Context: When facing the realm of life and death in the form of an enemy's sword, one must be firmly settled in mind and body, and not at all intimidated; without providing your opponent the slightest opening, control his mind in a flash and move where you will — straight, diagonally, or in any other appropriate direction.

"Charles Dickens" (1939)
Context: When one reads any strongly individual piece of writing, one has the impression of seeing a face somewhere behind the page. It is not necessarily the actual face of the writer. I feel this very strongly with Swift, with Defoe, with Fielding, Stendhal, Thackeray, Flaubert, though in several cases I do not know what these people looked like and do not want to know. What one sees is the face that the writer ought to have. Well, in the case of Dickens I see a face that is not quite the face of Dickens's photographs, though it resembles it. It is the face of a man of about forty, with a small beard and a high colour. He is laughing, with a touch of anger in his laughter, but no triumph, no malignity. It is the face of a man who is always fighting against something, but who fights in the open and is not frightened, the face of a man who is generously angry — in other words, of a nineteenth-century liberal, a free intelligence, a type hated with equal hatred by all the smelly little orthodoxies which are now contending for our souls.
