They are like adverts for desiring. How strange this is; the ways in which fantasy at once blackmails or seduces or lures us into going through with our wanting, and at the same time pre-empts our going through with it; that we have to do this to ourselves, as though we are at best resistant and at worst phobic of wanting, of acknowledging our wants. We have to be attentive, in other words, to what we use fantasy to do; whether it becomes, as we say, an end in itself.
