Any mother or father knows that no child has to be taught to be selfish or envious or unkind. These natural traits manifest themselves before the child is out of diapers and long before society has had any influence upon him. The restraint of discipline in the home (little known these days), the restraint of the conscience which God has placed within us all, the restraint of knowing that others would disapprove, and the restraint of teachers, friends, and government all work to keep outward evil somewhat in check.
There is no restraint, however, upon imagination except conscience. There self reigns and fantasies may be enjoyed that one would be ashamed of in the real world. In the imagination one can indulge the basest passions—and the world of the occult can be easily entered.
