I have heard of a man lost in the woods and dying of famine and exhaustion at the foot of a tree, whose loneliness was relieved by the grotesque visions with which, owing to bodily weakness, his diseased imagination surrounded him, and which he believed to be real. So also, owing to bodily and mental health and strength, we may be continually cheered by a like but more normal and natural society, and come to know that we are never alone.
Henry David ThoreauDid you ever hear of a man who had striven all his life faithfully and singly towards an object, and in no measure obtained it? If a man constantly aspires, is he not elevated? Did ever a man try heroism, magnanimity, truth, sincerity, and find that there was no advantage in them,--that it was a vain endeavor?
Henry David Thoreau
