A high regard for the unconscious psyche as a source of knowledge is by no means such a delusion as Western rationalism likes to suppose. Today we know for certain that the unconscious contains contents which would mean an immeasurable increase of knowledge if they could only be made conscious. Modern investigation of animal instinct, as for example in insects, has brought together a rich fund of empirical findings which show that if man acted as certain insects do he would possess a higher intelligence than at present. It cannot, of course, be proved that insects possess conscious knowledge, but common-sense cannot doubt that their unconscious action-patterns are psychic functions. Man?s unconscious likewise contains all the patterns of life and behaviour inherited from his ancestors, so that every human child, prior to consciousness, is possessed of a potential system of adapted psychic functioning. In the conscious life of the adult, as well, this unconscious, instinctive functioning is always present and active. In this activity all the functions of the conscious psyche are prepared for. The unconscious perceives, has purposes and intuitions, feels and thinks, as does the conscious mind. We find sufficient evidence for this in the field of psycho-pathology and the investigation of dream-processes. Only in one respect is there an essential difference between the conscious and the unconscious functioning of the psyche. While consciousness is intensive and concentrated, it is transient and is directed upon the immediate present and the immediate field of attention; moreover, it has access only to material that represents one individual?s experience stretching over a few decades. A wider range of ?memory? is artificially acquired and consists mostly of printed paper. But matters stand very differently with the unconscious. It is not concentrated and intensive, but shades off into obscurity; it is highly extensive and can juxtapose the most heterogeneous elements in the most paradoxical way. More than this, it contains, besides an indeterminable number of subliminal perceptions, an immense fund of accumulated inheritance ? factors left by one generation of men after another, whose mere existence marks a step in the differentiation of the species. If it were permissible to personify the unconscious, we might call it a collective human being combining the characteristics of both sexes, transcending youth and age, birth and death, and, from having at his command a human experience of one or two million years, almost immortal. If such a being existed, he would be exalted above all temporal change; the present would mean neither more nor less to him than any year in the one hundredth century before Christ; he would be a dreamer of age-old dreams and, owing to his immeasurable experience, he would be an incomparable prognosticator. He would have lived countless times over the life of the individual, of the family, tribe and people, and he would possess the living sense of the rhythm of growth, flowering and decay.
Unfortunately ? or rather let us say, fortunately ? this being dreams. At least it seems to us as if the collective unconscious, which appears to us in dreams, had no consciousness of its own contents ? though of course we cannot be sure of this, any more than we are in the case of insects. The collective unconscious, moreover, seems not to be a person, but something like an unceasing stream or perhaps an ocean of images and figures which drift into consciousness in our dreams or in abnormal states of mind.
It would be positively grotesque for us to call this immense system of experience of the unconscious psyche an illusion, for our visible and tangible body itself is just such a system. It still carries within it the discernible traces of primeval evolution, and it is certainly a whole that functions purposively ? for otherwise we could not live. It would never occur to anyone to look upon comparative anatomy or physiology as nonsense. And so we cannot dismiss the collective unconscious as illusion, or refuse to recognise and study it as a valuable source of knowledge.
The psyche appears to us to be essentially a reflection of external happenings ? to be not only occasioned by them, but to have its origin in them. And it also seems to us that the unconscious can be understood only from without and from the side of consciousness. It is well known that Freud has attempted an explanation from this side ? an undertaking which could only succeed if the unconscious were actually something which came into being with the existence and consciousness of the individual. But the truth is that the unconscious is always there beforehand as a potential system of psychic functioning handed down by generations of man. Consciousness is a late-born descendant of the unconscious psyche. It would certainly show perversity if we tried to explain the lives of our ancestors in terms of their late descendants; and it is just as wrong, in my opinion, to regard the unconscious as a derivative of consciousness. We are nearer the truth if we put it the other way round.
