opposed to the aim and the direction of the work.
"But in the general plan of the work and functions of the human machine there are
certain points in which a change may be brought about without giving rise to any
supplementary results.
"It is necessary to know what these points are and it is necessary to know how to
approach them, for if one does not begin
"Having fixed in his own mind the difference between the intellectual, the
emotional, and the moving functions, a man must, as he observes himself,
immediately refer his impressions to this or that category. And at first he must take
mental note of only such observations as regards which he has no doubt whatever,
that is, those where he sees at once to what category they belong. He must reject all
vague or doubtful cases and remember only those which are unquestionable. If the
work is carried on properly, the number of unquestionable observations will rapidly
increase. And that which seemed doubtful before will be clearly seen to belong to the
first, the second, the third center. Each center has its own memory, its own
associations, its own thinking. As a matter of fact each center consists of three parts:
the thinking, the emotional, and the moving. But we know very little about this side of
our nature. In each center we know only one part. Self-observation, however, will
very quickly show us that our mental life is much richer than we think, or in any case
that it contains more possibilities than we think.
"At the same time as we watch the work of the centers we shall observe, side by
side with their right working, their wrong working, that is, the working of one center
for another; the attempts of the thinking center to feel or to pretend that it feels, the attempts of the emotional center to think, the attempts of the moving center to think
and feel. As has been said already, one center working for another is useful in certain
cases, for it preserves the continuity of mental activity. But in becoming habitual it
becomes at the same time harmful, since it begins to interfere with right working by
enabling each center to shirk its own direct duties and to do, not what it ought to be
doing, but what it likes best at the moment. In a normal healthy man each center does
its own work, that is, the work for which it was specially destined and which it can
best perform. There are situations in life which the thinking center alone can deal with
and can find a way out of. If at this moment the emotional center begins to work
instead, it will make a muddle of everything and the result of its interference will be
most unsatisfactory. In an 'unbalanced kind of man the substitution of one center for
another goes on almost continually and this is precisely what 'being unbalanced' or
'neurotic' means. Each center strives, as it were, to pass its work on to another, and, at the same time, it strives to do the work of another center for which it is not fitted. The emotional center working for the thinking center brings unnecessary nervousness,
feverishness, and hurry into situations where, on the con-
trary, calm judgment and deliberation are essential. The thinking center working for
the emotional center brings deliberation into situations which require quick decisions
and makes a man incapable of distinguishing the peculiarities and the fine points of
the position. Thought is too slow. It works out a certain plan of action and continues
to follow it even though the circumstances have changed and quite a different course
of action is necessary. Besides, in some cases the interference of the thinking center
gives rise to entirely wrong reactions, because the thinking center is simply incapable
of understanding the shades and distinctions of many events. Events that are quite
different for the moving center and for the emotional center appear to be alike to it. Its decisions are much too general and do not correspond to the decisions which the
emotional center would have made. This becomes perfectly clear if we imagine the
interference of thought, that is, of the theoretical mind, in the domain of feeling, or of sensation, or of movement; in all three cases the interference of the mind leads to
wholly undesirable results. The mind cannot understand shades of feeling. We shall
see this clearly if we imagine one man reasoning about the emotions of another. He is
not feeling anything himself so the feelings of another do not exist for him. A
is it capable of controlling movement. Instances of this kind are the easiest to find.
Whatever work a man may be doing, it is enough for him to try to do each action
