Mental set may be permanent or temporary. By permanent we mean the
strong tendencies that are built up by continued thought in a certain
direction. One becomes a Methodist, a Democrat, a conservative, a
radical, a pessimist, an optimist, etc., by continuity of similar
experiences and similar reactions to these experiences. Germans, French,
Irish, Italians, Chinese, have characteristic sets or ways of reacting
to typical situations that may be called racial. These prejudicial ways
of reacting may be called racial sets or attitudes. Religious,
political, and social prejudices may all be called sets or attitudes.

Temporary sets or attitudes are leanings and prejudices that are due to
temporary states of mind. The fact that one has headache, or
indigestion, or is in a hurry, or is angry, or is hungry, or is
emotionally excited over something will, for the time, be a factor in
determining the direction of association.

One of the tasks of education is to build up sets or attitudes,
permanent prejudices, to be constant factors in guiding association and,
consequently, action. We wish to build up permanent attitudes toward
truth, honesty, industry, sympathy, zeal, persistence, etc. It is
evident that attitude is merely an aspect of habit. It is an habitual
way of reacting to a definite and typical situation. This habitual way
is strengthened by repetition, so that set or attitude finally, after
years of repetition, becomes a part of our nature. Our prejudices become
as strong, seemingly, as our instinctive tendencies. After a man has
thought in a particular groove for years, it is about as sure that he
will come to certain definite conclusions on matters in the line of his
thought as that he would give typical instinctive or even reflex
reactions. We know the direction association will take for a
Presbyterian in religious matters, for a Democrat in political matters,
with about as much certainty as we know what their actions will be in
situations that evoke instinctive reactions.

=Thinking and Reasoning.= Thinking is the passing of ideas in the mind.
This flow of ideas is in accordance with the laws of association above
discussed. The order in which the ideas come is the order fixed by
experience, the order as determined by the various factors above
enumerated.

In early life, one's mind is chiefly perceptual, it is what we see and
hear and taste and smell. As one grows older his mind grow
