opic method of Gall and Spurzheim, in which I found no
difficulty in detecting the errors of my predecessors, and discovering
the truths which are so patent to one who seeks them. But alas, the
dispassionate search for truth is the rarest virtue on earth. Even
Gall himself had not enough of this to recognize the discoveries of
Spurzheim. Nor had Spurzheim enough to get rid of some of the palpable
errors of Gall, such as placing Acquisitiveness in the temples,
Mirthfulness in the philosophic group, and reversing the true
positions of Tune and Constructiveness, extending the latter into the
middle lobe. Spurzheim, however, was a better and more faithful
observer than Gall, and greatly improved the science of Phrenology,
though he never realized that from the brain we may develop a complete
Anthropology.

This hasty enumeration of the psychic portion of the demonstrated
functions of the brain, which my predecessors failed to reach, will
give the reader some idea of the magnitude of the task to discover all
this, to establish its relations to anatomy, and, I may add, to
cerebral mathematics, and to organize the whole into a harmonious
philosophy, which demonstrates itself, when understood, by a divine
perfection which is beyond the power of human invention to originate.

Perhaps some readers may feel that I should have introduced the
subject by systematic demonstrations and narratives of experiments. I
avoid this because such narratives would not be attractive to readers
who are eager to reach a valuable truth, and do not wish to go through
the labors of discovery. Nor am I at all concerned about
demonstrations. If I have unveiled eternal truths, my successors, if
they are faithful students, will be compelled to see what I have seen,
and to verify my observations.

I simply KNOW the truth of what I present, from several reasons, each
one of which is sufficient in itself.

1. EXPERIMENTAL.--As an experimental investigation I have many
thousand times excited the organs of the brain in intelligent persons
and made them realize or show the effects as I stimulated the
intellect, the emotions, the passions or the physiological functions,
so as to bring out Memory, Intuition, Somnolence, Spirituality, Love,
Religion, Hope to ecstasy, Pride, Arrogance, Combativeness, Avarice,
Hunger, Theft, Insanity, Sleep, Mirth, Grief, etc., etc., and the
organs that change the action of the heart, the muscular strength and
the bodily temper
