Famous quotes containing the word convention:
“No convention gets to be a convention at all except by grace of a lot of clever and powerful people first inventing it, and then imposing it on others. You can be pretty sure, if you are strictly conventional, that you are following genius—a long way off. And unless you are a genius yourself, that is a good thing to do.”
—Katharine Fullerton Gerould (1879–1944)
“The metaphor of the king as the shepherd of his people goes back to ancient Egypt. Perhaps the use of this particular convention is due to the fact that, being stupid, affectionate, gregarious, and easily stampeded, the societies formed by sheep are most like human ones.”
—Northrop Frye (b. 1912)
