The road to power
Karl Kautsky

Friends and enemies of the Socialists agree upon one thing, and that is that they constitute a revolutionary party. But unfortunately the idea of revolution is many-sided, and consequently the conceptions of the revolutionary character of our party differ very greatly. Not a few of our opponents insist upon understanding revolution to mean nothing else but anarchy, bloodshed, murder and arson. On the other hand there are some of our comrades to whom the coming social revolution appears to be nothing more than an extremely gradual, scarcely perceptible, even though ultimately a fundamental change to social relations, much of the same character as that produces by the steam engine.
