James White, Sketches of the Christian life and public labors of William Miller (1875)
“ Miller, ‘I don’t know but I am a monomaniac; and I want you to examine me, and see if I am; and if so, cure me. Can you tell when a man is a monomaniac?’“The doctor blushed, and said he thought he could.“Mr. Miller wished to know how.“‘Why,’ said the doctor, ‘a monomaniac is rational on all subjects but one; and when you touch that particular subject, he will become raving.’“‘Well,’ said Mr. Miller, ‘I insist upon it that you see whether I am in reality a monomaniac; and if I am, you shall prescribe for and cure me. ”
