 Another difference that may be insisted on is this, that I shall have a real sensible interest in my own future feelings which I cannot possibly have in those of others. I must therefore as the same individual have the same necessary interest in them at present. This may either proceed on the supposition of the absolute, metaphysical identity of my individual being, so that whatever can be affirmed of that principle at any time must be strictly and logically true of it at all times, which is a wild and absurd notion; or it may refer to some other less strict connection between my present and future self, in consequence of which I am considered as the same being, the different events and impressions of my life constituting one regular succession of conscious feelings. In this sense, the saying that I have a general interest in whatever concerns my future welfare in fact amounts to no more than affirming, that I shall have an interest in that welfare, or that I am nominally and in certain other respects the same being who will hereafter have a real interest in it. The reason why we are so ready to attribute a real identity of interests to the same person is, that we have an indistinct idea of extended consciousness, and a community of feelings as essential to the same thinking being; so that whatever interests me at one time must interest me, or be capable of interesting me, at other times. Now this continued consciousness only serves to connect my past with my present impressions. It only acts retrospectively. I have not previously the same sympathy with my future being that I have with my past being, nor consequently the same natural or necessary interest in my future welfare that I have in my past. Lastly, it may be said, that there is something in the very idea of pleasure or pain as affecting myself which naturally excites a lively unavoidable interest in my mind. I cannot conceive how
