Charles H. Spurgeon on Psalms 92:6

A fool. The simpleton is an automaton, he is a machine, he is worked by a spring; mere gravity carries him forward, makes him move, makes him turn, and that unceasingly and in the same way, and exactly with the same equable pace: he is uniform, he is never inconsistent with himself; whoever has seen him once, has seen him at all moments, and in all periods of his life; he is like the ox that bellows, or the blackbird which whistles; that which is least visible in him is his soul; it does not act, it is not exercised, it takes its rest. —Jean de la Bruyère (1639-1696), quoted by Ramage.
