Famous quotes containing the word classes:
“Is a man too strong and fierce for society, and by temper and position a bad citizen,—a morose ruffian, with a dash of the pirate in him;Mnature sends him a troop of pretty sons and daughters, who are getting along in the dame’s classes at the village school, and love and fear for them smooths his grim scowl to courtesy. Thus she contrives to intenerate the granite and the feldspar, takes the boar out and puts the lamb in, and keeps her balance true.”
—Ralph Waldo Emerson (1803–1882)
“My plan of instruction is extremely simple and limited. They learn, on week-days, such coarse works as may fit them for servants. I allow of no writing for the poor. My object is not to make fanatics, but to train up the lower classes in habits of industry and piety.”
—Hannah More (1745–1833)
“Of all classes the rich are the most noticed and the least studied.”
—John Kenneth Galbraith (b. 1908)
