We are all tattooed in our cradles with the beliefs of our tribe; the record may seem superficial, but it is indelible. You cannot educate a man wholly out of the superstitious fears which were early implanted in his imagination; no matter how utterly his reason may reject them, he will still feel as the famous woman did about ghosts, Je ne crois pas, mais je les crains, — “I don’t believe in them, but I am afraid of them, nevertheless.”

Oliver Wendell Holmes, Sr. (1809-1894) American poet, essayist, scholar
