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 ThoreauHow insupportable would be the days, if the night with its dews and darkness did not come to restore the drooping world. As the shades begin to gather around us, our primeval instincts are aroused, and we steal forth from our lairs, like the inhabitants of the jungle, in search of those silent and brooding thoughts which are the natural prey of the intellect.
Henry David ThoreauI do not know how to distinguish between waking life and a dream. Are we not always living the life that we imagine we are?
Henry David Thoreau
