Justice_ What's the Right Thing to Do_ - Michael Sandel [124]
If marriage is an honorific institution, what virtues does it honor? To ask that question is to ask about the purpose, or telos, of marriage as a social institution. Many opponents of same-sex marriage claim that the primary purpose of marriage is procreation. According to this argument, since same-sex couples are unable to procreate on their own, they don’t have a right to marry. They lack, so to speak, the relevant virtue.
This teleological line of reasoning is at the heart of the case against same-sex marriage, and Marshall takes it on directly. She does not pretend to be neutral on the purpose of marriage, but offers a rival interpretation of it. The essence of marriage, she maintains, is not procreation but an exclusive, loving commitment between two partners—be they straight or gay.
Now, how, you might ask, is it possible to adjudicate between rival accounts of the purpose, or essence, of marriage? Is it possible to argue rationally about the meaning and purpose of morally contested social institutions such as marriage? Or is it simply a clash of bald assertions—some say it’s about procreation, others say it’s about loving commitment—and there’s no way of showing one to be more plausible than the other?
Marshall’s opinion offers a good illustration of how such arguments can proceed. First, she disputes the claim that procreation is the primary purpose of marriage. She does so by showing that marriage, as currently practiced and regulated by the state, does not require the ability to procreate. Heterosexual couples who apply for marriage licenses are not asked about “their ability or intention to conceive children by coitus. Fertility is not a condition of marriage, nor is it grounds for divorce. People who have never consummated their marriage, and never plan to, may be and stay married. People who cannot stir from their deathbed may marry.” While “many, perhaps most married couples have children together (assisted or unassisted),” Marshall concludes, “it is the exclusive and permanent commitment of the marriage partners to one another, not the begetting of children, that is the sine qua non of civil marriage.”37
So part of Marshall’s argument consists of an interpretation of the purpose or essence of marriage as it currently exists. Faced with rival interpretations of a social practice—marriage-as-procreation versus marriage-as-exclusive-and-permanent-commitment—how can we determine which is more plausible? One way is to ask which account makes better sense of existing marriage laws, taken as a whole. Another is to ask which interpretation of marriage celebrates virtues worth honoring. What counts as the purpose of marriage partly depends on what qualities we think marriage should celebrate and affirm. This makes the underlying moral and religious controversy unavoidable: What is the moral status of gay and lesbian relationships?
Marshall is not neutral on this question. She argues that same-sex relationships are as worthy of respect as heterosexual relationships. Restricting marriage to heterosexuals “confers an official stamp of approval on the destructive stereotype that same-sex relationships are inherently unstable and inferior to opposite-sex relationships and are not worthy of respect.”38
So when we look closely at the case for same-sex
