he magic ooze of their silent
chemistry precisely as a tree of tin crystals arises from the chemical
reactions started in a solution of tin salts by an electric current.

Man is regulated by his Glands of Internal Secretion. At the beginning
of the third decade of the twentieth century, after he had struggled,
for we know at least fifty thousand years, to define and know himself,
that summary may be accepted as the truth about himself. It is
a far-reaching induction, but a valid induction, supported by a
multitude of detailed facts.

Amazingly enough, the incontestable evidence, that first pointed to,
and then proved up to the hilt, this answer to the question: What is
Man? has been gathered in less than the last fifty years. Darwin and
Huxley, and Spencer, who first opened men's eyes to their origins,
were ignorant of the very existence of some of them, and had not the
faintest notion or suspicion of the real importance or function of any
of them.

THE PREJUDICES OF PHILOSOPHERS

Now, there are certain prejudices and problems which appear to be
rudely brushed away by the dogmatic arrogance of the principle stated.
What, you say, is Man but an affair of his peculiar gland chemistry?
But what of mind, soul, consciousness? Still another of these
pathetically one-sided and superficial theories of man as a machine
pure and simple which would make him the most complicated of
mechanisms, a marvel of intricate parts, but would deprive him of his
essence as self-conscious unique in the universe. Man, thinking man,
at any rate, dreads to lose the cherished impregnable conviction that
he is something apart, inherently, and therefore infinitely different
from every other phenomenon in the range of his cosmos.

A thorough dissection of the relation and attitude toward psychic
material of the consistent physiologist, who refuses to deal in
contradictory terms, would lead us a little too far. So would the
reconciliation between the claims of mind and the concept of the
organism as a system of chemical reactions. The most fundamental
aspects of that herculean task, warned by the sign, No Trespassing,
we shall leave to the metaphysicians. The influence of the glands of
internal secretion upon the mind we must consider, but at present
postpone. Yet the hot-headed contenders on both sides may be reminded
of certain facts.

We live in the most iconoclastic of ages. There are sane people alive
today going quietly about their busine
