Famous quotes containing the word inventions:
“The treasury of America lies in those ambitions and those energies that cannot be restricted to a special, favored class. It depends upon the inventions of unknown men; upon the originations of unknown men, upon the ambitions of unknown men. Every country is renewed out of the ranks of the unknown, not out of the ranks of those already famous and powerful and in control.”
—Woodrow Wilson (1856–1924)
