"No book can eradicate religion from the minds of masses who are crushed by capitalist hard labour, and who are at the mercy of the destructive forces of capitalism, until those masses themselves learn to fight this root of religion, fight the rule of capital in all its forms, in a united, organised, planned and conscious way. Does this mean that educational books against religion are harmful or unnecessary? No, it means that Social-Democracy’s atheist propaganda must be subordinated to its basic task—the development of the class struggle of the exploited masses against the exploiters."
