Tom Cerber also calls our attention to and comments on this piece, in which Jonathan Rauch tries to decouple same-sex marriage from polygamy. Offering a good public policy argument against polygamy--imagine lots of men without the prospect of marriage and imagine how uncivilized theyd likely be--Rauch by implication raises, as Cerber notes, the connection between marriage and liberal democracy. Whats the connection--historical and theoretical--between traditional monogamy and liberal democracy? Cerber has the right answer. Rauch wants to avoid the question.
