Becoming Father the Nurturer rather than just Father the Provider enables a man to fully feel and express his humanity and his masculinity. Fathering is the most masculine thing a man can do.

In time, after a dozen years of centering their lives around the games boys play with one another, the boys' bodies change and that changes everything else. But the memories are not erased of that safest time in the lives of men, when their prime concern was playing games with guys who just wanted to be their friendly competitors. Life never again gets so simple.

At the heart of male bonding is this experience of boys in early puberty: they know they must break free from their mothers and the civilized world of women, but they are not ready yet for the world of men, so they are only at home with other boys, equally outcast, equally frightened, and equally involved in posturing what they believe to be manhood.

I'm not suggesting that all men are beautiful, vulnerable boys, but we all started out that way. What happened to us? How did we become monsters of feminist nightmares? The answer, of course, is that we underwent a careful and deliberate process of gender training, sometimes brutal, always dehumanizing, cutting away large chunks of ourselves. Little girls went through something similarly crippling. If the gender training was successful, we each ended up being half a person.

The child who would be an adult must give up any lingering childlike sense of parental power, either the magical ability to solveyour problems for you or the dreaded ability to make you turn back into a child. When you are no longer hiding from your parents, or clinging to them, and can accept them as fellow human beings, then they may do the same for you.

Common courtesy plays a big role in happy marriages. People who are permanently married are polite to one another. They don't want to hurt one another's feelings, and they don't try to make the other one feel humiliated. People who are married for life are extremely kind to one another.

The problem is simply this: no one can feel like CEO of his or her life in the presence of the people who toilet trained her and spanked him when he was naughty. We may have become Masters of the Universe, accustomed to giving life and taking it away, casually ordering people into battle or out of their jobs . . . and yet we may still dirty our diapers at the sound of our mommy's whimper or our daddy's growl.
