I cannot tell why people, brought up to believe the Bible in the old literal way as an infallible record and revelation, and rejecting that view later on, begin by rejecting the Old Testament, and give up the belief in a brimstone hell before they give up (if they ever do) the belief in a heaven of harps, crowns, and thrones. I cannot tell why people who will not believe in baptism on any terms believe in vaccination with the cruel fanaticism of inquisitors. I am convinced that if a dozen sceptics were to draw up in parallel columns a list of the events narrated in the gospels which they consider credible and incredible respectively, their lists would be different in several particulars. Belief is literally a matter of taste. FASHIONS OF BELIEF. Now matters of taste are mostly also matters of fashion. We are conscious of a difference between medieval fashions in belief and modern fashions. For instance, though we are more credulous than men were in the Middle Ages, and entertain such crowds of fortunetellers, magicians, miracle workers, agents of communication with the dead, discoverers of the elixir of life, transmuters of metals, and healers of all sorts, as the Middle Ages never dreamed of as possible, yet we will not take our miracles in the form that convinced the Middle Ages. Arithmetical numbers appealed to the Middle Ages just as they do to us, because they are difficult to deal with, and because the greatest masters of numbers, the Newtons and Leibnitzes, rank among the greatest men. But there are fashions in numbers too. The Middle Ages took a fancy to some familiar number like seven; and because it was an odd number, and the world was made in seven days, and there are seven stars in Charles's Wain, and for a dozen other reasons, they were ready to believe anything that had a seven or a seven times seven in it. Seven deadly sins, seven swords of sorrow in the heart of the Virgin, seven champions of Christendom, seemed obvious and reasonable things to believe in simply because they were seven. To us, on the contrary, the number seven is the stamp of superstition. We will believe in nothing less than millions. A medieval doctor gained his patient's confidence by telling him that his vitals were being devoured by seven worms. Such a diagnosis would ruin a modern physician. The modern physician tells his patient that he is ill because every drop of his blood is swarming with a million microbes; and the patient believes him abjectly and instantly. Had a bishop told William the Conqueror that the sun was seventy-seven miles distant from the earth, William would have believed him not only out of respect for the Church, but because he would have felt that seventy-seven miles was the proper distance. The Kaiser, knowing just as little about it as the Conqueror, would send that bishop to an asylum. Yet he (I presume) unhesitatingly accepts the estimate of ninety-two and nine-tenths
