Movements.

As, according to the testimony of Herr von Haller, activity of mind
during the day tends to quicken the pulse towards evening, will not
indolence of mind make it more sluggish, and absolute inactivity
completely stop it? For, although the circulation of the blood does not
seem to be so very dependent on the mind, is it altogether unreasonable
to suppose that the heart, which, in any case, borrows from the brain the
larger portion of its strength, must necessarily, when the soul ceases to
maintain the action of the brain, suffer thereby a great loss of power?
A condition of phlegm is accompanied by a sluggish pulse, the blood is
thin and watery, and the circulation defective in the abdomen. The
idiots, whom Muzell has described for us [Muzell's "Medical and Surgical
Considerations."], breathed slowly and with difficulty, had no
inclination to eat and drink, nor to the natural functions; the pulse was
slow, all bodily movements slumberous and indicative of weariness. The
mental numbness which is the result of terror or wonder is sometimes
accompanied by a general suspension of all natural physical activity.
Was the mind the origin of this condition, or was it the body which
brought about this torpid state of mind? But these considerations lead
to subtleties and intricate questions, and, besides, must not be
discussed in this place.

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.
