Doubt

I remember Father Thomas Cassady, the rector of my seminary, Sacred Heart School of Theology in Hales Corners, Wisconsin, once saying that all of us doubt, if even for a moment.  I was reminded of his quote when I saw this quote from French philosopher, mathematician, and scientist René Descartes  (1596 - 1650): If you would be a real seeker after truth, it is necessary that at least once in your life you doubt, as far as possible, all things.
