The religious world is but a reflex of the real world.

Capital is reckless of the health or length of life of the laborer, unless under compulsion from society.

He who before was the money owner, now strides in front as capitalist; the possessor of labor-power follows as his laborer. The one with an air of importance, smirking, intent on business; the other hesitant, like one who is bringing his own hide to market and has nothing to expect but a hiding.

The more of himself man attributes to God, the less he has left in himself.

The existence of the state is inseparable from the existence of slavery.

The ruling ideas of each age have ever been the ideas of its ruling class.

Let the ruling classes tremble at a communist revolution. The proletarians have nothing to lose but their chains. They have a world to win. Workingmen of all countries, unite!
