One of the marks of true genius is a quality of abundance. A rich, rollicking abundance, enough to give indigestion to ordinary people. Great artists turn it out in rolls, in swatches. They cover whole ceilings with paintings, they chip out a mountainside in stone, they write not one novel but a shelf full. It follows that some of their work is better than other. As much as a third of it may be pretty bad. Shall we say this unevenness is the mark of their humanity - of their proud mortality as well as of their immortality?

A woman's biography - with about eight famous historical exceptions - so often turns out to be the story of a man and the woman who helped his career.

In writing biography, fact and fiction shouldn't be mixed. And if they are, the fictional points should be printed in red ink, the facts printed in black ink.

Chamber music - a conversation between friends.

If art has a purpose, it is to interpret life, reproduce it in fresh visions.

Writers seldom choose as friends those self-contained characters who are never in trouble, never unhappy or ill, never make mistakes, and always count their change when it is handed to them.

History is, in its essence, exciting; to present it as dull is, to my mind, stark and unforgivable misrepresentation.
