Famous quotes containing the word science:
“He is not a true man of science who does not bring some sympathy to his studies, and expect to learn something by behavior as well as by application. It is childish to rest in the discovery of mere coincidences, or of partial and extraneous laws. The study of geometry is a petty and idle exercise of the mind, if it is applied to no larger system than the starry one.”
—Henry David Thoreau (1817–1862)
“If you have science and art,
You also have religion;
But if you don’t have them,
You better have religion.”
—Johann Wolfgang Von Goethe (1749–1832)
