Apologies in advance! :) Even 1p viewpoints don't move through space-time. That was Hermann Weyl's mistake, or at least sloppy phrasing, which seems to have led to generations of people thinking that their minds are "moving through space-time" like the man squeezed between two plates on a train in "The Sirens of Titan" (if I remember correctly). But, at least according to SR, nothing moves through space-time, not even minds. This is where the "capsule theory of identity" come in. We have the impression that our minds move through time (or that time flows) because we only have memories of the past - but that's all there is to it, at least according to SR. -- You received this message because you are subscribed to the Google Groups "Everything List" group.
