Famous quotes containing the word basis:
“The basis of political economy is non-interference. The only safe rule is found in the self-adjusting meter of demand and supply. Do not legislate. Meddle, and you snap the sinews with your sumptuary laws.”
—Ralph Waldo Emerson (1803–1882)
“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)
