  I develop Rafael D. Sorkin's proposal that a partially ordered process of the
birth of spacetime atoms in causal set quantum gravity provides an objective
physical correlate of our perception of time passing. I argue that one cannot
have a fully objective, external 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.
