sire stuff. Carrying our argument to its
logical conclusion, we also hold that unless a World of Thought provides a
reservoir of mind stuff upon which we may draw, it would be impossible for
us to think and invent the things which we see in even the lowest
civilization.

Thus it will be clear that the division of a planet into worlds is not
based on fanciful metaphysical speculation, but is logically necessary in
the economy of nature. Therefore it must be taken into consideration by
any one who would study and aim to understand the inner nature of things.
When we see the street cars moving along our streets, it does not explain
to say that the motor is driven by electricity of so many amperes at so
many volts. These names only add to our confusion until we have thoroughly
studied the science of electricity and then we shall find that the mystery
deepens, for while the street car belongs to the world of _inert form_
perceptible to our vision, the electric current which moves it is
indigenous to the realm of _force_, the invisible Desire World, and the
thought which created and guides it, comes from the still more subtile
World of Thought which is the home world of the human spirit, the Ego.

It may be objected that this line of argument makes a simple matter
exceedingly intricate, but a little reflection will soon show the fallacy
of such a contention. Viewed superficially any of the sciences seem
extremely simple; anatomically we may divide the body into flesh and bone,
chemically we may make the simple divisions between solid, liquid and gas,
but to thoroughly master the science of anatomy it is necessary to spend
years in close application and learn to know all the little nerves, the
ligaments which bind articulations between various parts of the bony
structure, to study the several kinds of tissue and their disposition in
our system where they form the bones, muscles, glands, etc., which in the
aggregate we know as the human body. To properly understand the science of
chemistry we must study the valence of the atom which determines the power
of combination of the various elements, together with other niceties, such
as atomic weight, density, etc. New wonders are constantly opening up to
the most experienced chemist, who understands best the immensity of his
chosen science.

The youngest lawyer, fresh from law school knows more about the most
intricate cases, in his own estimation, than the judges upon the Supreme
