Not A Science

Die Politik ist keine Wissenschaft, wie viele der Herren Proffessoren sich einbilden, sondern eine Kunst (Politics is not a science, as the professors are apt to suppose.  It is an art).

-- Prince Otto Eduard Leopold von Bismarck, Duke of Lauenburg (1815 - 1898), German aristocrat and statesman, expression in the Reichstag (1884), as quoted in The Quote Verifier : Who Said What, Where, and When (2006) by Ralph Keyes
