Famous quotes containing the word science:
“There are some things in science which should be brought to light. There are others, doctor, which should be left alone.”
—Griffin Jay, Maxwell Shane (1905–1983)
“There are two kinds of truth; the truth that lights the way and the truth that warms the heart. The first of these is science, and the second is art.... Without art science would be as useless as a pair of high forceps in the hands of a plumber. Without science art would become a crude mess of folklore and emotional quackery.”
—Raymond Chandler (1888–1959)
