means of their own personalities alone. It will here be objected that
this is well-known hysterical imitation, the ability of hysteric
subjects to copy all the symptoms which impress them when they occur in
others, as though their pity were stimulated to the point of
reproduction. But this only indicates the way in which the psychic
process is discharged in hysterical imitation; the way in which a
psychic act proceeds and the act itself are two different things. The
latter is slightly more complicated than one is apt to imagine the
imitation of hysterical subjects to be: it corresponds to an unconscious
concluded process, as an example will show. The physician who has a
female patient with a particular kind of twitching, lodged in the
company of other patients in the same room of the hospital, is not
surprised when some morning he learns that this peculiar hysterical
attack has found imitations. He simply says to himself: The others have
seen her and have done likewise: that is psychic infection. Yes, but
psychic infection proceeds in somewhat the following manner: As a rule,
patients know more about one another than the physician knows about each
of them, and they are concerned about each other when the visit of the
doctor is over. Some of them have an attack to-day: soon it is known
among the rest that a letter from home, a return of lovesickness or the
like, is the cause of it. Their sympathy is aroused, and the following
syllogism, which does not reach consciousness, is completed in them: "If
it is possible to have this kind of an attack from such causes, I too
may have this kind of an attack, for I have the same reasons." If this
were a cycle capable of becoming conscious, it would perhaps express
itself in _fear_ of getting the same attack; but it takes place in
another psychic sphere, and, therefore, ends in the realization of the
dreaded symptom. Identification is therefore not a simple imitation, but
a sympathy based upon the same etiological claim; it expresses an "as
though," and refers to some common quality which has remained in the
