“The sight of so many guns, mostly deer rifles and duck guns but with a smattering of black rifles and riot shotguns, made him glad that this was going down in a rural area where people still had their heads screwed on right about personal defense.”
― Larry Correia, The Monster Hunters

“You could trust numbers, except perhaps for pi, but he was working on that in his spare time and it was bound to give in sooner or later.”

“We absolutely must leave room for doubt or there is no progress and there is no learning. There is no learning without having to pose a question. And a question requires doubt. People search for certainty. But there is no certainty. People are terrified — how can you live and not know? It is not odd at all. You only think you know, as a matter of fact. And most of your actions are based on incomplete knowledge and you really don't know what it is all about, or what the purpose of the world is, or know a great deal of other things. It is possible to live and not know.”
― Richard P. Feynman, The Pleasure of Finding Things Out: The Best Short Works of Richard P. Feynman
