at the world through his own eyes is very likely to become a dangerous
madman if he takes to looking at the world through telescopes and
microscopes. Even when he is telling fairy stories about giants and
dwarfs, the giants had better not be too big nor the dwarfs too small
and too malicious. Before the microscope came, our fairy stories only

grown-up persons at all. But the microscope men terrified themselves and
everyone else out of their wits with the invisible monsters they saw:
poor harmless little things that die at the touch of a ray of sunshine,
and are themselves the victims of all the diseases they are supposed to
produce! Whatever the scientific people may say, imagination without
microscopes was kindly and often courageous, because it worked on things
of which it had some real knowledge. But imagination with microscopes,
working on a terrifying spectacle of millions of grotesque creatures
of whose nature it had no knowledge, became a cruel, terror-stricken,
persecuting delirium. Are you aware, madam, that a general massacre
of men of science took place in the twenty-first century of the
pseudo-Christian era, when all their laboratories were demolished, and
all their apparatus destroyed?

ZOO. Yes: the shortlived are as savage in their advances as in their
relapses. But when Science crept back, it had been taught its place. The
mere collectors of anatomical or chemical facts were not supposed to
know more about Science than the collector of used postage stamps about
international trade or literature. The scientific terrorist who was
afraid to use a spoon or a tumbler until he had dipt it in some
poisonous acid to kill the microbes, was no longer given titles,
pensions, and monstrous powers over the bodies of other people: he was
sent to an asylum, and treated there until his recovery. But all that is
an old story: the extension of life to three hundred years has provided
