It is always admirable when the historian or biographer manages to clearly show us the man behind the work. This is a very difficult task, full of pitfalls that can jeopardize any effort to understand. But when successful, it gives the reader invaluable material, not only in terms of the connection between life and work on which it depends, but also in terms of the larger picture of existence. We see there habits, beliefs, conflicts, ideas, predispositions, and whether we identify with them or not, we increase our arsenal of possibilities, we understand life better. In short, this material enables us to learn from the example of a real man.
