Love is between two particular people in their particularity. We cannot love just anyone, even others with much the same qualities. If we did, then when we met someone like the beloved but who possessed a little more of a quality to which we were drawn, we would, in the phrase philosophers of love use, “trade up.” But we don’t trade up, or at least most of us don’t. This is because we love that particular person in his or her specificity. And what we create together, our common projects and shared emotions, are grounded in those specificities. Romantic love is not capable of everything. It is capable only of what the unfolding of a future between two specific people can meaningfully allow.
