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 implanted in his imagination, no matter how utterly his reason may reject them. – Oliver Wendell Holmes, Sr., The Poet at the Breakfast Table, 1872

More persons, on the whole, are humbugged by believing in nothing than by believing in too much. – P. T. (Phineas Taylor) Barnum

This is how humans are: we question all our beliefs, except for the ones we really believe, and those we never think to question. – Orson Scott Card

Some things have to be believed to be seen. – Ralph Hodgson, The Skylark and Other Poems
