Revolution did not necessarily involve sanguinary strife. It was not a cult of bomb and pistol. They may sometimes be mere means for its achievement.
A rebellion is not a revolution. It may ultimately lead to that end.
Let me announce, with all the strength at my command, that I am not a terrorist and I never was, expect perhaps in the beginning of my revolutionary career. And I am convinced that we cannot gain anything through those methods.
