When one desire fills the whole frame, the alternatives stop counting as options and the choice is already finished.
Desire narrows the field before reason gets its turn. A young man whose eyes are full of one person is not weighing anybody, because every other option has been deleted from the list he is choosing from, and a list of one feels like certainty while operating as tunnel vision. Parents reciting alternatives cannot restore what attention has already removed; only a redirected look does that.
Pleasure was the whole criterion, and pleasure this close always outweighs a consequence years out, since only one of the two is in view. A man who never puts the later price in front of his eyes spends his strength on a life his eyes picked for him before he ever deliberated.
