Johnson is wise, Boswell foolish; Johnson warns and abstains, Boswell plunges; Johnson is rather a great man writing than a greatwriter, Boswell is a great writer and an ordinary man; and they are two of a kind, abysmal melancholics and compulsive socializers, afraid of solitude and afraid of death and dissolution, victims of themselves, meant for each other, needing each other, needing evidence and arguments (Boswell is a lawyer, Johnson magisterially dictates to him some of his briefs), making beautiful models of rational discourse out of the useful substance of all they know.
