discoveries of modern science to filter down through such media as the
current periodicals to the rank and file of society. The situation seems
to illustrate the old adage that a lie will travel round the world while
truth is getting on her shoes. _Thus it happens that the common people
are still being taught in this second decade of the twentieth century
many things that real scientists outgrew nearly a generation ago, and
assertions are still being bandied around in the individual sciences
which are wholly unwarranted by a general survey of the whole field of
modern natural science_. Indeed, in almost every one of the separate
sciences the arguments upon which the theory of Evolution gained its
popularity a generation or so ago are now known by the various
specialists to have been blunders, or mistakes, or hasty conclusions of
one kind or another. Thus the market value of all the various subsidiary
stocks of the Evolution group has been steadily declining in their
respective home markets, and now stands away below par; while strange to
say the stock of the central holding company itself is still quoted at
fictitiously high figures.

This curious--not to say deplorable--situation has developed largely
because of the modern system of strict specialization in the various
departments of science. Each scientist feels compelled by an unwritten
but rigid code of professional ethics to confine himself strictly to the
cultivation of the little plot of ground on which he happens to be
working, and is forbidden to express an opinion about what he may know
has been discovered on another plot of ground on which his neighbor is
working, except by express permission. In other words, science teaching
has now become strictly a matter of authority, this authority being
vested in the various specialists; and nobody is permitted to look at it
in a broad way, or to frame a general induction from the sum of all the
facts of nature now discovered, under penalty of scientific
