“All that is told of the sea has a fabulous sound to an inhabitant of the land, and all its products have a certain fabulous quality, as if they belonged to another planet, from seaweed to a sailor’s yarn, or a fish story. In this element the animal and vegetable kingdoms meet and are strangely mingled.”
—Henry David Thoreau (1817–1862)
“Only by the supernatural is a man strong; nothing is so weak as an egotist. Nothing is mightier than we, when we are vehicles of a truth before which the state and the individual are alike ephemeral.”
—Ralph Waldo Emerson (1803–1882)
