So far I have run across David Gordon's very good treatment of one aspect of Thomas Nagel's project in Mind and Cosmos (Oxford 2012) entitled Moral Realism vs. Evolutionary Biology? Other than that it has been slim pickin's when it comes to informed, nontendentious discussions of Nagel's latest. I've heard that Plantinga is writing a review, but it hasn't yet appeared to my knowledge.
A certain blogger famous for his academic gossip site, arguably the preeminent such site in the whole of the philososphere, published a hit piece in a certain left wing publication but it is not worth reading. (Antecedent of 'it' left ambiguous: take it both ways.)
ComBox is open should anyone know of any good reviews or discussions of Nagel's book. I'm on p. 76 and will post something in the next few days.
Here are excerpts from a Gordon review of an earlier Nagel book.
