Famous quotes containing the words crystal and/or habit:
“Wise men read very sharply all your private history in your look and gait and behavior. The whole economy of nature is bent on expression. The tell-tale body is all tongues. Men are like Geneva watches with crystal faces which expose the whole movement.”
—Ralph Waldo Emerson (1803–1882)
“The reverence for the deeds of our ancestors is a treacherous sentiment. Their merit was not to reverence the old, but to honor the present moment; and we falsely make them excuses of the very habit which they hated and defied.”
—Ralph Waldo Emerson (1803–1882)
