Famous quotes containing the words physical and/or properties:
“Patience, that blending of moral courage with physical timidity.”
—Thomas Hardy (1840–1928)
“A drop of water has the properties of the sea, but cannot exhibit a storm. There is beauty of a concert, as well as of a flute; strength of a host, as well as of a hero.”
—Ralph Waldo Emerson (1803–1882)
