The indescribable innocence and beneficence of Nature-of sun and wind and rain, of summer and winter-such health, such cheer, they afford forever! and such sympathy have they ever with our race, that all Nature would be affected, and the sun's brightness fade, and the winds would sigh humanely, and the clouds rain tears, and the woods shed their leaves and put on mourning in midsummer, if any man should ever for a just cause grieve. - Henry David Thoreau
