Famous quotes containing the words physical and/or properties:
“Public Opinion ... an attempt to organise the ignorance of the community, and to elevate it to the dignity of physical force.”
—Oscar Wilde (1854–1900)
“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)
