Saving Robert Heinlein

Gary Westfahl: Thus, I wish to argue instead that there were, in fact, only two periods in Heinlein’s career: from 1939 to 1957, Heinlein wrote science fiction, and from 1958 until his death in 1988, Heinlein wrote satires of science fiction. Or, if that language seems too strong, say that from 1939 to 1957, Heinlein took his science fiction very seriously, and after that, he no longer took his science fiction seriously.
