S 18.--Second Law.


All that has been said of the transferrence of the mental sensations to
the animal holds true of the transferrence of animal affections to the
mental. Bodily sickness--for the most part the natural result of
intemperance--brings its punishment in the form of bodily pain; but the
mind also cannot escape a radical attack, in order that a twofold pain
may more powerfully impress upon it the necessity of restraint in the
desires. In like manner the feeling of bodily health is accompanied by a
more lively consciousness of mental improvement, and man is thus the more
spurred on to maintain his body in good condition. We arrive thus at a
second law of mixed natures--that, with the free action of the bodily
organism, the sensations and ideas gain a freer flow; and learn that,
with a corrupted organism, corruption of the thinking faculty and of the
sensations inevitably follows. Or, more shortly, that the general
sensation of a harmonious animal life is the fountain of mental pleasure,
and that animal pain and sickness is the fountain of mental pain.

In these different respects, or from their consideration, soul and body
may not unaptly be compared with two stringed instruments tuned by the
same hand, and placed alongside of one another. When a string of one of
them is touched and a certain tone goes forth, the corresponding string
of the other will sound of itself and give the same tone, only somewhat
weaker. And, using this comparison, we may say that the string of
gladness in the body wakes the glad string in the soul, and the sad
string the string of sadness. This is that wonderful and noteworthy
sympathy which unites the heterogeneous principles in man so as to form
one being. Man is not soul and body--but the most inward and essential
blending of the two.
