of his soul".

The "expansion of the self" is an interesting and significant
phenomenon. The individual comes to call things, persons, social
groups, ideas and principles by the name {558} "mine". Now what is
mine is part of me. My self-feeling attaches to my dog; I am proud of
that dog, brag of his exploits, am cast down if I see him outclassed;
and it is the same way with my house, my son, my town, my country. We
spoke of this sort of thing before, under the name of "sublimation of
the self-assertive impulse", and we said then that the sublimation was
made possible by the combination of this impulse with some other
interest. My dog is not entirely myself; he is a dog, and I am
interested in him as a dog; I am interested in other dogs, and like to
watch their antics. But this particular dog means more than another to
me because he is mine; I have expanded myself to include him. In
general, the self is expanded to take in objects that are interesting
in themselves, but which become doubly interesting by being
appropriated and identified in some measure with oneself.

Integration and Disintegration of the Personality

Though the individual is always in one sense a unit, there is a sense
in which he needs to achieve unity. His various native tendencies and
interests do not always pull together, and in fact some necessarily
pull against others. So that we sometimes say of a person that he is
behaving so differently from usual that we should not know he was the
same person. We may speak of one person as being well integrated,
meaning that he is always himself, his various tendencies being so
cooerdinated as to work reasonably well together; whereas of another we
speak as poorly integrated, unstable, an uncertain quantity.
Integration is achieved partly by selection from among conflicting
impulses, partly by cooerdination, partly by judicious treatment of
those impulses that are denied; as was partly explained in the last
chapter.

{559}

The self, expanding socially, may expand in more than one direction,
with the result that the individual has in a sense two or more selves,
one for his business, one for his home; and it may happen that the
instincts and interests dominating the individual in these two
relations are quite different, so that a man who is hard and grasping
in business is kind and generous to his wife and children. "Dr. Jekyll
and Mr. Hyde" gives an extreme picture of such lack of integration, a
pict
