Joseph J. Ellis said this quote

Washington not only fit the bill physically, he was also almost perfect psychologically, so comfortable with his superiority that he felt no need to explain himself. (As a young man during the French and Indian war he had been more outspoken, but he learned from experience to allow his sheer presence to speak for itself.) While less confident men blathered on, he remained silent, thereby making himself a vessel into which admirers for their fondest convictions, becoming a kind of receptacle for diverse aspirations that magically came together in one man.
