Spirit is itself the wound it tries to heal, that is, the wound is self-inflicted. “Spirit” at its most elementary is the “wound” of nature. The subject is the immense— absolute— power of negativity, the power of introducing a gap or cut into the given – immediate substantial unity, the power of differentiating , of “abstracting,” of tearing apart and treating as self-standing what in reality is part of an organic unity. This is why the notion of the “self-alienation” of Spirit is more paradoxical than it may appear: it should be read together with Hegel’s assertion of the thoroughly non-substantial character of Spirit: there is no res cogitans, no thing which also thinks, Spirit is nothing but the process of overcoming natural immediacy, of the cultivation of this immediacy, of withdrawing -into-itself or “taking off” from it, of— why not?— alienating itself from it. The paradox is thus that there is no Self that precedes the Spirit’s “self-alienation”: the very process of alienation generates the “Self” from which Spirit is alienated and to which it then returns. … Spirit’s self-alienation is the same as, fully coincides with , its alienation from its Other (nature), because it constitutes itself through its “return-to-itself” from its immersion in natural Otherness. Spirit’s return-to-itself creates the very dimension to which it returns. What this means is that the “negation of the negation ,” the “return-to-oneself” from alienation, does not occur where it seems to: in the negation of the negation, Spirit’s negativity is not relativized, subsumed under an encompassing positivity; it is, on the contrary, the “simple negation” which remains attached to the presupposed positivity it has negated, the presupposed Otherness from which it alienates itself, and the negation of the negation is nothing but the negation of the substantial character of this Otherness itself, the full acceptance of the abyss of Spirit’s self-relating which retroactively posits all its presuppositions. In other words, once we are in negativity, we can never leave it and regain the lost innocence of the origins; in the “negation of the negation” the origins are truly lost, their very loss is lost, they are deprived of the substantial status of that which has been lost. Spirit heals its wound not directly, but by getting rid of the full and sane Body into which the wound was cut. It is in this precise sense that, according to Hegel, “the wounds of the Spirit heal, and leave no scars behind.” His point is not that Spirit heals its wounds so perfectly that, in a magical gesture of retroactive sublation, even the scars disappear; the point is rather that, in the course of the dialectical process, a shift of perspective occurs which makes the wound itself appear as its opposite— the wound itself is its own healing when seen from another standpoint.
