i'm not actually recommending any of those authors (except maybe thoreau, who might not fit the "novelist" label anyways), just saying they have written stuff that could be considered subversive.i did read the original foundation trilogy way back, and while i didn't hate them the way sms and dot seem to, i also didn't find them particularly good. if i remember correctly (highly unlikely), some aspects of the story line could be considered subversive, in a way vaguely similar to how dune might be considered somewhat subversive. a stretch...? perhaps. i didn't put all that much thought into it, sorry to say.
