is in this process that memory consists; and the memory is the Belief. No obscurity rests on any part of this process, except the idea of _self_, which is reserved for future analysis. The fact, in the mean time, is indisputable; that, when the idea of a sensation, which I have formerly had, is revived in me by association, if it calls up in close association the idea of myself, there is memory; if it does not call up that idea, there is not memory; if it calls up the idea of myself, it calls up the idea of that train of states of consciousness which constitutes the thread of my existence; if it does not call up the idea of myself, it does not call up the idea of that train, but some other idea. A sensation remembered, then, is a sensation placed, by association, as the consequent of one feeling and the antecedent of another, in that train of feelings which constitute the existence of a conscious being. All this will be more evident, when what is included in the notion of Personal Identity is fully evolved. The case of Belief in past existences which have not been the object of our senses, resolves itself into the belief, either of testimony, or of the uniformity of the laws of nature; both of which will, after a few intervening expositions, be fully explained. 3. The process which we denote by the words, {361} "Belief in future events," deserves, on account of its importance, to be very carefully considered. That it is a complex process, will very speedily appear. Our endeavour shall be to resolve it into its elements; in doing which, we shall see whether it consists wholly of the elements with which we have now become familiar, or whether it is necessary to admit the existence of something else. I believe that, to-morrow, the light of day will be spread over England; that the tide will ebb and flow at London-bridge; that men, and houses, and waggons, and carriages, will be seen in the streets of this metropolis; that ships will sail, and coaches arrive; that shops will be opened for their customers, manufactories for their workmen, and that the Exchange will, at a certain hour, be crowded with merchants. Now, in all this, what is involved? First of all, in the Belief of any future event, there is, of course, involved the idea of the event. It will be immediately understood, from what has been already adduced, that there can be no Belief in any existence, without an idea of that existence. If I believe in the light of day to-morrow, I must have an idea of it; if I believe in the flux and reflux of the water at London-bridge, I must have ideas of those several objects; and so of all other things. In the next place; as it has already been shewn, that we cannot call up any idea by willing it; and that none of our ideas comes into existence but by association; the idea which forms the fundamental part of Belief is produced by association. Ideas and association, then, are necessary parts of belief.
