“Be not anxious to avoid poverty. In this way the wealth of the universe may be securely invested.”
—Henry David Thoreau (1817–1862)
“Philosophically considered, the universe is composed of Nature and the Soul.”

“Moreover, the universe as a whole is infinite, for whatever is limited has an outermost edge to limit it, and such an edge is defined by something beyond. Since the universe has no edge, it has no limit; and since it lacks a limit, it is infinite and unbounded. Moreover, the universe is infinite both in the number of its atoms and in the extent of its void.”
—Epicurus (c. 341–271 B.C.)
