The truth is what survives being challenged by the truth, or less paradoxically, the truth that endures is the remainder of the truth that destroys. The truth, however, may be that no truth endures, but we are never in a position to say so. Metaphysically, which means here in the context of our most all-embracing and un-negotiable sense of reality - or the last reality tested by suffering, dispossession and death - truth admits time and succession, is forced to do so by the very time-bound nature of these limit experiences, and hence the mode of destruction which is supervention cannot be foreclosed. In time it is always possible for one reality to be followed by a different reality, far beyond all hope. Personal or psychological truth is destroyed in a different way since it is tied to a subject and grounded on a perspective. Its centrality is not the same as its truth, but it cannot maintain a claim upon truth - even that it has a truth to claim but which currently eludes it - if it loses its centrality. To overturn a truth claim by a subject it is enough to overturn the subject, which means his assumption of centrality, and the most effective way to do this is by another subject with another centre. So when I resolve to be true to myself, to endeavour to honestly admit my own motives, at least in the privacy of my mind, I immediately come against my own lack of any clear foundation, my ungroundedness and essential relativity, the internal register of the destructive Leninist interrogation, "Who, whom?"
