Among all the modes by which love is brought into being, among all the agents which disseminate that blessed bane, there are few so efficacious as this gust of feverish agitation that sweeps over us from time to time. For then the die is cast, the person whose company we enjoy at that moment is the person we shall henceforward love. It is not even necessary for that person to have attracted us, up till then, more than or even as much as others. All that was needed was that our predilection should become exclusive. And that condition is fulfilled when — in this moment of deprivation — the quest for the pleasures we enjoyed in his or her company is suddenly replaced by an anxious, torturing need, whose object is the person alone, an absurd, irrational need which the laws of this world make it impossible to satisfy and difficult to assuage — the insensate, agonising need to possess exclusively.
Marcel Proust, Swann's Way
