Why do people invest so much in systems of thought? Why should somebody be a Christian or a Hindu? Why should somebody be a communist -- for what? There is a reason, a great reason too. Everybody is confused, and so somebody is needed to supply you with certainty. He can be the pope or he can be Mao Zedong, he can be Karl Marx or he can be Manu or Moses -- anybody will do. And whenever there are great times of crisis, any stupid person who has the stubbornness to shout, to argue, who can pretend certainty, will become your leader. That's how Adolf Hitlers, Josef Stalins and Mussolinis became important people.
