Emerson was under no illusion as to the effect of distance. He knew the past was once the present, and that if it seemed to be transformed and to rise into cloud-land behind us, it was only the enchantment of distance--an enchantment which men have been under in all ages. The everyday, the near-at-hand, become prosaic; there is no room for the alchemy of time and space to work in. It has been said that all martyrdoms looked mean in the suffering. Holy ground is not holy when we walk upon it. The now and the here seem cheap and commonplace. Emerson knew that "a score of airy miles will smooth rough Monadnoc to a gem," but he knew also that it would not change the character of Monadnoc. He knew that the past and the present, the near and the far, were made of one stuff. He united the courage of science with the sensibility of poetry. He would not be defrauded of the value of the present hour, or of the thoughts which he and other men think, or of the lives which they live to-day. "I will tell you how you can enrich me--if you will recommend to-day to me." His doctrine of self-reliance, which he preached in season and out of season, was based upon the conviction that Nature and the soul do not become old and outworn, that the great characters and great thoughts of the past were the achievements of men who trusted themselves before custom or law. The sun shines to-day; the constellations hang there in the heavens the same as of old. God is as near us as ever He was--why should we take our revelations at second hand? No other writer who has used the English language has ever preached such a heroic doctrine of self-trust, or set the present moment so high in the circle of the years, in the diadem of the days.
