"We are not dealing with a simple economic doctrine but with a new world outlook."

"The need of a constantly expanding market for its products chases the bourgeoisie over the whole surface of the globe. It must nestle everywhere, settle everywhere, establish connections everywhere."

"What the bourgeoisie therefore produces, above all, are its own grave-diggers. Its fall and the victory of the proletariat are equally inevitable."

"The more the economic conditions of society are subjected to the control of the individual, the more will the individual be free."

"The whole of human history is a process of development from the lower to the higher, from the simple to the complex."
