But please don’t take this as a pretence for inaction and hopelessness!

What does the entire history of socialism and of all modern revolutions show us? The first spark of class struggle in Europe, the revolt of the silk weavers in Lyon in 1831, ended with a heavy defeat; the Chartist movement in Britain ended in defeat; the uprising of the Parisian proletariat in the June days of 1848 ended with a crushing defeat; and the Paris commune ended with a terrible defeat. The whole road of socialism – so far as revolutionary struggles are concerned – is paved with nothing but thunderous defeats. Yet, at the same time, history marches inexorably, step by step, toward final victory! Where would we be today without those “defeats,” from which we draw historical experience, understanding, power and idealism? Today, as we advance into the final battle of the proletarian class war, we stand on the foundation of those very defeats; and we can['t] do without any of them, because each one contributes to our strength and understanding.

The revolutionary struggle is the very antithesis of the parliamentary struggle. In Germany, for four decades we had nothing but parliamentary “victories.” We practically walked from victory to victory. And when faced with the great historical test of August 4, 1914, the result was the devastating political and moral defeat, an outrageous debacle and rot without parallel. To date, revolutions have given us nothing but defeats. Yet these unavoidable defeats pile up guarantee upon guarantee of the future final victory.

(It’s a short pamphlet and a very worthy and educating read!)
