A thought, even a possibility, can shatter and transform us.
Friedrich Wilhelm Nietzsche

Every now and then a man's mind is stretched by a new idea or sensation, and never shrinks back to its former dimensions.
Oliver Wendell Holmes Sr., Autocrat of the Breakfast Table

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 cliches of our forebears. We subject all facts to a prefabricated set of interpretations. We enjoy the comfort of opinion without the discomfort of thought.
