Throughout the animal kingdom—from mammals and birds down to insects—there are complicated mating rituals, behaviors we refer to archly as “courtship” rituals.
Still, certain things have to happen at different times. There are societies in which conventional dating, as we know it, does not exist. Nothing like courtship existed in these relationships.
There is still the widespread practice of arranged marriages.
They tend to work in cultures which support pairing off in this way.
Even then, the participants sometimes have the right to say no.
These cultures demonstrate that love is not a necessary condition of a marriage.
Western ways prove, I think, that it is not sufficient.
