There are more ideas on earth than intellectuals imagine. And these ideas are more active, stronger, more resistant, more passionate than politicians think. We have to be there at the birth of ideas, the bursting outward of their force: not in books expressing them, but in events manifesting this force, in struggles carried on around ideas, for or against them. Ideas do not rule the world. But it is because the world has ideas... that it is not passively ruled by those who are its leaders or those who would like to teach it, once and for all, what it must think.
