s, already give evidence not only of
intense sentiments of sympathy and antipathy, anger and jealousy, but
also of commiseration, when they see those whom they love suffer; they
may even show that they already possess the sentiment of duty or
disinterested devotion. All these phylogenetic derivatives of the
sentiments of sexual attraction are thus developed in the individual
long before the sexual instinct itself, from which they have become
absolutely independent. This does not prevent them being powerfully
influenced by the sexual instinct when this awakes, or from being
associated with its direct derivatives when the sexual appetite,
properly so-called, is absent. Thus we see absolutely cold women
become loving and devoted wives and mothers, and possessing a highly
developed sense of kinship. Maternal love is a sentiment of sympathy
derived from the sexual sentiment, adapted directly to children, who
are the products of sexual life.

=Constellations.=--From all this results the immense complication of
the peculiarities of the human mind which are connected with love.
Individual variations of the disposition to sexual appetite are
combined with individual dispositions to the higher qualities of
mind--general sentiments, intelligence and will--to form the most
diverse individual combinations, which we may call _constellations_.
Moreover, inherited individual dispositions are combined in man with a
great number of experiences and remembrances, acquired in all domains
in the course of his life, accumulating them in his brain by what is
called education or adaptation to environment. From the immense
complexity of energies resulting from hereditary dispositions combined
with acquired factors, the resolutions and acts of man are derived,
without his being able to account for the infinite multiplicity of
causes which determine them.

It is thus that a man may be a model of conduct or morality, simply
from the fact that his sexual appetite is almost nil. Another, on the
contrary, suffers from an exaggerated sexual appetite, but is devoted,
conscientious, and even scrupulous; this results in violent internal
struggles, from which he does not always emerge victorious. A third is
moderate in his appetites; if his sentiment of duty is strong and he
possesses a strong will, he will resist his desires, while if his will
is weak or his moral sense defective, he will succumb to the first
temptation.

Love and sexual appetite may
