Famous quotes containing the words strong and/or property:
“The fate of the country does not depend on how you vote at the polls,—the worst man is as strong as the best at that game; it does not depend on what kind of paper you drop into the ballot- box once a year, but on what kind of a man you drop from your chamber into the street every morning.”

Can come upon the visage of the moon
When it has looked in glory from a cloud.”
—William Butler Yeats (1865–1939)
