    I think waking up somewhere else would count strongly against
    being the closest continuation.

What if, while both are asleep, the original is moved to another location and the copy moved to the original's bed?

That would help, but there's an implicit assumption that asleep=mindless. Anesthetic would make a better example. But won't both the original and the copy find himself in a disjoint location incompatible with where he was before?

I think part of the problem here is that the first-person impression is taken to be definitive. Since the closest continuer theory weights bodily continuity fairly highly in the metric whereby 'closest' is to be determined, what happens to your body, whether or not you are conscious of it, is an important consideration.

It was my understanding that closest continuer was to be judged entirely in terms of conscious thoughts, e.g. memories. Of course these include memories of ones body so noticeable physical changes would count against, but discontinuity that was not noticeable wouldn't. Causal connection doesn't count because the idea is to explain everything, including causality in terms of consciousness. I'm not even sure the theory is coherent. I want to ask; continuer of what? It seems to intuitively rest on the idea a being or soul that *must* continue and so must attach to some best vehicle.

That might be Bruno's idea -- he defines personal identity solely in terms of memories of one's previous selves. In fact, in the way you put it here, such a theory seems to be inherently dualist.

But in my opinion, Bruno's definition is too narrow, and self-serving. The closest continuer theory as discussed in the philosophical literature on personal identity is much broader. It takes account of all features of a person -- memories, bodily features, environment, causal connections, values, temperament, personality, skills, etc, etc. The definition of a 'person' is seen as irreducibly multi-dimensional. Of course, that means that one must define a metric across those dimensions in order to determine what is 'closest'. The metric is not absolutely specified by the theory, and I think it can, in fact, be flexible, in that one weighting of factors might be more appropriate in one setting than in another.

The point is that one should capture as much of the notion of personal identity that we use everyday as is possible. In particular, it should take account of those difficult cases where memory is lost or impaired in one way or another. Bruno's definition is just too restrictive to be of any use in the real world.

But maybe Stathis should explain what he means by the theory.
