Abstract

Monogamy in Western countries has recently undergone criticisms, because it is perceived as an oppressive institution, adjacent to reactionary cultural values. In this article, I argue that monogamy is in fact a force of social progress and women’s empowerment. I point out that, given our natural tendencies, the most likely alternative to monogamy is polygyny. By its very nature, polygyny faces a numerical difficulty, to the extent that (given the equitable male to female ratio) when one man engages in romantic or sexual relationships with multiple female partners, inequality and social conflict ensues. I present historical and sociological data that sustains the argument that polygyny is associated with greater inequality, violence, poverty and women’s vulnerability. Nevertheless, while monogamy can be considered a force of social progress, I argue that the State is not morally entitled to prosecute non-monogamous lifestyles, but there may still be non-coercive ways to promote monogamy.
