TANSTAAFL! There ain't no such thing as a free lunch!
- Robert Heinlein The Moon Is a Harsh Mistress
Man is what he is, a wild animal with the will to survive, and (so far) the ability, against all competition. Unless one accepts that, anything one says about morals, war, politics -- you name it -- is nonesense. Correct morals arise from knowing what Man is -- not what do-gooders and well-meaning old Aunt Nellies would like him to be.
-Robert Heinlein Starship Troopers (Great book, butchered in film)
Violence, naked force, has settled more issues in history than has any other factor, and the contrary is wishful thinking at its worst.
-Robert Heinlein Starship Troopers
Yeah, I'm a Heinlein fan. Partly because many of his books have some great (if thought provoking) quotes.
