The existing legal constitution is nothing but the product of a revolution. Revolution is the act of political creation in the history of classes, while constitutional legislation is the expression of the continual political vegetation of a society.

Social democracy... is only the advance guard of the proletariat, a small piece of the total working masses; blood from their blood, and flesh from their flesh.

Democracy is indispensable, not because it renders superfluous the conquest of political power by the proletariat, but, on the contrary, because it makes this seizure of power both necessary and possible.

The more that social democracy develops, grows, and becomes stronger, the more the enlightened masses of workers will take their own destinies, the leadership of their movement, and the determination of its direction into their own hands.
