Famous quotes containing the words natural and/or son:
““What we know, is a point to what we do not know.” Open any recent journal of science, and weigh the problems suggested concerning Light, Heat, Electricity, Magnetism, Physiology, Geology, and judge whether the interest of natural science is likely to be soon exhausted.”
—Ralph Waldo Emerson (1803–1882)
“He certainly must be a son of Aurora to whom the sun looms, when there are so many millions to whom it glooms rather, or who will never see it till an hour after it has risen. But it behooves us old stagers to keep our lamps trimmed and burning to the last, and not trust to the sun’s looming.”
—Henry David Thoreau (1817–1862)
