The Collective Unconscious: Jung’s Theory Explained

What is the collective unconscious?

Jung divided the unconscious into two layers. The personal unconscious holds what an individual has forgotten, repressed or perceived without noticing. The collective unconscious lies deeper, and Jung described it as universal rather than individual: its contents and patterns of behavior are roughly the same everywhere and in every person.

Jung compared it to the body. Just as the human body carries the marks of its evolutionary history, the psyche is born with an inherited structure. He stressed that what is inherited is not a set of memories or ready-made ideas, but predispositions: tendencies to form certain kinds of images and to react to typical situations, such as birth, danger, love, loss and death, in typical ways. In this sense he described the archetypes as close relatives of the instincts.

He used the term from about 1916, in the essay “The Structure of the Unconscious”, and gave his fullest account in “The Archetypes and the Collective Unconscious” (1934) and in a lecture in London, “The Concept of the Collective Unconscious” (1936). Both are collected in Volume 9, Part I of his Collected Works.

Personal unconscious and collective unconscious

The difference is easiest to see side by side.

Personal unconscious

Made of material that was once conscious or could have been: forgotten experiences, repressed wishes, subliminal perceptions. Its typical contents are complexes, emotionally charged clusters of memories. It differs from person to person.

Collective unconscious

Never acquired by the individual. Its contents, the archetypes, have never been conscious as such and become visible only as images: the mother, the hero, the wise old man, the shadow, the divine child. It is common to all people.

This is also one of the main points where Jung parted from Freud. For Freud the unconscious was mostly personal and filled with repressed material, although in later works such as Moses and Monotheism (1939) he also spoke of an archaic heritage. Jung made the inherited, shared layer the center of his psychology.

How Jung arrived at the idea

Jung traced the idea to a dream he had in 1909, while travelling to the United States with Freud. He was in a house: the upper floor was furnished in eighteenth century style, the ground floor was medieval, a stairway led down to a Roman cellar, and below that he found a cave with scattered bones and broken pottery. He understood the house as an image of the psyche, with older and more impersonal layers beneath the personal ones.

His clinical work pointed the same way. At the Burghölzli he met patients whose delusions contained mythological motifs they had apparently never read about. The best known is the so-called solar phallus man: a patient who said he could see a tube hanging from the sun, and that its movement made the wind blow. Jung later found a strikingly similar image in an ancient Greek magical papyrus published by the philologist Albrecht Dieterich.

The case is famous, and also contested. Critics have pointed out that Dieterich’s edition was already in print before the patient was observed, and that the case was first written up by Jung’s younger colleague Johann Jakob Honegger. For Jung’s critics this shows how difficult it is to rule out hidden learning; for his defenders the case is only one of many parallels.

What evidence did Jung point to?

Jung’s main argument was comparative. He collected recurring motifs from mythology, religion, alchemy, folklore, children’s dreams and the fantasies of psychotic patients, and showed that they repeat across cultures with no obvious contact: the great flood, the descent of the hero into the underworld, the miraculous birth of a divine child, the world tree, the devouring and nourishing great mother, death followed by rebirth.

To work with such images he used a method he called amplification: placing a dream image beside parallel images from myths and other cultures to bring out its typical meaning. Earlier thinkers had noticed similar patterns, for example the nineteenth century ethnologist Adolf Bastian with his theory of “elementary ideas” shared by all peoples. Jung’s step was to locate the source of these patterns in the structure of the psyche itself.

What the collective unconscious is not

Popular accounts often blur the idea, so a few distinctions help. The collective unconscious is not a group mind or a crowd mentality, and it is not inherited memory of specific events. It is also not the same as Émile Durkheim’s “collective consciousness”, a sociological term for the shared beliefs and norms that hold a society together.

In his late work Jung did speculate more boldly. In “On the Nature of the Psyche” (1947) he described the archetypes as psychoid, meaning that they reach beyond the psyche toward the body and matter, and in connection with synchronicity he wrote of an underlying unity of psyche and world, the unus mundus. These ideas remain the most debated part of his thought.

Criticism and modern views

The theory has been criticized since Jung’s lifetime. The central objection is that it is hard to test: similar motifs in different cultures can also be explained by cultural diffusion, by universal human experiences (everyone sees the sun, everyone is born and dies) or by hidden learning. The historian Richard Noll went further and argued that Jung’s movement had features of a religious cult, a reading most Jung scholars reject.

Other researchers have tried to restate the idea in modern terms. The psychiatrist Anthony Stevens linked the archetypes to ethology and evolutionary psychology in Archetype: A Natural History of the Self (1982). The analyst Jean Knox argued in Archetype, Attachment, Analysis (2003) that archetypes are better understood as patterns that emerge reliably in early development, similar to the image schemas studied in cognitive science, rather than as inherited images. The cognitive science of religion, which studies innate tendencies such as detecting agents behind events, reaches some conclusions that echo Jung while using very different methods.

The collective unconscious today

Whatever its scientific status, the idea remains alive in Jungian analysis, in art and film criticism, in religious studies and in the way many people think about their dreams. Joseph Campbell’s hero’s journey, which shaped modern storytelling, is one of its best known descendants.

Archetype Matrix takes a modest, practical angle on it. People log the images that keep returning to them, such as a snake, a forest or an old woman, and the app counts how often the same image appears in different countries and moods. Counting does not prove Jung right. It simply makes visible which images keep surfacing in many minds at once.
