The real searcher after truth will not receive the old because it is old, or reject the new because it is new. He will not believe men because they are dead, or contradict them because they are alive. With him an utterance is worth the truth, the reason it contains, without the slightest regard to the author. He may have been a king or serf - a philosopher or servant, - but the utterance neither gains nor loses in truth or reason. Its value is absolutely independent of the fame or station of the man who gave it to the world.
