It needs intelligence to be happy, and people are taught to remain unintelligent. The society does not want intelligence to flower. The society does not need intelligence; in fact it is very much afraid of intelligence. The society needs stupid people. Why? -- because stupid people are manageable. Intelligent people are not necessarily obedient -- they may obey, they may not obey. But the stupid person cannot disobey; he is always ready to be commanded. The stupid person needs somebody to command him, because he has no intelligence to live on his own. He wants somebody to direct him; he seeks and searches his own tyrants.
Politicians don't want intelligence to happen in the world, priests don't want intelligence to happen in the world, generals don't want intelligence to happen in the world. Nobody really wants it. People want everybody to remain stupid, then everybody is obedient, conformist, never goes outside the fold, remains always part of the mob, is controllable, manipulatable, manageable.
