Starship Troopers

The Wikipedia entry of the day relates to Robert A. Heinlein's novel Starship Troopers. I was impressed by the novel when I was 14, less impressed when I was 20, and more impressed today. Heinlein wrote a good story and rendered the didactic and tendentious as palatable. I have never been clear on whether Starship Troopers represented the real stream of his thought, or whether the altered consciousness hippie ethic of Stranger in a Strange Land was closer to his heart.
