Consider the following:
"The state of nature need not be a state in which we achieve coordination equilibria conforming to a regularity. Certainly Hobbes's state of nature is not: battles in the war of all against all do not result in equilibria (since the loser will wish he had adopted a different strategy), let alone coordination equilibria." -- Conventions, p. 95
The first part of this conclusion seems curious to me: In a Hobbesian state of nature, if some big guy shows up, kicks my butt, and takes my stuff, what "different strategy" would I wish I had adopted? "Don't get your butt kicked"?
