"The ruling ideas of each age have..." - Quote by Karl Marx

“The need of a constantly expanding market for its products chases the bourgeoisie over the entire surface of the globe. It must nestle everywhere, settle everywhere, establish connections everywhere. The bourgeoisie has, through its exploitation of the world market, given a cosmopolitan character to production and consumption in every country. To the great chagrin of reactionaries, it has drawn from under the feet of industry the national ground on which it stood.”

“Misery motivates, not utopia.”

“One of the most difficult tasks confronting philosophers is to descend from the world of thought to the actual world.”

“We do not yet trust the unknown powers of thought. Whence came all these tools, inventions, book laws, parties, kingdoms? Out of the invisible world, through a few brains. The arts and institutions of men are created out of thought. The powers that make the capitalist are metaphysical, the force of method and force of will makes trade, and builds towns.”

“You cannot go against nature. She is stronger than the strongest of men. We can permit ourselves some liberties, but in details only.”

“Such power!" Adelaida cried all at once, peering greedily at the portrait over her sister's shoulder. "Where? What power?" Lizaveta Prokofyevna asked sharply. "Such beauty has power," Adelaida said hotly. "You can overturn the world with such beauty.”

“If we took over Britain, then we'd have the job of cleaning up the bourgeoisie and keeping people in a revolutionary state of mind.”

“Methods of thought which claim to give the lead to our world in the name of revolution have become, in reality, ideologies of consent and not of rebellion.”

“The truth is, some of these comments, when you actually ask 'well, this is based on what? This notion that Obama's a socialist, for example?' Nobody can really give you a good answer.”
