Famous quotes containing the word science:
“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)
“Art is the beautiful way of doing things. Science is the effective way of doing things. Business is the economic way of doing things.”
—Elbert Hubbard (1856–1915)
