Let us learn from the novel. In the novel, the characters can do nothing but live. If they keep on being good, according to pattern, or bad, according to pattern, or even volatile, according to pattern, they cease to live, and the novel falls dead. A character in a novel has got to live, or it is nothing.
We, likewise, in life have got to live, or we are nothing.
– D.H. Lawrence, Why the Novel Matters
