Henry David Thoreau (1817-1862), A Week on the Concord and Merrimack Rivers
It would be worth the while to select our reading, for books are the society we keep; to read only the serenely true; never statistics, nor fiction, nor news, nor reports, nor periodicals, but only great poems, and when they failed, read them again, or perchance write more. Instead of other sacrifice, we might offer up our perfect (τελεία) thoughts to the gods daily, in hymns or psalms. For we should be at the helm at least once a day. The whole of the day should not be daytime; there should be one hour, if no more, which the day did not bring forth. Scholars are wont to sell their birthright for a mess of learning. But is it necessary to know what the speculator prints, or the thoughtless study, or the idle read, the literature of the Russians and the Chinese, or even French philosophy and much of German criticism? Read the best books first, or you may not have a chance to read them at all. "There are the worshipers with offerings, and the worshipers with mortifications; and again the worshipers with enthusiastic devotion; so there are those the wisdom of whose reading is their worship, men of subdued passions and severe manners;—This world is not for him who doth not worship; and where, O Arjoon, is there another?" Certainly, we do not need to be soothed and entertained always like children. He who resorts to the easy novel, because he is languid, does no better than if he took a nap. The front aspect of great thoughts can only be enjoyed by those who stand on the side whence they arrive. Books, not which afford us a cowering enjoyment, but in which each thought is of unusual daring; such as an idle man cannot read, and a timid one would not be entertained by, which even make us dangerous to existing institutions,—such call I good books.
All that are printed and bound are not books; they do not necessarily belong to letters, but are oftener to be ranked with the other luxuries and appendages of civilized life. Base wares are palmed off under a thousand disguises.
