" Quite unlike conscious memories from the time of maturity, they are not fixed at the moment of being experienced and afterwards repeated, but are only elicited at a later age when childhood is already past; in the process they are altered and falsified, and are put into the service of later trends, so that generally speaking they cannot be sharply distinguished from phantasies. Their nature is perhaps best illustrated by a comparison with the way in which the writing of history originated among the peoples of antiquity. As long as a nation was small and weak it gave no thought to the writing of its history. Men tilled the soil of their land, fought for their existence against their neighbours, and tried to gain territory from them and to acquire wealth. It was an age of heroes not of historians. Then came another age, an age of reflection: men felt themselves to be rich and powerful, and now felt a need to learn where they had come from and how they had developed. "
