Famous quotes containing the word invention:
““Art” is an invention of aesthetics, which in turn is an invention of philosophers.... What we call art is a game.”
—Octavio Paz (b. 1914)
“Justice is a moral virtue, merely because it has that tendency to the good of mankind, and indeed is nothing but an artificial invention to that purpose. The same may be said of allegiance, of the laws of nations, of modesty, and of good manners. All these are mere human contrivances for the interest of society.”
—David Hume (1711–1776)
“The public values the invention more than the inventor does. The inventor knows there is much more and better where this came from.”
—Ralph Waldo Emerson (1803–1882)
