Famous quotes containing the word standards:
“The standards of His Majesty’s taste made all those ladies who aspired to his favour, and who were near the Statutable size, strain and swell themselves, like the frogs in the fable, to rival and bulk and dignity of the ox. Some succeeded, and others burst.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“In this nation I see tens of millions of its citizens, a substantial part of its whole population, who at this very moment are denied the greater part of what the very lowest standards of today call the necessities of life. I see one third of a nation ill-housed, ill-clad, ill-nourished. The test of our progress is not whether we add more to the abundance of those who have much, it is whether we provide enough for those who have too little.”
—Franklin D. Roosevelt (1882–1945)
“As long as our people quote English standards they dwarf their own proportions.”
—Ralph Waldo Emerson (1803–1882)
