Well, as well as the question of what constitutes the qualitative
character of such snapshots, one might also wonder about the curious
fact that such 'frozen' capsules nonetheless appear to us as
possessing internal temporal duration and differentiation. This seems
to appeal simultaneously to aspects of both flux and block models of
time whilst being entirely consistent with neither.
