s the system of management and control throw responsibility on the
pupils in a way to develop their powers of will?

6. What motives or incentives can be used to encourage pupils to use
self-compulsion to maintain high standards of excellence in their
studies and conduct? Does it pay to be heroic in one's self-control?

CHAPTER XVIII

SELF-EXPRESSION AND DEVELOPMENT

We have already seen that the mind and the body are associated in a
copartnership in which each is an indispensable and active member. We
have seen that the body gets its dignity and worth from its relation
with the mind, and that the mind is dependent on the body for the crude
material of its thought, and also for the carrying out of its mandates
in securing adaptation to our environment. We have seen as a corollary
of these facts that the efficiency of both mind and body is conditioned
by the manner in which each carries out its share of the mutual
activities. Let us see something more of this interrelation.

1. INTER-RELATION OF IMPRESSION AND EXPRESSION

_No impression without corresponding expression_ has become a maxim in
both physiology and psychology. Inner life implies self-expression in
external activities. The stream of impressions pouring in upon us hourly
from our environment must have means of expression if development is to
follow. We cannot be passive recipients, but must be active participants
in the educational process. We must not only be able to _know_ and
_feel_, but to _do_.

THE MANY SOURCES OF IMPRESSIONS.--The nature of the impressions which
come to us and how they all lead on toward ultimate expression is shown
in the accompanying diagram (Fig. 20). Our material environment is
thrusting impressions upon us every moment of our life; also, the
material objects with which we deal have become so saturated with social
values that each comes to us with a double significance, and what an
object _means_ often stands for more than what it _is_. From the lives
of people with whom we daily mingle; from the wider circle whose lives
do not immediately touch ours, but who are interpreted to us by the
press, by history and literature; from the social institutions into
which have gone the lives of millions, and of which our lives form a
part, there come to us constantly a flood of impressions whose influence
cannot be measured. So likewise with religious impressions. God is all
about us and within us. He
