If there had been no real heroes there would have been created imaginary ones, for men cannot live without them. The hero is just as necessary as the farmer, the sailor, the carpenter and the doctor; society could not get on without him. There have been a great many different kinds of heroes, for in every age and among every people the hero has stood for the qualities that were most admired and sought after by the bravest and best; and all ages and peoples have imagined or produced heroes as inevitably as they have made ploughs for turning the soil or ships for getting through the water or weapons with which to fight their enemies.
