I never found the companion that was so companionable as solitude. [It allows you to] be the Mungo Park, the Lewis and Clark of your own streams and oceans; [to] explore your own higher latitudes; [to] be a Columbus to whole new continents and worlds within you, opening new channels, not of trade, but of thought.
Henry David ThoreauNo method nor discipline can supersede the necessity of being forever on the alert. What is a course of history, or philosophy, or poetry, or the most admirable routine of life, compared with the discipline of looking always at what is to be seen? Will you be a reader, a student merely, or a seer?
Henry David ThoreauCritical acumen is exerted in vain to uncover the past; the past cannot be presented; we cannot know what we are not. But one veilhangs over past, present, and future, and it is the province of the historian to find out, not what was, but what is. Where a battle has been fought, you will find nothing but the bones of men and beasts; where a battle is being fought, there are hearts beating.
Henry David ThoreauLiterary gentlemen, editors, and critics think that they know how to write, because they have studied grammar and rhetoric; but they are egregiously mistaken. The art of composition is as simple as the discharge of a bullet from a rifle, and its masterpieces imply an infinitely greater force behind them.
