Simple reflex action is an instinctive expression, manifesting an
intuitive perception, almost intelligent, as shown by the contraction of
the stomach upon the food, simply because it impinges upon the inner
coats, and thus excites them to action. A better illustration, because
it displays sympathy, is when the skin, disabled by cold, cannot act,
and its duties are largely performed by the kidneys. Though reflex
action is easily traced in the lower organic processes, some writers
have placed it on a level with rational deliberation. Undoubtedly, all
animals having perception have also what perception
implies--consciousness--and this indicates the possession, in some
degree, of reason. _Compound_ reflex action extends into the domain of
thought. _Simple_ reflex action, or instinct, answers to the animal
faculties, such as acquisitiveness, secretiveness, selfishness,
reproductiveness, etc., and accomplishes two important purposes;
self-preservation and the reproduction of the specie. With many persons,
these appear to be the chief ends of life!
The psychical functions connect, not only with animal propensities, but
also with the highest psychological faculties. Instinct is the
representative of animal conditions, just as the highest spiritual
faculties are indicative of qualities and principles. The consistent
mean of conduct is an equilibrium between these ultimate tendencies of
our being. The psychological functions render the animal nature
subservient to the rule of purity and holiness, and deeply influence it
by the essential elements of spiritual existence. The psychical organs
sustain an intermediate relation, receiving the impressions of the
bodily propensities, and, likewise, of the highest emotions. Obviously,
these extreme influences, the one growing out of animal conditions, the
other, the result of spiritual relations, pass into the psychical medium
and are refracted by it, or made equivalent to one force. The body
requires the qualifying influences of mind. The tendencies of the animal
faculties are selfish and limiting, those of the emotive, general,
universal. The propensities, like gravity, expend their force upon
matter; the emotions pour forth torrents of feeling, and produce
rhapsodies of sentiment. The propensities naturally restrict their
expression to a specific object of sense; the emotions respond to
immaterial being. The tendencies of the former are acquisitive, selfish,
gratifying; of the latter, bestowing, expanding, diffusing. The one
class is restricted to the orbits of time and matter, the other flows on
through the limitless cycles of infinity and immortality. The former is
satiated in animal gratification, the latter in spiritual beatification.
The one culminates in animal enjoyment, the other expands to its
ultimate conceptions in the perfections of Divine Love.
