" It is terrible at times to think of the power that strong conviction combined with extreme narrowness of mind gives a man possessing prestige. It is none the less necessary that these conditions should be satisfied for a man to ignore obstacles and display strength of will in a high measure. Crowds instinctively recognise in men of energy and conviction the masters they are always in need of. "
― Gustave Le Bon , سيكولوجية الجماهير
