Wow!  They don't write poison pen letters like that anymore.

Robert Louis Stevenson responds to the slander of Father Damien of Molokai by the Rev. Dr. Hyde of Honolulu:

AN OPEN LETTER TO THE REVEREND DR. HYDE OF HONOLULU


SYDNEY,

FEBRUARY 25, 1890.

Sir, - It may probably occur to you that we have met, and visited, and conversed; on my side, with interest. You may remember that you have done me several courtesies, for which I was prepared to be grateful. But there are duties which come before gratitude, and offences which justly divide friends, far more acquaintances. Your letter to the Reverend H. B. Gage is a document which, in my sight, if you had filled me with bread when I was starving, if you had sat up to nurse my father when he lay a-dying, would yet absolve me from the bonds of gratitude. You know enough, doubtless, of the process of canonisation to be aware that, a hundred years after the death of Damien, there will appear a man charged with the painful office of the DEVIL'S ADVOCATE. After that noble brother of mine, and of all frail clay, shall have lain a century at rest, one shall accuse, one defend him. The circumstance is unusual that the devil's advocate should be a volunteer, should be a member of a sect immediately rival, and should make haste to take upon himself his ugly office ere the bones are cold; unusual, and of a taste which I shall leave my readers free to qualify; unusual, and to me inspiring. If I have at all learned the trade of using words to convey truth and to arouse emotion, you have at last furnished me with a subject. For it is in the interest of all mankind, and the cause of public decency in every quarter of the world, not only that Damien should be righted, but that you and your letter should be displayed at length, in their true colours, to the public eye.

And the next time you think about slandering your betters, consider this bit of prophecy:

Damien has been too much depicted with a conventional halo and conventional features; so drawn by men who perhaps had not the eye to remark or the pen to express the individual; or who perhaps were only blinded and silenced by generous admiration, such as I partly envy for myself - such as you, if your soul were enlightened, would envy on your bended knees. It is the least defect of such a method of portraiture that it makes the path easy for the devil's advocate, and leaves the misuse of the slanderer a considerable field of truth. For the truth that is suppressed by friends is the readiest weapon of the enemy. The world, in your despite, may perhaps owe you something, if your letter be the means of substituting once for all a credible likeness for a wax abstraction. For, if that world at all remember you, on the day when Damien of Molokai shall be named a Saint, it will be in virtue of one work: your letter to the Reverend H. B. Gage.

As a bit of practical wisdom, and as guide on how to gracefully stick a literary knife into someone, the entire letter is worth reading.
