to consist, in a certain effort to contract themselves on the touch
of some external provocation. These two principles go to form the
specific character of animal organism.

The second class of powers embraces those which we can account for by the
universally-known laws of physics. Among these I reckon the mechanism of
motion, and the chemistry of the human body, the source of vegetable
life. Vegetation, then, and animal mechanism, thoroughly mingled, form
the proper physical life of the human body.

S 4.-Animal Life.

This is not yet all. Since loss or misfortune, when it occurs, falls
more or less within the will-power of the spirit, the spirit must be
able to make some compensation for it. Further, since the body is
subjected to all the consequences of this connection, and in the circle
of circumstances is exposed to countless hostile forces, it must be
within the power of the soul to protect the body against these harmful
influences, and to bring it into such relations with the physical
world as shall tend most to its preservation. The soul must therefore
be conscious of the present evil or good state of its organs; from a
bad state it must draw dissatisfaction, from a good state satisfaction,
so that it may either retain or remove the condition, seek it or fly
from it. Here then we have the organism at once and closely linked to
the sensational capacity, and the soul drawn into the service of the
body. We have now something more than vegetation, something more than a
dead model and the mechanism of nerves and muscles. Now we have animal
life. [1]

A healthy condition of our animal life is, as we know, most important for
the healthy condition of our spiritual life; and we dare never ignore the
animal life so long as we are not quit of it. It must therefore possess
a firm foundation, not easily moved; that is, the soul must be fitted and
prepared for the actions of our bodily life by an irresistible power.
Were then the sensations of our animal loss or well-being to become
spiritual perceptions, and had they to be created by thought, how often
would the soul be obscured by the overwhelming blaze of passion; how
often stifled by laziness and stupidity; how often overlooked in the
absorptions and distractions of business! Further, would not, in this
case, the most perfect knowledge of his economy be demanded of the animal
man--would not the child need to be a master in a branch of knowledge in
which, after f
