Short answers, pulled from the story.
Jungian archetypes are universal, inherited patterns of thought and image present in the collective unconscious of all human beings, as proposed by Swiss psychiatrist Carl Jung. They are innate, symbolic, psychological expressions that manifest in response to patterned biological instincts and appear across cultures in stories, myths, and dreams. Jung first used the term archetype in his 1919 essay Instinct and the Unconscious.
The personal unconscious holds material specific to an individual, such as forgotten or repressed experiences, while the collective unconscious is a deeper, shared layer inherited by all human beings. Archetypes are units of the collective unconscious; complexes are their counterparts in the personal unconscious. Jung described the collective unconscious as containing universal experiences inherent to the human condition, including belongingness, love, death, and fear.
Jung named the shadow, the wise old man, the child, the mother, the maiden, the anima, and the animus as the chief archetypes of personality. The persona, anima and animus, the shadow, and the self are four archetypes that fall under the separate systems of the personality. He also identified archetypes of events such as birth, death, and marriage, and motifs such as the apocalypse and the deluge.
Individuation is Jung's term for the process by which archetypes guide a person toward self-realization across the stages of life. He described it as the biological process by which every living thing becomes what it was destined to become from the beginning. Stages mediated by archetypal imperatives include being parented, initiation, courtship, marriage, and preparation for death.
Nobel laureate physicist Wolfgang Pauli collaborated with Jung on the concept of the psychoid archetype, a synthesis of instinct and spirit that Pauli believed was crucial to understanding the principles of the universe. Pauli embraced the idea that the archetype provided a link between physical events and the mind of the scientist studying them. Jung used the term unus mundus to describe the unitary reality he believed underlies all manifest phenomena.
Critics argue that archetypes universalize by abstracting myths from their cultural context, reducing complex realities to decontextualized concepts. Modern scholarship has characterized archetypal theory as a Eurocentric and colonialist device, and feminist critics describe it as reductionistic in its view of gender. The theory has also been called scientifically unfalsifiable, and Jung's emphasis on inner experience over empirical data has been characterized as Neo-Kantian subjectivism.
