Utopia is not a good concept because even when opposed to History it is still subject to it and lodged within it as an ideal or motivation. But becoming is the concept itself. It is born in History, and falls back into it, but is not of it. In itself it has neither beginning nor end but only a milieu. It is thus more geographical than historical. Such are revolutions and societies of friends, societies of resistance, because to create is to resist: pure becomings, pure events on a plane of immanence. What History grasps of the event is its effectuation in states of affairs or in lived experience, but the event in its becoming, in its specific consistency, in its self-positing as concept, escapes History. Psychosocial types are historical, but conceptual personae are events. Sometimes one ages in accordance with History, and with it, sometimes one becomes old in a quite unobtrusive event (perhaps the same event that allows the problem “what is philosophy?” to be posed). And it is the same for those who die young there are several ways of so dying. To think is to experiment, but experimentation is always that which is in the process of coming about-the new, remarkable, and interesting that replace the appearance of truth and are more demanding than it is. What is in the process of coming about is no more what ends than what begins.
