Yes, I can. Actually Herbert himself did have a good (taboo) thought in Dune with his Golden Path idea, that to save humanity it must endure a tyrant for thousands of years. Asimov's Foundation series had a lot to say about the natural ebb and flow of civilization on a long time scale, a very Buddhist view. He also had a lot to say about the nature of general AI, and the relationship to such beings with humans, in his Robot novels (I'm most familiar with the Daniel R Olivaw novels, e.g. Caves of Steel). Of course, when it comes to society, politics, and technology, Neal Stephenson, in both Snowcrash and The Diamond Age, has a lot of great philosophical ideas. Like a good author he shows, and doesn't tell us about his ideas. The character Raven in Snowcrash, for example, expresses the now pretty common understanding that individuals, armed with technology, can challenge states (e.g. bin Laden). There are lots and lots of other authors and ideas.
