Some Effects upon Industry.--These factors in organic evolution express
themselves more or less in the industrial phase of human society. Thus,
the first factor, the multiplication of organisms through reproduction
in some geometric ratio, was first studied by Malthus, an economist in
the beginning of the nineteenth century, and exclusively with reference
to its effect upon economic conditions. Malthus perceived the tendency
for human beings to multiply in some geometric ratio where food supply
was sufficiently abundant, and argued from this that if better wages,
and so a larger food supply, were given the lower classes, they would
multiply so much more rapidly that worse poverty would result than
before. There is no doubt that in certain classes of human society there
is a tendency for population to press against food supply, and it is in
these classes that the struggle for existence takes on its most
animal-like forms.

Again, the struggle for existence is continually illustrated in the
world of human industry. Not only do individuals lose place and power
because they are unadapted to their environment, but also economic
groups, such as corporations, show the natural competition or struggle
for existence sometimes in its most intense form. The result in all
cases is the dying out of the least adapted and the survival of the
better adapted. Thus, through competition and the survival of the better
adapted we secure in industry the evolution of higher types of
industrial organization, industrial methods, and the like, just as
higher types are secured in the same way in the animal world. Again, in
economic matters, as in other social affairs, coöperation continually
comes in to modify competition and to lift it to a higher plane. Just as
the higher type of societies has been characterized by higher types of
coöperation, so it is safe to say that the higher types of industry are
characterized by higher types of coöperation. And while, as we shall see
