Famous quotes containing the word design:
“Westerners inherit
A design for living
Deeper into matter—
Not without due patter
Of a great misgiving.”

“Humility is often only the putting on of a submissiveness by which men hope to bring other people to submit to them; it is a more calculated sort of pride, which debases itself with a design of being exalted; and though this vice transform itself into a thousand several shapes, yet the disguise is never more effectual nor more capable of deceiving the world than when concealed under a form of humility.”
—François, Duc De La Rochefoucauld (1613–1680)
“You can make as good a design out of an American turkey as a Japanese out of his native stork.”
