Undoing marriage in Iowa

Matthew J. Franck writes at The Public Discourse:

...it is essential that public policy on marriage turn from love, and from lovers' felt need for "affirmation," to consider what reasons can be given for this or that way of arranging the family that makes a claim on our attention. Are all "relationships" created equal? Are all of them equally conducive to human flourishing? Is every way of bringing children into the world, or of rearing them, equally deserving of "affirmation"? How many men and/or women does it take to make a marriage that will perform the functions we want marriage to perform? Are children best prepared for healthy, responsible adult lives with both a mother and a father? Natural or "step-" or adopted? With a mother and a father or with "parents"? How many of each?

The laws of marriage and family, of divorce and custody, are efforts to address such questions rationally, if necessarily imperfectly, with the moral health of each party concerned being something to be optimized to the greatest extent possible. In the nature of things, someone's preferred notion of a "relationship" that needs "affirming" is always going to be left outside the moral pale, or so one would have thought until now. But on the Iowa court, all such questions, answered slowly and haltingly by G.K. Chesterton's democracy of the dead, the living, and the yet-unborn—otherwise known as "tradition"—are swept aside by the judges' solicitude for the "excluded" whose self-esteem is wounded. When desire becomes the foundation for a right, beware. Nothing in what passes for reasoning in Justice Cady's opinion can stand against the next claimant—perhaps the polygamist—who presents himself as needing affirmation for his relationships. This is not a slippery slope we have before us. It is the sight of a levee breaking in a spring flood.
