Extracts from Gilles Deleuze, “Immanence: A Life” in Pure Immanence: Essays on Life (extracts p. 28-32, ital. added):
Between his life and his death, there is a moment that is only that of a life playing with death. The life of the individual gives way to an impersonal and yet singular life that releases a pure event freed from the accidents of internal and external life, that is, from the subjectivity and objectivity of what happens: a “Homo tantum” with // whom everyone empathizes and who attains a sort of beatitude. It is a haecceity no longer of individuation but of singularization: a life of pure immanence, neutral, beyond good and evil, for it was only the subject that incarnated it in the midst of things that made it good or bad. The life of such individuality fades away in favor of the singular life immanent to a man who no longer has a name, though he can be mistaken for no other. A singular essence, a life …
But we shouldn’t enclose life in the single moment when individual life confronts universal death. A life is everywhere, in all the moments that a given living subject goes through and that are measured by // are neither grouped nor divided in the same way. They connect with one another in a manner entirely different from how individuals connect. It even seems that a singular life might do without any individuality, without any other concomitant that individualizes it.
A life contains only virtuals. It is made up of virtualities, events, singularities. What we call virtual is not something that lacks reality but something that is engaged in a process of actualization following the plane that gives it its particular reality. The immanent event is actualized in a state of things and of the lived that make it happen. The plane of immanence is itself actualized in an object and a subject to which it attributes itself. But however inseparable an object and a subject may be from their actualization, the plane of immanence is itself virtual, so long as the events that populate it are virtualities. Events or singularities give to the plane all their virtuality, just as the plane of immanence gives virtual events their full reality. The event considered as non-actualized (indefinite) is lacking in nothing. It suffices to put it in relation to its concomitants: a transcendental field, a plane of immanence, a life, singularities. A wound is incarnated or actualized in a state of things or of life; but it is itself a pure virtuality on the plane of immanence that leads us into a life. My wound existed before me: not // a transcendence of the wound as higher actuality, but its immanence as a virtuality always within a milieu (plane or field). There is a big difference between the virtuals that define the immanence of the transcendental field and the possible forms that actualize them and transform them into something transcendent.
