I have tried to show in a previous chapter that 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.
