Robert A. Heinlein (writing about Stranger In A Strange Land)

I was asking questions. I was not giving answers. I was trying to shake the reader loose from some preconceptions and induce him to think for himself, along new and fresh lines. In consequence, each reader gets something different out of that book because he himself supplies the answers. If I managed to shake him loose from some prejudice, preconception, or unexamined assumption, that was all I intended to do. A rational human being does not need answers, spoon fed to him on "faith," he needs questions to worry over—serious ones. The quality of the answers then depends on him... But anyone who takes that book as answers is cheating himself. It is an invitation to think—not to believe.
