Al-Afghani viewed revolutions as naturally propagating beyond their origin

Evidence

I do not know what the result would be if the Sudan fell wholly into Muhammad Ahmad’s possession and he set up government over those vast lands, with no way left to him but to continue on his path and propagate his message among all the Arab tribes, with all of his capabili- ties. And he would not stop there but mobilize his dense armies up to the borders of Upper Egypt, perhaps; rather it is likely he will do this, as it has never happened that the flames of revolution did not hurry, by their very nature, along the tracks of their natural path. — Eve M.
