The wisest man preaches no doctrines; he has no scheme; he sees no rafter, not even a cobweb, against the heavens. It is clear sky.
Henry David ThoreauIt is the characteristic of great poems that they will yield of their sense in due proportion to the hasty and the deliberate reader. To the practical they will be common sense, and to the wise wisdom; as either the traveler may wet his lips, or an army may fill its water-casks at a full stream.
Henry David Thoreau
