handicapped by abnormal conditions for which they were never
fashioned. We were written in a major key, and when we try to change
over into minor tones we get sadly out of tune.

There is another factor; painful emotions make us fall to pieces,
while pleasant emotions bind us together. We can see why this is so
when we remember that powerful emotions like fear and anger tend to
dissociate all but themselves, to split up the mind into separate
parts and to force out of consciousness everything but their own
impulse. Morton Prince in his elaborate studies of the cases of
multiple personality, Miss Beauchamp and B.C.A., found repeatedly that
he had only to hypnotize the patient and replace painful, depressing
complexes by healthy, happy ones to change her from a weak, worn-out
person, complaining of fatigue, insomnia, and innumerable aches and
pains, into a vigorous woman, for the time being completely well. On
this point he says:

Exalting emotions have an intense synthesizing effect, while
depressing emotions have a disintegrating effect. With the
inrushing of depressive memories or ideas ... there is suddenly
developed a condition of fatigue, ill-being and disintegration,
followed after waking by a return or accentuation of all the
neurasthenic symptoms. If on the other hand, exalting ideas and
memories are introduced and brought into the limelight of
attention, there is almost a magical reversal of processes. The
patient feels strong and energetic, the neurasthenic symptoms
disappear and he exhibits a capacity for sustained effort. He
becomes re-vitalized, so to speak.[29]
