The power of an idea

"it is a proven truth that an idea, no matter what form it assumes, has the power of making us come together, of making us modify our feelings and modes of behaviour and of exercising a constraint over us just as much as any external condition. It matters little if it appears irrational, dissentient, and even having undergone censorship."

-Serge Moscovici
