 One objection to the contractual account is that, without appeal to the purpose of the institution, there is no reason why not just any set of promises count as marriage (Finnis 2008). The objection continues that the contractual account cannot explain the point of marriage. Some marriage contractualists accept this implication. According to the “bachelor’s argument,” marriage is irrational: chances of a strongly dis-preferred outcome (a loveless marriage) are too high (Moller 2003). Defenders of the rationality of marriage have replied that marital obligations are rational because they help agents to secure their long-term interests in the face of passing desires (Landau 2004). From the institutional perspective, evaluating the rationality of marriage thus, in terms of fulfilling subjective preferences, clashes with the tradition of viewing it as uniquely enabling certain objective human goods; however, a positive case must be made for the latter view.
