Fear paralyzes the brain. Progress is born of courage. Fear believes—courage doubts. Fear falls upon the earth and prays—courage stands erect and thinks. Fear retreats—courage advances. Fear is barbarism—courage is civilization. Fear believes in witchcraft, in devils and in ghosts. Fear is religion—courage is science.
There are real crimes enough without creating artificial ones. All progress in legislation has for centuries consisted in repealing the laws of the ghosts.
—Robert Ingersoll.
