“I wonder if you've ever considered how strange it is that the educational and character-shaping structures of our culture expose us but a single time in our lives to the ideas of Socrates, Plato, Euclid, Aristotle, Herodotus, Augustine, Machiavelli, Shakespeare, Descartes, Rousseau, Newton, Racine, Darwin, Kant, Kierkegaard, Tolstoy, Schopenhauer, Goethe, Freud, Marx, Einstein, and dozens of others of the same rank, but expose us annually, monthly, weekly, and even daily to the ideas of persons like Jesus, Moses, Muhammad, and Buddha. Why is it, do you think, that we need quarterly lectures on charity, while a single lecture on the laws of thermodynamics is presumed to last us a lifetime? Why is the meaning of Christmas judged to be so difficult of comprehension that we must hear a dozen explications of it, not once in a lifetime, but every single year, year after year after year?”
