the victims of this emotional catastrophe are pitied by the inmates of
the lowest inferno.

He or she who has been so unfortunate as to experience the pangs--or
fangs--of jealousy will readily admit that it is one of the most
painful, if indeed _not_ the most painful, of all human emotions. The
suffering that it metes out to its victims is indescribable. No other
single human emotion so affects the body, so upsets the mind, so
deranges every function, as does jealousy. The torture that it causes
makes the sufferer a truly pitiable object: the complete loss of sleep
and complete loss of appetite may result in a serious impairment of
the sufferer's health, while the rage it often gives rise to may lead
to actual insanity, or at least to great mental disturbance. With good
reason has popular fancy pictured this cursed emotion as a green-eyed
monster.

Jealousy is a primitive emotion. It is present not only in the
primitive races, but even in animals. And being a primitive emotion,
we can hardly hope to succeed in eradicating it entirely. Not in the
immediate future, at any rate. But we can modify it.

The statement frequently heard that "human nature is human nature" is
only a platitudinous half-truth. The fundamental part of human
nature--the desire for happiness and the avoidance
