... For ancient heroes the exhaustive method is possible: all that can be known of them is contained in a few short passages of Greek and Latin, and it is quite possible to say whatever can be said about every one of these; the result would not be unreasonably bulky, though it might be dull. But in the case of men who have lived in the thick of the crowded modern world, no such course is admissible; overmuch may be said, and we must choose what we will say. Biographers, however, are rarely bold enough to adopt the selective method consistently. They have, we suspect, the fear of the critics before their eyes.
