Discovery consists of seeing what everybody has seen and thinking what nobody has thought.
Seeking to know is only too often learning to doubt. Nothing is more dangerous than an idea, when it s the only one we have. Emile August Chartier, 1868-1951 Big ideas are so hard to recognize, so fragile, so easy to kill. An invasion of armies can be resisted, but not an idea whose time has come. We never do anything well till we cease to think about the manner of doing it.
