Famous quotes containing the words direct and/or measuring:
“The charms of the passing woman are generally in direct proportion to the swiftness of her passing.”
—Marcel Proust (1871–1922)
“As an example of just how useless these philosophers are for any practice in life there is Socrates himself, the one and only wise man, according to the Delphic Oracle. Whenever he tried to do anything in public he had to break off amid general laughter. While he was philosophizing about clouds and ideas, measuring a flea’s foot and marveling at a midge’s humming, he learned nothing about the affairs of ordinary life.”
—Desiderius Erasmus (c. 1466–1536)
