this second room the system of the _fore-conscious_. In this way the process of becoming conscious retains its purely descriptive sense. Suppression then, for any individual impulse, consists in not being able to get past the watchman from the system of the unconscious to that of the fore-conscious. The watchman himself is long since known to us; we have met him as the resistance which opposed us when we attempted to release the suppression through analytic treatment. Now I know you will say that these conceptions are as crude as they are fantastic, and not at all permissible in a scientific discussion. I know they are crude--indeed, we even know that they are incorrect, and if we are not very much mistaken we have a better substitute for them in readiness. Whether they will continue then to appear so fantastic to you I do not know. For the time being, they are useful conceptions, similar to the manikin _Ampère_ who swims in the stream of the electric current. In so far as they are helpful in the understanding of our observation, they are by no means to be despised. I should like to assure you that these crude assumptions go far in approximating the actual situation--the two rooms, the watchman on the threshold between the two, and consciousness at the end of the second room in the role of an onlooker. I should also like to hear you admit that our designations--_unconscious_, _fore-conscious_, and _conscious_ are much less likely to arouse prejudice, and are easier to justify than others that have been used or suggested--such as _sub-conscious_, _inter-conscious_, _between-conscious_, etc. This becomes all the more important to me if you should warn me that this arrangement of the psychic apparatus, such as I have assumed in the explanation of neurotic symptoms, must be generally applicable and must hold for normal functioning as well. In that, of course, you are right. We cannot follow this up at present, but our interest in the psychology of the development of the symptom must be enormously increased if through the study of pathological conditions we have the prospect of finding a key to the normal psychic occurrences which have been so well concealed.
