William Roberts was first introduced to me as a great source for understanding Compt's role in the dialectical theory and positivism. But he was only on the radio and I have difficulty downloading shows. I'm listening to his interview with Melodee (truthquest) though right now and it's coming straight in with no blips. He has his own show now and there's a link to some material he's published on the UN and Local Agenda 21 (which I didn't realize he'd started publishing yet). Roberts comes highly recommended by a very aware and experienced follower of the emerging global synthesis. Roberts was a regular guest on Freedom 21 Santa Cruz radio with host Michael Shaw for years.
