persons is enormous. 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 aeroplane, as our grandfathers took
for granted the miracles of the gospels. He neither questions nor
understands them. It is as though each of us investigated and made his
own only 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 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 Jowett, 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 realised at the age of
seventy that he still knew nothing.
