        　　The average man who uses a telephone could not explain how a telephone
works. He takes for granted the telephone, the railway train, the linotype, the
airplane, as our grandfathers took for granted the miracles of the gospels. He
neither question nor understand them. It is as though each of us investigated
and made his own a tiny circle of facts. Knowledge outside the day's work is
regarded by most men as a gewgaw. Still we are constantly in reaction against
our ignorance. We rouse ourselves at intervals and speculate. We revel in
speculations about anything at all --- about life after death or about such
questions as that which is said to have puzzled
        　　Aristotle, "Why sneezing from noon to midnight was good, but from night to
noon unlucky?" One of the greatest joys known to man is to take such a flight
into ignorance in search of the knowledge. The great pleasure of ignorance is,
after all, the pleasure of asking questions. The man who has lost this pleasure
or exchanged it for the pleasure of dogma, which is the pleasure of answering,
is already beginning to stiffen. One envies so inquisitive a man as Jewell, who
sat down to the study of physiology in his sixties. Most of us have lost the
sense of our ignorance long before that age. We even become vain of our
squirrel's hoard of knowledge and regard increasing age itself as a school of
omniscience. We forget that Socrates was famed for wisdom not because he was
omniscient but because he realized at the age of seventy that he still knew
nothing.
