Most of the people who appear most often and most gloriously in the history books are great conquerors and generals and soldiers, whereas the people who really helped civilization forward are often never mentioned at all. We do not know who first set a broken leg or launched a seaworthy boat, or calculated the length of a year, or manured a field, but we know all about the killers and destroyers. People think a great deal of them, so much so that on all the highest pillars in the great cities of the world you will find the figures of a conqueror of a general or a soldier. And I think most people beliv=eve that the greatest countries are those that have beaten in the battle the greatest number of countries and ruled over them as conquerors.
