More broadly across time and cultures, it seems, one perennial piece of advice to father has been the importance of acting tenderly toward their children. The New Father, it turns out, is an old story.

The most urgent domestic challenge facing the United States at the close of the 20th century is the re-creation of fatherhood as a social role for men.

Children have a primal need to know who they are, to love and be loved by the two people whose physical union brought them here. To lose that connection, that sense of identity, is to experience a wound that no child-support check or fancy school can ever heal.

When a man does not live with his children and does not get along with the mother of his children, his fatherhood becomes essentially untenable, regardless of how he feels, how hard he tries, or whether he is a good guy. Almost by definition, he has become de-fathered.

To recover the fatherhood idea, we must fashion a new cultural story of fatherhood. The moral of today's story is that fatherhoodis superfluous. The moral of the new story must be that fatherhood is essential.

We would be more American on the day we permitted same-sex marriage than we were on the day before.

The U.S. is becoming an increasingly fatherless society. A generation ago, an American child could reasonably expect to grow up with his or her father. Today an American child can reasonably expect not to. Fatherlessness is now approaching a rough parity with fatherhood as a defining feature of American childhood.

Even with all its problems, I will support marriage as an institution until something better comes along.
