Famous quotes containing the word eccentricity:
“Eccentricity has always abounded when and where strength of character has abounded; and the amount of eccentricity in a society has generally been proportional to the amount of genius, mental vigour, and moral courage which it contained.”
—John Stuart Mill (1806–1873)
