"A Hypochondriack Preacher, would, I am sensible, be an anomalous character; for whatever part of his sermon should appear not quite intelligible, or at all unpleasant to his auditors, they might very fairly, though perhaps not very justly impute to the gloomy disease of his mind."
— Boswell, James (1740-1795)
(I, pp. 153-4 in SUP edition)
