The mere collection of the cross-fire of vituperation from modern partisans is useful as teaching us distrust in any one-sided view of the past.

History will have left half its work undone, if it does not teach us humility and caution. But essential truth can almost always be found—truth of all kinds can with due research be usually found: she lies, no doubt, in a well; but we may be sure that she is there, if we dig deep enough. In this labour teachers and students must all work together. What one cannot discover, many at work on the same point can often prove beyond doubt. Like Napoleon and his comrades, when lost in the quicksands of the Red Sea, let each ride out a different way, and the first that comes to firm ground, bid the others halt and follow him.
