Insanity is often the logic of an accurate mind overtasked. Good mental machinery ought to break its own wheels and levers, if anything is thrust among them suddenly which tends to stop them or reverse their motion. A weak mind does not accumulate force enough to hurt itself; stupidity often saves a man from going mad. ~ The Autocrat of the Breakfast Table by Oliver Wendell Holmes, Sr.
Laughter and tears are meant to turn the wheels of the same machinery of sensibility; one is wind-power, and the other water-power; that is all. ~ The Autocrat of the Breakfast Table by Oliver Wendell Holmes, Sr.
