  • Indeed, the platitude is about the responsibility of persons, but four-dimensionalism offers only a solution regarding the responsibility of person-stages (Ibid.; see also Parfit 1976).

    Personal Identity and Ethics

  • On any view of personal identity other than four-dimensionalism, recall, I cease to exist if I undergo fission.

  • Now these are just standard puzzles for four-dimensionalism about persons (see Olson 1997b, van Inwagen 2002, and the entry on personal identity).

  • "I feel a bit apologetic for retaining the term 'four-dimensionalism' as a name for the thesis that things have temporal parts. This is one standard usage of the term, but the term is also sometimes used (particularly in Australia) for the B-theory of time, or for the conjunction of the B-theory and the doctrine of temporal parts. The term also has the disadvantage of not wearing its meaning on its sleeve. For example, what I call four-dimensionalism implies the existence of instantaneous objects: temporal slices of spacetime worms. Since temporal slices have non-zero extension in only the three spatial dimensions, someone not familiar with the debate might expect me to be a three-dimensionalist. Despite these shortcomings, my terminology is familiar and entrenched enough to be useful, if handled with care."
