Some analytic philosophers you may have heard of include: Bertrand Russell, Karl Popper, Ludwig Wittgenstein, G.E. Moore, R.M. Hare, A.J. Ayer, Saul Kripke, David Lewis, Edmund Gettier, John Rawls, Robert Nozick, and Nick Bostrom. Many of these philosophers discussed morality and justice a great deal. Others discussed the logical underpinnings of science and mathematics--Popper in particular is highly esteemed by many scientists I've known, and Russell needs no introduction.
EDIT: There are of course many great analytic philosophers I forgot, but I found it worth editing this post to include W.V.O. Quine, in honor of whom we write programs which print their own source code.
This is a large problem not just in Postmodernism but in many areas of modern analytic philosophy as well, especially Philosophy of Mind.
