Political and social history are in my view two aspects of the same process. Social life loses half its interest and political movements lose most of their meaning if they are considered separately.
Problems cannot all be solved, for, as they are solved, new aspects are continually revealed: the historian opens the way, he does not close it.
History is full of the dead weight of things which have escaped the control of the mind, yet drive man on with a blind force.
History is not a pattern-book of fossilized ideologies.
