father, if the mother refuses to perform that most necessary duty. For a child's bottom is made occasionally to be spanked. The vibration of the spanking acts direct upon the spinal nerve-system, there is a direct reciprocity and reaction, the spanker transfers his wrath to the great will-centers in the child, and these will-centers react intensely, are vivified and educated. On the other hand, given a mother who is too generally hard or indifferent, then it rests with the father to provide the delicate sympathy and the refined discipline. Then the father must show the tender sensitiveness of the upper mode. The sad thing to-day is that so few mothers have any deep bowels of love--or even the breast of love. What they have is the benevolent spiritual will, the will of the upper self. But the will is not love. And benevolence in a parent is a poison. It is bullying. In these circumstances the father must give delicate adjustment, and, above all, some warm, native love from the richer sensual self.
