### Famous quotes containing the word basis:

Our fathers and grandfathers who poured over the Midwest were self-reliant, rugged, God-fearing people of indomitable courage.... They asked only for freedom of opportunity and equal chance. In these conceptions lies the real basis of American democracy. They and their fathers give a genius to American institutions that distinguished our people from any other in the world.
Herbert Hoover (1874–1964)

The basis of good manners is self-reliance. Necessity is the law of all who are not self-possessed.
Ralph Waldo Emerson (1803–1882)

Even upon such a basis hast thou built
A monument, whose cement hath been guilt!
George Gordon Noel Byron (1788–1824)
