For this feeling there are many apologies, for there was never yet an error, however flagrant and hurtful, for which some plausible defense could not be framed... The two best arguments in the defense are, first, the worthlessness of the class against which it is directed; and, second, that the feeling itself is entirely natural. The way to overcome the first argument is to work for the elevation of those deemed worthless, and thus make them worthy of regard, and they will soon become worthy and not worthless. As to the natural argument, it may be said that nature has many sides. Many things are in a certain sense natural, which are neither wise nor best. It is natural to walk, but shall men therefore refuse to ride? It is natural to ride on horseback, shall men therefore refuse steam and rail?
