“Great men are they who see that spiritual is stronger than any material force, that thoughts rule the world.”

“The ideas of the ruling class are in every epoch the ruling ideas, i.e. the class which is the ruling material force of society, is at the same time its ruling intellectual force. The class which has the means of material production at its disposal, has control at the same time over the means of mental production, so that thereby, generally speaking, the ideas of those who lack the means of mental production are subject to it. The ruling ideas are nothing more than the ideal expression of the dominant material relationships, the dominant material relationships grasped as ideas.”

“I do not say that there are no stronger men than these; but will any one say that there are any men stronger than those men of old who were dominated by their philosophy and steeped in their religion? Whether bondage be better than freedom may be discussed. But that their bondage came to more than our freedom it will be difficult for any one to deny.”

“Speaking very generally, I find that women are spiritually, emotionally, and often physically stronger than men.”

“Three great forces rule the world: stupidity, fear and greed.”

“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 (and because it constantly produces them) 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.”
