@ben_crowell_fullerton I cannot speak to intention and motivation.
@bibliolater For the point of view that I think is standard and settled:
Wald, "The Arrow of Time and the Initial Conditions of the Universe," 2005, http://arxiv.org/abs/gr-qc/0507094
Oleg Kupervasser, Hrvoje Nikoliฤ, Vinko Zlatiฤ, "The Universal Arrow of Time," http://arxiv.org/abs/1011.4173v5
@bibliolater I skimmed through the book. It seems odd to me that he never seems to seriously consider what I take to be the mainstream interpretation. We had a low-entropy big bang, for reasons we don't know. That fact defines an arrow of time.
Instead he seems to consider various straw men, such as the claim that thermodynamics all by itself defines an arrow of time (obviously wrong), or that cosmological expansion is somehow coupled to the thermodynamic arrow (why?).
