"An eminent physician in Holland, entrusted at once with a medical chair in the university of Leyden, and with the health of the Prince of Orange, being asked what the soul was? paused, and then answer, 'C'est un ressort. It is a spring.' As the main-spring actuates the wheels and other component part of a watch, so the soul actuates the faculties of the mind; and as the main-spring of a watch may either be broken alltogether, or hurt in different degrees, we may justly talk from analogy in the same terms of the soul."
