At this point we may recall the confusing information which Wundt offered us about the double meaning of the word taboo, namely, holy and unclean (see above). It was supposed that originally the word taboo did not yet mean holy and unclean but signified something demonic, something which may not be touched, thus emphasizing a characteristic common to both extremes of the later conception; this persistent common trait proves, however, that an original correspondence existed between what was holy and what was unclean, which only later became differentiated.
In contrast to this, our discussion readily shows that the double meaning in question belonged to the word taboo from the very beginning and that it serves to designate a definite ambivalence as well as everything which has come into existence on the basis of this ambivalence. Taboo is itself an ambivalent word and by way of supplement we may add that the established meaning of this word might of itself have allowed us to guess what we have found as the result of extensive investigation, namely, that the taboo prohibition is to be explained as the result of an emotional ambivalence. A study of the oldest languages has taught us that at one time there were many such words which included their own contrasts so that they were in a certain sense ambivalent, though perhaps not exactly in the same sense as the word taboo[88]. Slight vocal modifications of this primitive word containing two opposite meanings later served to create a separate linguistic expression for the two opposites originally united in one word.
The word taboo has had a different fate; with the diminished importance of the ambivalence which it connotes it has itself disappeared, or rather, the words analogous to it have vanished from the vocabulary. In a later connection I hope to be able to show that a tangible historic change is probably concealed behind the fate of this conception; that the word at first was associated with definite human relations which were characterized by great emotional ambivalence from which it expanded to other analogous relations.
Unless we are mistaken, the understanding of taboo also throws light upon the nature and origin of conscience. Without stretching ideas we can speak of a taboo conscience and a taboo sense of guilt after the violation of a taboo. Taboo conscience is probably the oldest form in which we meet the phenomenon of conscience.
For what is ‘conscience’? According to linguistic testimony it belongs to what we know most surely; in some languages its meaning is hardly to be distinguished from consciousness.
Conscience is the inner perception of objections to definite wish impulses that exist in us; but the emphasis is put upon the fact that this rejection does not have to depend on anything else, that it is sure of itself. This becomes even plainer in the case of a guilty conscience, where we become aware of the inner condemnation of such acts which realized some of our definite wish impulses. Confirmation seems superfluous here; whoever has a conscience must feel in himself the justification of the condemnation, and the reproach for the accomplished action. But this same character is evinced by the attitude of savages towards taboo. Taboo is a command of conscience, the violation of which causes a terrible sense of guilt which is as self-evident as its origin is unknown[89].
It is therefore probable that conscience also originates on the basis of an ambivalent feeling from quite definite human relations which contain this ambivalence. It probably originates under conditions which are in force both for taboo and the compulsion neurosis, that is, one component of the two contrasting feelings is unconscious and is kept repressed by the compulsive domination of the other component. This is confirmed by many things which we have learned from our analysis of neurosis. In the first place the character of compulsion neurotics shows a predominant trait of painful conscientiousness which is a symptom of reaction against the temptation which lurks in the unconscious, and which develops into the highest degrees of guilty conscience as their illness grows worse. Indeed, one may venture the assertion that if the origin of guilty conscience could not be discovered through compulsion neurotic patients, there would be no prospect of ever discovering it. This task is successfully solved in the case of the individual neurotic, and we are confident of finding a similar solution in the case of races.
In the second place we cannot help noticing that the sense of guilt contains much of the nature of anxiety; without hesitation it may be described as ‘conscience phobia’. But fear points to unconscious sources. The psychology of the neuroses taught us that when wish feelings undergo repression their libido becomes transformed into anxiety. In addition we must bear in mind that the sense of guilt also contains something unknown and unconscious, namely the motivation for the rejection. The character of anxiety in the sense of guilt corresponds to this unknown quantity.
If taboo expresses itself mainly in prohibitions it may well be considered self-evident, without remote proof from the analogy with neurosis that it is based on a positive, desireful impulse. For what nobody desires to do does not have to be forbidden, and certainly whatever is expressly forbidden must be an object of desire. If we applied this plausible theory to primitive races we would have to conclude that among their strongest temptations were desires to kill their kings and priests, to commit incest, to abuse their dead and the like. That is not very probable. And if we should apply the same theory to those cases in which we ourselves seem to hear the voice of conscience most clearly we would arouse the greatest contradiction. For there we would assert with the utmost certainty that we did not feel the slightest temptation to violate any of these commandments, as for example, the commandment: Thou shalt not kill, and that we felt nothing but repugnance at the very idea.
But if we grant the testimony of our conscience the importance it claims, then the prohibition—the taboo as well as our moral prohibitions—becomes superfluous, while the existence of a conscience, in turn, remains unexplained and the connection between conscience, taboo and neurosis disappears. The net result of this would then be our present state of understanding unless we view the problem psychoanalytically.
