feiting identity. A phenomenon A is produced by certain conditions, which then are modified. Upon this, A, wholly or partially, retires from existence, but, on another change, shows itself partly or in full. A disappears into conditions which, even as such, need not persist; but, when the proper circumstances are re-created, A exists once again. Shall we assert that, if so, A’s identity is gone? I do not know on what principle. Or shall we insist that, at least in the meantime, A cannot be said to be? But it seems not clear on what ground. If we take such common examples as a rainbow, or a waterfall, or the change of water into ice, we seek in vain for any principle but that of working convenience. We feel sure that material atoms and their motion continue unaltered, and that their existence, if broken, would be utterly destroyed. But, unless we falsely take these atoms and their motion for ultimate reality, we are resting here on no basis beyond practical utility. And even here some of us are too inclined to lapse into an easy-going belief in the “potential.” But, as soon as these atoms are left behind, can we even pretend to have any principle? We call an organism identical, though we do not suppose that its atoms have persisted. It is identical because its quality is (more or less) the same, and because that quality has been (more or less) all the time there. But why an interval must be fatal, is surely far from evident. And, in fact, we are driven to the conclusion that we are arguing without any rational ground. As soon as an existence in time is perceived to be appearance, we can find no reason why it should not lapse, and again be created. And with an organism, where even the matter is not supposed to persist, we seem to have deserted every show of principle.[1]
