It has been rightly said that all that remains of a biography is the character of the biographee. And we see this especially in examples that would seem to contradict the rule: in the biography of men who have left an intellectual legacy. Of these men, who made their mark by something other than practical actions, after analyzing their lives we retain the image of what they were like in the practical world, the decisions they made, their temperament and their daily lives. We remember how they lived. We remember the libertine, the consequent, the sullen and the scoundrel. All of this teaches us a lot and establishes an inseparable link between the imaginative and the real.
