Children, savages and true believers remember far less what they have seen than what they have heard.

You can discover what your enemy fears most by observing the means he uses to frighten you.

All mass movements strive, therefore, to interpose a fact-proof screen between the faithful and the realities of the world. They do this by claiming that the ultimate and absolute truth is already embodied in their doctrine and that there is no truth nor certitude outside it.
