Prefaces are another stumbling-block. "The 'I,'" said Pascal, "is hateful." Speak as little of yourself as possible; for you must know that the reader's self-esteem is as great as yours. He will never forgive you for wanting to condemn him to have a good opinion of you. It is for your book to speak for you, if it comes to be read by the crowd.
If you want to be an author, if you want to write a book; reflect that it must be useful and new, or at least infinitely agreeable.
If an ignoramus, a pamphleteer, presumes to criticize without discrimination, you can confound him; but make rare mention of him, for fear of sullying your writings.
If you are attacked as regards your style, never reply; it is for your work alone to make answer.
Someone says you are ill, be content that you are well, without wanting to prove to the public that you are in perfect health. And above all remember that the public cares precious little whether you are well or ill.
