Jonathan Edwards on Personal IdentityThe Works of Jonathan Edwards, Henry Rogers and Sereno Edwards Dwight, eds. (W. Ball: 1839; orig. c. 1703-1758), p. cclxiv.
Identity of person is what seems never yet to have been explained. It is a mistake, that it consists in sameness, or identity, of consciousness — if, by sameness of consciousness, be meant, having the same ideas hereafter, that I have now, with a notion or apprehension that I had had them before; just in the same manner as I now have the same ideas, that I had in time past, by memory. It is possible, without doubt, in the nature of things, for God to annihilate me, and after my annihilation to create another being that shall have the same ideas in his mind that I have, and with the like apprehension that he had them before, in like manner as a person has by memory; and yet I be in no way concerned in it, having no reason to fear what that being shall suffer, or to hope for what he shall enjoy. Can anyone deny, that it is possible, after my annihilation, to create two beings in the Universe, both of them having my ideas communicated to them, with such a notion of their having had them before, after manner of memory, and yet be ignorant one of another; and, in such case, will any one say, that both these are one and the same person, as they must be, if they are both the same person with me. It is possible there may be two such beings each having all the ideas that are now in my mind, in the same manner that I should have by memory, if my own being were continued; and yet these two beings not only be ignorant one of another but also be in a very different state, one in a state of enjoyment and pleasure, and the other in a state of great suffering and torment. Yea, there seems to be nothing of impossibility in the Nature of things, but that the Most High could, if he saw fit; cause there to be another being, who should begin to exist in some distant part of the Universe, with the same ideas I now have, after manner of memory: and should henceforward co-exist with me; we both retaining a consciousness of what was before the moment of his first existence, in like manner; but thenceforward should have a different train of ideas. Will any one say that he, in such a case, is the same person with me, when I know nothing of his sufferings, and am never the better for his joys.
