Never quite free (Mencken)

If, as the Army tests of conscripts showed, nearly 50 per cent. of American adult males never get beyond the mental development of a twelve-year-old child, then it must be obvious that a much smaller number get beyond the mental development of a youth at the end of his teens. I put that number, at a venture, at 10 per cent. The remaining 90 per cent. never quite free themselves from religious superstitions. They may no longer believe it is an act of God every time an individual catches a cold, or sprains his ankle, or cuts himself shaving, but they are pretty sure to see some trace of divine intervention in it if he is struck by lightning, or hanged, or afflicted with leprosy or syphilis.
