hidden fear, a nervous trembling, a sense of insecurity. And this
is due to their upbringing. They know that the sages, statesmen
and artists whom today they revere, were yesterday spurned as
swindlers and charlatans. And the higher the segment in the
triangle, the better defined is this fear, this modern sense of
insecurity. Here and there are people with eyes which can see,
minds which can correlate. They say to themselves: "If the
science of the day before yesterday is rejected by the people of
yesterday, and that of yesterday by us of today, is it not
possible that what we call science now will be rejected by the
men of tomorrow?" And the bravest of them answer, "It is
possible."

Then people appear who can distinguish those problems that the
science of today has not yet explained. And they ask themselves:
"Will science, if it continues on the road it has followed for so
long, ever attain to the solution of these problems? And if it
does so attain, will men be able to rely on its solution?" In
these segments are also professional men of learning who can
remember the time when facts now recognized by the Academies as
firmly established, were scorned by those same Academies. There
are also philosophers of aesthetic who write profound books about
an art which was yesterday condemned as nonsense. In writing
these books they remove the barriers over which art has most
recently stepped and set up new ones which are to remain for ever
in the places they have chosen. They do not notice that they are
busy erecting barriers, not in front of art, but behind it. And
if they do notice this, on the morrow they merely write fresh
books and hastily set their barriers a little further on. This
performance will go on unaltered until it is realized that the
