Put not your trust in princes,” said King David some three thousand years ago, and he knew what he was talking about. But if biographers were to take his admonition to heart, they would go broke—and we would be the worse for it. So long as humans measure their own lives by those of the extraordinary, so long will they find the stories of the great in every field worthy of contemplation. Historians of late have made much of the oppressive shadow cast by the giants of the ages; the “new” historians prefer to focus on the multitude of obscure lives that make up a total picture of historical times. In viewing history from the bottom up, they have done innovative and useful work by illuminating the lives of women, minorities, workers, farmers, and others. But if you asked those neglected groups themselves, they would probably say it was the extraordinary among them who are of the most interest.
