As Raymond Geuss states in the introduction to his 2008 Philosophy and Real Politics (PP), his book "wishes to suggest the possibility that there might be a viable way of thinking about politics that is orthogonal to the mainstream of contemporary analytic political philosophy" (p 18). Politics and the Imagination (PI) is plausibly understood (though does not explicitly introduce itself) as a sequel to PP. PI is a wide-ranging collection of essays with which readers will come to terms more easily if they have some sense of how they fit in with Geuss' attempt to provide such a non-mainstream approach. Therefore I begin with a few recollections of, and comments on, that earlier discussion.
