In answer to this question my experiences leave me in the lurch. I can only urge against considering the demonstrated connections as rare, for as often as I have made the test in myself and with my patients it was always definitely demonstrated exactly as in the examples reported, or there were at least good reasons to assume this. One should not be surprised, however, when one does not succeed every time in finding the concealed meaning of the symptomatic action, as the amount of inner resistances ranging themselves against the solution must be considered a deciding factor. Also it is not always possible to explain every individual dream of one’s self or of patients. To substantiate the general validity of the theory, it is enough if one can penetrate only a certain distance into the hidden associations. The dream which proves refractory when the solution is attempted on the following day can often be robbed of its secret a week or a month later, when the psychic factors combating one another have been reduced as a consequence of a real change that has meanwhile taken place. The same applies to the solution of faulty and symptomatic actions. It would therefore be wrong to affirm of all cases which resist analysis that they are caused by another psychic mechanism than that here revealed; such assumption requires more than negative proofs; moreover, the readiness to believe in a different explanation of faulty and symptomatic actions, which probably exists universally in all normal persons, does not prove anything; it is obviously an expression of the same psychic forces which produced the secret, which therefore strives to protect and struggle against its elucidation. On the other hand, we must not overlook the fact that the repressed thoughts and feelings are not independent in attaining expression in symptomatic and faulty actions. The technical possibility for such an adjustment of the innervations must be furnished independently of them, and this is then gladly utilized by the intention of the repressed material to come to conscious expression. In the case of linguistic faulty actions an attempt has been made by philosophers and philologists to verify through minute observations what structural and functional relations enter into the service of such intention. If in the determinations of faulty and symptomatic actions we separate the unconscious motive from its co-active physiological and psychophysical relations, the question remains open whether there are still other factors within normal limits which, like the unconscious motive, and in its place can produce faulty and symptomatic actions on the road of the relations. It is not my task to answer this question.
