Pragma is a kind of practical love founded on reason or duty and one’s longer-term interests. Sexual attraction takes a back seat in favor of personal qualities and compatibilities, shared goals, and making it work. In the days of arranged marriages, pragma must have been very common. Although unfashionable, it remains widespread, most visibly in certain high-profile celebrity and political pairings. Many relationships that start off as eros or ludus end up as various combinations of storge and pragma. Pragma may seem opposed to ludus, but the two can co-exist, with the one providing a counterpoint to the other. In the best of cases, the partners in the pragma relationship agree to turn a blind eye or even, as in the case of Simone de Beauvoir and Jean-Paul Sartre, a sympathetic eye.
