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 ThoreauDo not be too moral. You may cheat yourself out of much life so. Aim above morality. Be not simply good; be good for something.
Henry David ThoreauAh! I need solitude. I have come forth to this hill at sunset to see the forms of the mountains in the horizon - to behold and commune with something grander than man. Their mere distance and unprofanedness is an infinite encouragement. it is with infinite yearning and aspiration that I seek solitude, more and more resolved and strong; but with a certain weakness that I seek society ever.
Henry David Thoreau
