"One of our greatest judges, Learned Hand, explained: "Liberty lies in the hearts of men and women. When it dies there, no constitution, no law, no court can save it" But our understanding today must go beyond the recognition that ‘liberty lies in (our) hearts’ to the further recognition that only citizens with knowledge about the content and meaning of our constitutional guarantees of liberty are likely to cherish those concepts." U.S. Supreme Court Justice Sandra Day O’Connor Philadelphia Liberty Medal acceptance speech, July 4, 2003
