"For the great enemy of truth is very often not the lie - deliberate, contrived and dishonest, but the myth -persistent, persuasive, and unrealistic. Too often we hold fast to the clichés of our forebears. We subject all facts to a prefabricated set of interpretations. We enjoy the
comfort of opinion without the discomfort of thought."
-- John F. Kennedy. Commencement, Yale University. June 11, 1962
