Anthony objects that where one was born is a matter of biology and circumstance. Well, if it is a necessary or logical truth that the referent of 'I' or 'myself' is identical with my body, then of course. But suppose it isn't – and I can't see any reason why it should be. Suppose, for example, that reincarnation is possible. That means that I, me, myself could be re-born after my bodily death into a different body, and some indeterminate future point in time. Then biology could not explain why I was reborn with that particular body, in that particular place, at that particular time. Obviously biology would explain why that body had the parents it happened to have, and why it had the particular DNA it had. But biology could not explain why I, the person I am referring to now by the personal pronoun 'I', was reborn in that body.
Contra: perhaps it isn't logically possible, on account of the principle of sufficient reason. The principle says that there must always be a reason why something happens one way rather than another. But there is no conceivable reason why I should be reborn in one body rather than another. To be sure, there are religious views about karma that attempt to give reasons for a particular kind of rebirth. But these are hardly scientific, i.e. as far as I know they are not based in unassailable principles known per se and aided by logic.
Reply: But then we are back to the original question: if there is no reason to explain why anyone should be reborn - i.e. born again – in one body rather than another, there is no reason to explain why anyone is born – i.e. born the first time – in one body rather than another. The principle of sufficient reason does not, on its own, establish that reincarnation is logically impossible.
