arge extent determines its own destinies, establishes its own rules of
education and conduct, and thus influences every step we are free to take
within the structure of our social system. But the power of human beings
to determine their own destinies is limited by natural law, Nature's law.
It is the counsel of wisdom to discover the laws of nature, including the
laws of human nature, and then to live in accordance with them. The
opposite is folly.

A farmer must know the natural laws that govern his wheat, or corn, or
cow, as otherwise he will not have satisfactory crops, or the quality and
abundance of milk he desires, whereas the knowledge of these laws enables
him to produce the most favorable conditions for his plants and animals,
and thereby to gain the desired results.

Humanity must know the natural laws for humans, otherwise humans will not
create the conditions and the customs that regulate human activities which
will make it possible for them to have the most favorable circumstances
for the fullest human development in life; which means the release of the
maximum natural-creative energy and expression in mental, moral, material
and spiritual and all the other great fields of human activities,
resulting in happiness in life and in work--collectively and
individually--because the conditions of the earning of a livelihood
influence and shape all our mental processes and activities, the quality
and the form of human inter-relationship.

Every human achievement, be it a scientific discovery, a picture, a
statue, a temple, a home or a bridge, has to be conceived in the mind
first--the plan thought out--before it can be made a reality, and when
anything is to be attempted that involves any number of
individuals--methods of coordination have to be considered--the methods
which have proven to be the best suited for such undertakings are
engineering methods--the engineering of _an idea_ toward a complete
_realization_. Every engineer has to know the materials with which he has
to work and the natural laws of these materials, as discovered by
observation and experiment and formulated by mathematics and mechanics;
else he can not calculate the forces at his disposal; he can not compute
the resistance of his materials; he can not determine the capacity and
requirements of his power plant; in short, he can not make the most
profitable use of his resources. Lately in all industries and particularly
