“If you didn't predict that something would happen, if it took you completely by surprise, then what you believed about the world when you didn't see it coming, isn't enough to explain [what has happened].”
― Eliezer Yudkowsky, Harry Potter and the Methods of Rationality

“What people really believe doesn't feel like a BELIEF, it feels like the way the world IS.”

“Don’t worry about people stealing your ideas. If your ideas are any good, you’ll have to ram them down people’s throats.”

“Because the way people are built, Hermione, the way people are built to feel inside -" Harry put a hand over his own heart, in the anatomically correct position, then paused and moved his hand up to point toward his head at around the ear level, "- is that they hurt when they see their friends hurting. Someone inside their circle of concern, a member of their own tribe. That feeling has an off-switch, an off-switch labeled 'enemy' or 'foreigner' or sometimes just 'stranger'. That's how people are, if they don't learn otherwise.”
― Eliezer Yudkowsky, Harry Potter and the Methods of Rationality
