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)

    “The latest refinements of science are linked with the cruelties of the Stone Age.”
    —Winston Churchill (1874–1965)

    “There is a chasm between knowledge and ignorance which the arches of science can never span.”
    —Henry David Thoreau (1817–1862)
