Abstract: Why do many human societies condemn apparently harmless and pleasurable behaviors, such as lust, gluttony, drinking, drugs, gambling, or even music and dance? Why do they erect temperance, hedonic restraint, sobriety, decency and piety as cardinal moral virtues? While existing accounts consider this puritanical morality as an exception to the cooperative function of moral intuitions, we propose that it stems, like other moral concerns, from moral intuitions targeting cooperative challenges. Specifically, we argue that it emerges in response to a key feature of cooperation, namely that the latter is (ultimately) a long-term strategy, requiring (proximately) the self-control of appetites for immediate gratification. Puritanical moralizations condemn and praise behaviors which, although not intrinsically cooperative or uncooperative, are perceived as affecting people’s propensity to cooperate, by modifying their ability to resist short-term impulses conflicting with cooperative motivations. Drinking, drugs, unruly feasts, dances, and immodest clothing are condemned as stimulating people’s short-term impulses, thus facilitating uncooperative behaviors (e.g. adultery, violence, economic free-riding). Immoderate indulgence in harmless bodily pleasures (e.g. lust, masturbation, gluttony) is perceived as addictively reinforcing short-term impulses, thus making harder the self-control of future temptations to cheat. Moralizations of ascetic temperance, daily self-discipline, and pious ritual observance are perceived as nurturing the self-restraint consubstantial to a cooperative character, able to resist selfish temptations when the latter arise. We review psychological, historical, and ethnographic evidence supporting this account, and discuss its implications regarding the cross-cultural variations and cultural evolution of puritanical norms.
