Famous quotes containing the words measuring and/or devices:
“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)
“The gods being always close to men perceive those who afflict others with unjust devices and do not fear the wrath of heaven.”
—Hesiod (c. 8th century B.C.)
