“What are the facts? Again and again and again – what are the facts? Shun wishful thinking, ignore divine revelation, forget what “the stars foretell,” avoid opinion, care not what the neighbors think, never mind the unguessable “verdict of history” – what are the facts, and to how many decimal places? You pilot always into an unknown future; facts are your single clue. Get the facts!”
― Robert Heinlein

“Love is that condition in which the happiness of another person is essential to your own.”
― Robert A. Heinlein, Stranger in a Strange Land

“There ain't no such thing as a free lunch.”
― Pierre Dos Utt, Tanstaafl: A Plan for a New Economic World Order

“Let's just say that if complete and utter chaos were lightning, then he'd be the sort to stand on a hilltop in a thunderstorm wearing wet copper armor and shouting 'All Gods are bastards.”
― Terry Pratchett
