  I will argue, pace a great many of my contemporaries, that there's something
right about Boltzmann's attempt to ground the second law of thermodynamics in a
suitably amended deterministic time-reversal invariant classical dynamics, and
that in order to appreciate what's right about (what was at least at one time)
Boltzmann's explanatory project, one has to fully apprehend the nature of
microphysical causal structure, time-reversal invariance, and the relationship
between Boltzmann entropy and the work of Rudolf Clausius.
