Supposedly, The Obstacle is the Way is in the vein. I haven't read it yet; it's on my list this month though. Supposedly a fairly good read though. It's written by a big PR guy though so who knows.
Have a read of A New Stoicism by Lawrence C Becker [0]. It is quite technical in places but the introductary chapters and the conclusion will do enough to put old Bertie back in his logical positivist box. It's not as if Bertie was a slap, happy old hippy himself.
