_First_, This notion is absolutely contradictory to that certain conviction, which necessarily and every moment rises within us, when we turn our thoughts upon ourselves, when we reflect upon what is past, and look forward upon what is to come. All imagination of a daily change of that living agent which each man calls himself, for another, or of any such change throughout our whole present life, is entirely borne down by our natural sense of things. Nor is it possible for a person in his wits to alter his conduct, with regard to his health or affairs, from a suspicion, that, though he should live to-morrow, he should not, however, be the same person he is to-day. Yet, if it be reasonable to act, with respect to a future life, upon the notion that personality is transient, it is reasonable to act upon it, with respect to the present. Here then is a notion equally applicable to religion and to temporal concerns. Every one sees and feels the inexpressible absurdity of it in the latter case; therefore, if any can take up with it in the former, this cannot proceed from the reason of the thing, but must be owing to inward unfairness, and secret corruption of heart. _Secondly_, It is not an idea, or abstract notion, or quality, but a _being_ only, which is capable of life and action, of happiness and misery. Now all beings confessedly continue the same, during the whole time of their existence. Consider then a living being now existing, and which has existed for any time alive. This living being must have done and suffered and enjoyed, what it has done and suffered and enjoyed formerly, (this living being, I say, and not another) as really as it does and suffers and enjoys, what it does and suffers and enjoys this instant. All these successive actions, enjoyments, and sufferings, are actions, enjoyments, and sufferings, of the same living being. And they are so, prior to all consideration of its remembering or forgetting: since remembering or forgetting can make no alteration in the truth of past matter of fact. And suppose this being endued with limited powers of knowledge and memory, there is no more difficulty in conceiving it to have a power of knowing itself to be the same living being which it was some time ago, of remembering some of its actions, sufferings, and enjoyments, and forgetting others, than in conceiving it to know or remember or forget any thing else.
