Human nature is said by many to be good; if so, where have social evils come from? For human nature is the only moral nature in that corrupting thing called "society." Every example set before the child of to-day is the fruit of human nature. It has been planted on every possible field among the snows that never melt; in temperate regions, and under the line; in crowded cities, in lonely forests; in ancient seats of civilization, in new colonies; and in all these fields it has, without once failing, brought forth a crop of sins and troubles.
