    What can you do against the lunatic who is more intelligent than yourself, who gives your arguments a fair hearing and then simply persists in his lunacy.

    I guess the definition of a lunatic is a man surrounded by them.
    Ezra Pound (1885–1972)

    A lunatic may be “soothed,”... for a time, but in the end, he is very apt to become obstreperous. His cunning, too, is proverbial, and great.... When a madman appears thoroughly sane, indeed, it is high time to put him in a straight jacket.
