John Fitzgerald Kennedy (191763)
For the great enemy of the truth is very often not the liedeliberate, contrived, and dishonestbut the mythpersistent, persuasive, and unrealistic. Too often we hold fast to the cliches of our forebears. We subject all facts to a prefabricated set of interpretations. We enjoy the comfort of opinions without the discomfort of thought.
