"At any point the course of the Revolution could be diverted by a chance happening or an individual decision determined by a freak of personal character. No adequate general history of the Revolution can fail to bring before our eyes a host of individuals, marking with their own idiosyncrasies the events in which they participated. The records are so ample that the deeds and personalities of lesser men as well as of the great stand out clearly. At the same time, the historian whose bias lies in the detection of great impersonal forces can write the history of the Revolution in quite different terms. It would be a mistake to suppose that either approach is exclusively right. The right approach is determined only by the nature of the questions the historian is asking and the right answer by the material of which he asks them."
