Famous quotes containing the word classes:
“I am ... by tradition and long study a complete snob. P. Marlowe and I do not despise the upper classes because they take baths and have money; we despise them because they are phony.”
—Raymond Chandler (1888–1959)
“The difference between people isn’t in their class, but in themselves. Only from the middle classes one gets ideas, and from the common people—life itself, warmth. You feel their hates and loves.”
—D.H. (David Herbert)
“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)
