For the pedant, dates are deities, worthy of worship, but for the true social historian, they are minutiae only, a shorthand, convenient reminders and no more. You do not ask a Titanic survivor, 'Let me see now, just exactly when was that?' You ask him this: 'What was it like? How did you feel?' And that is the job of the social historian: to make the past vibrant for the present; to emotionally involve those of us who were not there. And to make us understand.
