I am not quite sure yet how to fit this definition of neoclassical liberalism into what I think of as my Hayekian rule utilitarianism, but it is surely worth thinking about. I do think that "high liberals" often downgrade economic liberties both because they sometimes do not understand much economics and because their personal experience outside the academic and government worlds is often limited.
I wish I had more time to read philosophy. I read a fair amount of political philosophy in my undergrad and early (i.e. pre-Heckman) graduate student days but not very much since then.
