The possibility of pain is inherent in the very existence of a world where souls can meet. When souls become wicked they will certainly use this possibility to hurt one another; and this, perhaps, accounts for four-fifths of the sufferings of men. It is men, not God, who have produced racks, whips, prisons, slavery, guns, bayonets, and bombs; it is by human avarice or human stupidity, not by the churlishness of nature, that we have poverty and overwork. But there remains, nonetheless, much suffering which cannot be traced to ourselves. Even if all suffering were man-made, we should like to know the reason for the enormous permission to torture their fellows which God gives to the worst of men.
