"The masses have never thirsted after truth. They turn aside from evidence that is not to their taste, preferring to deify error, if error seduce them. Whoever can supply them with illusions is easily their master; whoever attempts to destroy their illusions is always their victim.
Isolated, he may be a cultivated individual; in a crowd, he is a barbarian — that is, a creature acting by instinct. He possesses the spontaneity, the violence, the ferocity, and also the enthusiasm and heroism of primitive beings.
Civilisations (e.g. Babylon, Ancient Egypt, Roman Empire) as yet have only been created and directed by a small intellectual aristocracy, never by crowds. Crowds are only powerful for destruction. Their rule is always tantamount to a barbarian phase. A civilisation involves fixed rules, discipline, a passing from the instinctive to the rational state, forethought for the future, an elevated degree of culture — all of them conditions that crowds, left to themselves, have invariably shown themselves incapable of realising. In consequence of the purely destructive nature of their power crowds act like those microbes which hasten the dissolution of enfeebled or dead bodies. When the structure of a civilisation is rotten, it is always the masses that bring about its downfall.”
