Many of the lower animals give unmistakable evidences of the possession
by them of the emotions of anger and fear. Ants, centipedes, tarantulas,
weevils, etc., as well as many of the crustacea will give battle on the
slightest provocation, clearly showing by their actions that anger and
hate are their incentives. When alarmed, their actions indicate very
plainly that the emotion of fear has seized them.

In the next chapter I hope to show that many of the lower animals
possess one or more of the finer emotions, which I have thought best to
group under the head of AEstheticism.

CHAPTER V

AESTHETICISM

"The man that hath not music in himself, nor is not moved with concord
of sweet sounds, is fit for treasons, stratagems, and spoils." The above
quotation is the thought of one of the most acute, profound, and
accurate psychologists that ever lived. That which he observed to be
true among men, strangely enough, a long and systematic course of
observation leads me to believe to be equally true among the lower
animals; for wherever it can be observed that animals evince an
appreciation for musical sounds, or show discrimination in their
perception of harmonious tonal vibrations, such animals, with a single
exception--the spider--will be found to be of kind disposition, and not
given to "treasons, stratagems, and spoils" other than those required by
their struggle for existence. So true is this rule, that the single
exception--the spider--proves the verity of the deduction or conclusion.
For, like many men, the spider's love for the beautiful, not only in
music but in decorative effects as well, is intimately associated with
murder-lust; it kills for the love of killing. Many examples of the
association of great cruelty and profound love for the beautiful in
nature and the arts might be given; it is necessary for my purpose,
however, to give but two--Nero and Catherine de' Medici.

That spiders appreciate musical sounds, and that they can differentiate
between those sounds that are pleasing and those that are disagreeable
to them, I have not a scintilla of doubt. The following facts bearing on
this point came under my own observation or were told me by people in
whose veracity I believe implicitly, or are vouched for by scientists of
world-wide fame.
