Great men are necessary for our life, in order that the movement of world history can free itself sporadically, by fits and starts, from obsolete ways of living and inconsequential talk.
The more recently power has originated, the less it can remain stationary - first because those who created it have become accustomed to rapid further movement and because they are and will be innovators per se; secondly, because the forces aroused or subdued by them can be employed only through further acts.
