The knowledge of an unlearned man is living and luxuriant like a forest, but covered with mosses and lichens and for the most part inaccessible and going to waste; the knowledge of the man of science is like timber collected in yards for public works, which still supports a green sprout here and there, but even this is liable to dry rot.
Henry David ThoreauHave you not budged an inch, then? Such is the daily news. Its facts appear to float in the atmosphere.... We should wash ourselves clean of such news. Of what consequence, though our planet explode, if there is no character involved in the explosion? In health we have not the least curiosity about such events. We do not live for idle amusement. I would not run round a corner to see the world blow up.
Henry David ThoreauIf we will admit time into our thoughts at all, the mythologies, those vestiges of ancient poems, wrecks of poems, so to speak, the world's inheritance,... these are the materials and hints for a history of the rise and progress of the race; how, from the condition of ants, it arrived at the condition of men, and arts were gradually invented. Let a thousand surmises shed some light on this story.
Henry David ThoreauDuty is one and invariable; it requires no impossibilities, nor can it ever be disregarded with impunity.
