Power can sometimes be won or maintained without violence, but never without fraud, because it is necessary to make use of the masses, and the masses would not co-operate if they knew that they were simply serving the purposes of a minority. In each great revolutionary struggle the masses are led on by vague dreams of human brotherhood, and then, when the new ruling class is well established in power, they are thrust back into servitude. This is practically the whole of political history, as Burnham sees it.
