Famous quotes containing the word economy:
“It enhances our sense of the grand security and serenity of nature to observe the still undisturbed economy and content of the fishes of this century, their happiness a regular fruit of the summer.”
—Henry David Thoreau (1817–1862)
“Quidquid luce fuit tenebris agit: but also the other way around. What we experience in dreams, so long as we experience it frequently, is in the end just as much a part of the total economy of our soul as anything we “really” experience: because of it we are richer or poorer, are sensitive to one need more or less, and are eventually guided a little by our dream-habits in broad daylight and even in the most cheerful moments occupying our waking spirit.”
—Friedrich Nietzsche (1844–1900)
