"People are sometimes inclined to think that after all it does not so very much matter if a man’s ideas about death are distorted; when he dies, they say, he will find out the facts for himself, and if he has been mistaken he will soon realize it. Such a contention is defective in two ways; (it takes no account of the awful terror of death which from ignorance overshadows the lives of so many, nor of all the unnecessary sorrow and anxiety felt by the survivors about the fate of departed friends; and it ignores the fact that man after death very often does not immediately realize his mistakes, and correct them by the light of the truth—and that in consequence of his inability to do this, much trouble frequently arises."
