In other words, continuing the metaphor of the trained army, we see
millions upon millions of molecules all arranged in regiments, distinct
and separate, and the regiments again made up of companies or
individuals, each obeying his own orders in subordination to, and in
harmony with, the whole: are we not justified in concluding that this
army has not been only called into being by some cause external to
itself; but further, that its constitution has been impressed upon it,
and its equipments and organization directed, by an Infinite
Intelligence?

There is, then, no such thing to be found in Nature as a simple,
structureless "primal matter" which exhibits nothing tending to make
self-causation or aboriginal existence difficult to conceive. To look at
matter in that light is not only to take into consideration a _part_ of
the case; it is really to take what does not exist, a part that exists
only in the imagination. The simplest form of matter we can deal with,
exhibits within itself all the wondrous plan, law, and sequence of the
molecular and atomic structure we have sketched out; and when we
consider that, having taken matter so far, we have even then only
introduced it to the verge of the universe, ushered it on to the
threshold of a great "aeon," when and where it is to be acted on by
"gravitation" and other forces, to act in relation to other matter, and
to be endowed perhaps with LIFE, we shall feel that the
self-existence--the uncaused existence of matter, and of the principles
on which matter proceeds or acts, is in reality not a less mystery than
the self-existence of a Designing and Intelligent Cause, but one so
great as to be itself "unthinkable."
