person to any science.

No science is independent. The science of physics, for example, could
never have reached its present-day state of development if it had not laid
heavy tribute upon the sciences of mathematics, astronomy, chemistry,
geography, mechanics, optics, and others. In a similar way, the science of
character analysis has derived many of its facts, laws, and even
principles, from the sciences of physics, chemistry, biology,
anthropology, ethnology, geography, geology, anatomy, physiology,
histology, embryology, psychology, and others. Since this is true, it is
obvious that the work of collecting, verifying, classifying, analyzing,
and organizing the facts upon which the science of character analysis is
based has been going on from the very dawn of civilization. Many
investigators, students and scholars, in many branches of knowledge, have
labored, added their little mite to the sum total, and passed on. The net
result of all their work, all their thousands of years of research,
investigation, study and thought, can now be gathered together and
presented in so simple a form that it can be learned by anyone of
intelligence in a few months. It took humanity untold thousands of years
to learn the scientific truth that the earth is an oblate spheroid. Many
men gave their lives to establish the truth. As a result, to-day every
schoolboy learns and understands the fact within a very few days after his
first opening of a text book on geography. Thousands of scholars have been
working on the science of physics from the dawn of human intelligence down
to the present date. Now a high school student learns all of its
essentials and fundamentals in a short term of fourteen weeks.

A SHORT CUT TO KNOWLEDGE

The second method of learning a science, therefore, is to take advantage
of all that has been done and, instead of beginning with facts and working
up to principles, begin with principles and work down to a practical
application amongst facts.

There are many ways of learning principles. One may memorize them from
books, or have them set forth and explained by an instructor or lecturer,
or stumble upon them in general reading, or work out a series of carefully
prescribed experiments in a laboratory, leading up to an enunciation of
the principles or, through its intelligent application in the world of
work, establish it in one's consciousness.

The student who learns his laws and principles out of books may have
