comes from an instinct so profound and absorbing that it carries a train
of evils in its wake. Many are overweighted by the sex instinct to their
positive harm. Nature somehow did not trust such a fundamental duty as
the preservation of the race to reason. If intellectual processes were
responsible for life, the world no doubt would soon be bare of animate
things. Neither could the care of the young be trusted to anything but
the deep-seated instinct that causes the mother to forget her own life
in the preservation of the life of her child.

The functions of body, on which life is founded, do not depend upon
reason. The heart begins to beat before birth; it continues to beat
until the end of life. The reason has nothing to do with the heart
performing its function. Man goes to sleep at night confident that it
will still be beating in the morning. The blood circulates in the veins
independent of the thoughts of man. The digestive processes go on
whether he sleeps or is awake. Many of his muscles never rest from birth
to death. Life could not be preserved through the intellectual
processes.

Human action is governed largely by instinct and emotion. These
instincts and emotions are incident to every living machine and are the
motor forces that impel the organism. They do not think. They act, and
act at once. All the mind can do is to place some restraint on such
instincts and emotions through experience, education and settled habits.
If the actions are never inhibited, the machine will tear itself to
pieces. If too easily inhibited, it will do no work. It is manifest that
the perfect machine does not exist.

Man is moved by his instinct of flight and his emotion of fear, which
are set in motion by apprehended dangers and by unaccustomed sights or
