Every man is a missionary, now and forever, for good or for evil, whether he intends or designs it or not. He may be a blot radiating his dark influence outward to the very circumference of society, or he may be a blessing spreading benediction over the length and breadth of the world. But a blank he cannot be: there are no moral blanks; there are no neutral characters.
