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)
“So that with much ado I was corrupted, and made to learn the dirty devices of this world.
Which now I unlearn, and become, as it were, a little child again that I may enter into the Kingdom of God.”
—Thomas Traherne (1636–1674)
