“Here commences what was called, twenty years ago, the best timber land in the State. This very spot was described as “covered with the greatest abundance of pine,” but now this appeared to me, comparatively, an uncommon tree there,—and yet you did not see where any more could have stood, amid the dense growth of cedar, fir, etc.”
—Henry David Thoreau (1817–1862)

“The struggle for existence holds as much in the intellectual as in the physical world. A theory is a species of thinking, and its right to exist is coextensive with its power of resisting extinction by its rivals.”
—Thomas Henry Huxley (1825–95)
