“Historically, the errors committed by a truly revolutionary movement are infinitely more fruitful than the infallibility of the cleverest Central Committee.”

“But here is the "ego" of the Russian revolutionary again! Pirouetting on its head, it once more proclaims itself to be the all-powerful director of history — this time with the title of His Excellency the Central Committee of the Social Democratic Party of Russia.”

“A mistake that most people make is to assume that the more followers you can recruit, the better. That's true if you are trying to win an election. A vote is a vote regardless of whether the voter is deeply committed or just barely interested enough to get to the polls. But when you're building a revolutionary movement, the number of people you have is far less important than the quality of your people and the depth of their commitment. Too many lukewarm or otherwise unsuitable people will ruin the movement.”

“It will hardly be denied that a revolution, whatever else it may be, is a phenomenon of the crowd. I have endeavored to approach the historical survey of revolutionary movements from the standpoint of social psychology.”

“Libertarianism is clearly the most, perhaps the only truly radical movement in America. It grasps the problems of society by the roots. It is not reformist in any sense. It is revolutionary in every sense.”

“Without Revolutionary theory, there can be no Revolutionary Movement.”

“Errors of knowledge are not breaches of morality; no proper moral code can demand infallibility or omniscience.”

“Like several other historical personages, Gandhi had a highly complex personality, his teachings, too, are incapable of over-simplified assessments on the lines of his being 'the inspirer of the national movement who roused the masses to anti-imperialist action', 'the counter-revolutionary who did all he could to prevent the development of our national movement on revolutionary lines', etc.”

“Nothing is more natural than mutual misunderstanding; the contrary is always surprising. I believe that one never agrees on anything except by mistake, and that all harmony among human beings is the happy fruit of an error.”

“The aim of science is not to open the door to infinite wisdom, but to set some limit on infinite error.”
