erstood. Is this not true of the individual? Do we not all recognize
in the moods and mental attitudes and even in some of the actions of the
adult, remnants of feelings and forces which were dynamic in childhood?
These feelings exist although they are not consciously appreciated. The
actual experiences are forgotten but the moods and emotions remain. This
is analagous to the influence which primitive racial thoughts, beliefs
and usages have on present day civilization. The meaning of these usages
and symbols is forgotten in many cases but the outward form still
exists.

In the individual, a motive of this kind does not become a religion or a
ritual as in the case with the race, but it nevertheless is forcefully
expressed in that it excites an absorbing interest and forces itself
strongly into consciousness, during the phase of its dynamic
development. As stated above, just as in the early mental evolution of
the race, we find that the question of reproduction comes prominently to
the fore, so with the individual we find that at the adolescent period
of life the sexual instinct is very fully elaborated. Just as with the
race reproduction is necessary for the continuation of the race, so with
the individual, elaboration of sexual instinct is necessary in order
that adult sexual responsibilities may be assumed. This consists of much
more than mere physical development. In a complex state of civilization
many adjustments in the sphere of sexual indulgence and continence and
marriage have to be made. This phase of the individual's life is a very
important one. It is the rule for proper reactions to occur at this
time, in which case the reproductive instincts assume their proper place
in mental life. But if satisfactory adjustments do not occur the
consequences may be serious. In the healthy mental evolution of the
individual, therefore, just as in the normal mental evolution of the
race, we see that motives arise, assume a dynamic character, play their
part in the developing mind, and leave lasting impressions. They serve a
useful purpose during one phase of mental evolution. We have seen that
they may be harmful in the race if utilized at a later period. Let us
see to what extent this is true of the individual.

Psychiatrists during recent years have come to believe that in certain
mental states we see a reversion to a more primitive type of
reaction,--a tendency to utilize earli
