Famous quotes containing the word grades:
“Kindliness seems to exist primarily as an animal instinct, so deeply rooted that mental degeneracy, which works from the top down, does not destroy it until the mind sinks to the lower grades of idiocy.”
—Charles Horton Cooley (1864–1929)
“He suggested that there might be men of genius in the lowest grades of life, however permanently humble and illiterate, who take their own view always, or do not pretend to see at all; who are as bottomless even as Walden Pond was thought to be, though they may be dark and muddy.”
—Henry David Thoreau (1817–1862)
“There are no grades of vanity, there are only grades of ability in concealing it.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
