“There is a kind of love—and for some it may be the only kind that qualifies as true love—that is historical precisely because it does not rigidly designate its object. . . . Such a love might be called dynamically permeable. It is permeable in that the lover is changed by loving and changed by truthful perception of the friend. . . . It is dynamic in that every change generates new changes, both in the lover and in interactions with the friend.”
