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 ThoreauFirst, there is the power of the Wind, constantly exerted over the globe... Here is an almost incalculable power at our disposal, yet how trifling the use we make of it.
