I develop Rafael D. Sorkin's heuristic that a partially ordered process of
the birth of spacetime atoms in causal set quantum gravity can provide an
objective physical correlate of our perception of time passing. I argue that
one cannot have an external, fully objective picture of the birth process
because the order in which the spacetime atoms are born is a partial order. I
propose that live experience in causal set theory is an internal view of the
objective birth process in which events that are neural correlates of
consciousness occur. In causal set theory, what ``breathes fire'' into a neural
correlate of consciousness is that which breathes fire into the whole universe:
the unceasing, partially ordered process of the birth of spacetime atoms.Comment: 21 pages, 1 figur
