I've been rereading Robert A. Heinlein's Sixth Column (written as something of a command performance for John W. Campbell). It's as racist as ever -- whew, WW II was over even in the Pacific, but I guess not that over? -- and it's got something else going on, too: a not-very-well-buried scathing contempt for anyone using science to fake up a religion under any but the most dire of circumstances. Gosh, I wonder what that possibly could have been about?
