One of the most uncanny and widespread forms of superstition is the dread of the evil eye, which has been exhaustively studied by the Hamburg oculist Seligmann (1910-11). There never seems to have been any doubt about the source of this dread. Whoever possesses something that is at once valuable and fragile is afraid of other people’s envy, in so far as he projects on to them the envy he would have felt in their place. A feeling like this betrays itself by a look even though it is not put into words; and when a man is prominent owing to noticeable, and particularly owing to unattractive, attributes, other people are ready to believe that his envy is rising to a more than usual degree of intensity and that this intensity will convert it into effective action. What is feared is thus a secret intention of doing harm, and certain signs are taken to mean that that intention has the necessary power at its command.

These last examples of the uncanny are to be referred to the principle which I have called ‘omnipotence of thoughts’, taking the name from an expression used by one of my patients. And now we find ourselves on familiar ground. Our analysis of instances of the uncanny has led us back to the old, animistic conception of the universe. This was characterized by the idea that the world was peopled with the spirits of human beings; by the subject’s narcissistic overvaluation of his own mental processes; by the belief in the omnipotence of thoughts and the technique of magic based on that belief; by the attribution to various outside persons and things of carefully graded magical powers, or ‘mana’; as well as by all the other creations with the help of which man, in the unrestricted narcissism of that stage of development, strove to fend off the manifest prohibitions of reality. It seems as if each one of us has been through a phase of individual development corresponding to this animistic stage in primitive men, that none of us has passed through it without preserving certain residues and traces of it which are still capable of manifesting themselves, and that everything which now strikes us as ‘uncanny’ fulfils the condition of touching those residues of animistic mental activity within us and bringing them to expression.

At this point I will put forward two considerations which, I think, contain the gist of this short study. In the first place, if psychoanalytic theory is correct in maintaining that every affect belonging to an emotional impulse, whatever its kind, is transformed, if it is repressed, into anxiety, then among instances of frightening things there must be one class in which the frightening element can be shown to be something repressed which recurs. This class of frightening things would then constitute the uncanny; and it must be a matter of indifference whether what is uncanny was itself originally frightening or whether it carried some other affect. In the second place, if this is indeed the secret nature of the uncanny, we can understand why linguistic usage has extended das Heimliche [‘homely’] into its opposite, das Unheimliche; for this uncanny is in reality nothing new or alien, but something which is familiar and old-established in the mind and which has become alienated from it only through the process of repression. This reference to the factor of repression enables us, furthermore, to understand Schelling’s definition of the uncanny as something which ought to have remained hidden but has come to light.

It only remains for us to test our new hypothesis on one or two more examples of the uncanny.

Many people experience the feeling in the highest degree in relation to death and dead bodies, to the return of the dead, and to spirits and ghosts. As we have seen some languages in use to-day can only render the German expression ‘an unheimlich house’ by ‘a haunted house’. We might indeed have begun our investigation with this example, perhaps the most striking of all, of something uncanny, but we refrained from doing so because the uncanny in it is too much intermixed with what is purely gruesome and is in part overlaid by it. There is scarcely any other matter, however, upon which our thoughts and feelings have changed so little since the very earliest times, and in which discarded forms have been so completely preserved under a thin disguise, as our relation to death. Two things account for our conservatism: the strength of our original emotional reaction to death and the insufficiency of our scientific knowledge about it. Biology has not yet been able to decide whether death is the inevitable fate of every living being or whether it is only a regular but yet perhaps avoidable event in life. It is true that the statement ‘All men are mortal’ is paraded in text-books of logic as an example of a general proposition; but no human being really grasps it, and our unconscious has as little use now as it ever had for the idea of its own mortality. Religions continue to dispute the importance of the undeniable fact of individual death and to postulate a life after death; civil governments still believe that they cannot maintain moral order among the living if they do not uphold the prospect of a better life hereafter as a recompense for mundane existence. In our great cities, placards announce lectures that undertake to tell us how to get into touch with the souls of the departed; and it cannot be denied that not a few of the most able and penetrating minds among our men of science have come to the conclusion, especially towards the close of their own lives, that a contact of this kind is not impossible. Since almost all of us still think as savages do on this topic, it is no matter for surprise that the primitive fear of the dead is still so strong within us and always ready to come to the surface on any provocation. Most likely our fear still implies the old belief that the dead man becomes the enemy of his survivor and seeks to carry him off to share his new life with him. Considering our unchanged attitude towards death, we might rather enquire what has become of the repression, which is the necessary condition of a primitive feeling recurring in the shape of something uncanny. But repression is there, too. All supposedly educated people have ceased to believe officially that the dead can become visible as spirits, and have made any such appearances dependent on improbable and remote conditions; their emotional attitude towards their dead, moreover, once a highly ambiguous and ambivalent one, has been toned down in the higher strata of the mind into an unambiguous feeling of piety.

We have now only a few remarks to add — for animism, magic and sorcery, the omnipotence of thoughts, man’s attitude to death, involuntary repetition and the castration complex comprise practically all the factors which turn something frightening into something uncanny. . .
