It is my opinion that the importance of unconscious operations[208] in legal procedure is undervalued. We could establish much that is significant concerning an individual whose unconscious doings we knew. For, as a rule, we perform unconsciously things that are deeply habitual, therefore, first of all what everybody does--walk, greet your neighbor, dodge, eat, etc.; secondly, we perform unconsciously things to which we have become accustomed in accordance with our especial characters.[209] When, during my work, I rise, get a glass of water, drink it, and set the glass aside again, without having the slightest suspicion of having done so, I must agree that this was possible only in my well-known residence and environment, and that it was possible to nobody else, not so familiar. The coachman, perhaps, puts the horses into the stable, rubs them down, etc., and thinks of something else while doing so. He has performed unconsciously what another could not. It might happen that I roll a cigarette while I am working, and put it aside; after awhile I roll a second and a third, and sometimes I have four cigarettes side by side. I needed to smoke, had prepared a cigarette, and simply because I had to use my hands in writing, etc., I laid the cigarette aside. In consequence, the need to smoke was not satisfied and the process was repeated. This indicates what complicated things may be unconsciously performed if only the conditions are well-known; but it also indicates what the limits of unconscious action are: e.g., I had not forgotten what would satisfy my need to smoke, nor where my cigarette paper was, nor how to make a cigarette, but I had forgotten that I had made a cigarette without having smoked it. The activities first named have been repeated thousands of times, while the last had only just been performed and therefore had not become mechanical.[210] Lipps calls attention to another instance: “It may be that I am capable of retaining every word of a speech and of observing at the same time the expression which accompanies the speech. I might be equally able to trace a noise which occurs on the street and still to pay sufficient attention to the speech. On the other hand, I should lose the thread of the speech if I were required at the same time to think of the play of feature and the noise. Expressed in general terms, idea A may possibly get on with idea B and even idea C; but B and C together make A impossible. This clearly indicates that B and C in themselves have opposed A and inhibited it in some degree, but that only the summation of their inhibition could serve really to exclude A.” This is certainly correct and may perhaps be more frequently made use of when it is necessary to judge how much an individual would have done at one and the same time, and how much he would have done unconsciously. An approximation of the possibilities can always be made.
