Nature has many scenes to exhibit, and constantly draws a curtain over this part or that. She is constantly repainting the landscape and all surfaces, dressing up some scene for our entertainment. Lately we had a leafy wilderness; now bare twigs begin to prevail, and soon she will surprise us with a mantle of snow. Some green she thinks so good for our eyes that, like blue, she never banishes it entirely from our eyes, but has created evergreens.
Henry David ThoreauIn my short experience of human life, the outward obstacles, if there were any such, have not been living men, but the institutions of the dead.
Henry David Thoreau
