Famous quotes containing the word invention:
“For this invention of yours will produce forgetfulness in the minds of those who learn it, by causing them to neglect their memory, inasmuch as, from their confidence in writing, they will recollect by the external aid of foreign symbols, and not by the internal use of their own faculties. Your discovery, therefore, is a medicine not for memory, but for recollection,—for recalling to, not for keeping in mind.”
—Plato (c. 427–347 B.C.)
“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)
“Methinks the human method of expression by sound of tongue is very elementary, & ought to be substituted for some ingenious invention which should be able to give vent to at least six coherent sentences at once.”
—Virginia Woolf (1882–1941)
