 It is sometimes argued that traditions, having stood the test of time, have proved their value. Not only is marriage itself such a tradition, but through its child-rearing role it can pass on other traditions (Sommers 1989, Scruton 1986, 356–361, cf. Devlin 1965, Chapter 4). But many marital traditions—coverture, gender-structured legal duties, marital rape exemptions, inter-racial marriage bans—have been unjust. Tradition provides at best a prima facie reason for legislation which may be overridden by considerations of justice. Further, in a diverse society, there are many competing traditions, amongst which this rationale fails to choose (Garrett 2008).
