Seen from the nook and chimney-side of prudence, it wears a ragged and dangerous front. The violations of the laws of nature by our predecessors and our contemporaries are punished in us also. The disease and deformity around us certify the infraction of natural, intellectual, and moral laws, and often violation on violation to breed such compound misery. A lockjaw that bends a man's head back to his heels, hydrophobia that makes him bark at his wife and babes, insanity that makes him eat grass; war, plague, cholera, famine indicate a certain ferocity in nature, which, as it had its inlet by human crime, must have its outlet by human suffering. Unhappily, almost no man exists who has not in his own person become, to some amount, a stockholder in the sin, and so made himself liable to a share in the expiation.
