Archetypal psychology relativizes and deliteralizes the notion of ego and focuses on what it calls the psyche, or soul,
 and the deepest patterns of psychic functioning, "the fundamental 
fantasies that animate all life" (Moore, in Hillman, 1991). Archetypal 
psychology likens itself to a polytheistic mythology in that it attempts
 to recognize the myriad fantasies and myths
 – gods, goddesses, demigods, mortals and animals – that shape and are 
shaped by our psychological lives. In this framework the ego is but one 
psychological fantasy within an assemblage of fantasies. Archetypal 
psychology is, along with the classical and developmental schools, one 
of the three schools of post-Jungian psychology outlined by Andrew Samuels (see Samuels, 1995).
Influences
The main influence on the development of archetypal psychology is Carl Jung's analytical psychology. It is strongly influenced by Classical Greek, Renaissance, and Romantic ideas and thought. Influential artists, poets, philosophers and psychologists include: Nietzsche, Henry Corbin, Keats, Shelley, Petrarch, and Paracelsus. Though all different in their theories and psychologies, they appear to be unified by their common concern for the psyche – the soul.
C. G. Jung
Carl Gustav Jung was a Swiss psychologist who was the first father of archetypal psychology. Jungian archetypes
 are thought patterns that find worldwide parallels in individuals or 
entire cultures. Archai appear in dreams, religions, the arts, and 
social customs in all people and they manifest impulsively in mental 
disorders. According to Jung archetypal ideas and patterns reside within the collective unconscious, which is a blueprint inherent in every individual, as opposed to the personal unconscious, which contains a single individual's repressed ideas, desires and memories as described by Freud.
 What differentiates Jungian psychology from archetypal psychology is 
that Jung believed archetypes are cultural, anthropological, and 
transcend the empirical world of time and place, and are not phenomenal.
 On the contrary, Archetypal psychology views archetypes to always be 
phenomenal.
Henry Corbin
Henry Corbin,
 a French scholar and philosopher, is the second father of archetypal 
psychology. Corbin created the idea of the existence of the mundus imaginalis which is a distinct field of imaginable realities and offers an ontological mode of location of archetypes of the psyche.
 The mundus imaginalis provided an evaluative and cosmic grounding for 
archetypes. The second contribution Corbin made to the field was the 
idea that archetypes are accessible to imagination and first present 
themselves as images, so the procedure of archetypal psychology must be 
rhetorical and poetic, without logical reasoning, and the goal in 
therapy should be to restore the patient's imaginable realities. 
Therefore, the goal of therapy is the middle ground of psychic 
realities, a development of a sense of soul. Also, according to Corbin, 
the method of therapy is the cultivation of imagination.
Edward Casey
Edward S. Casey
 is attributed with distinguishing archetypal psychology from other 
theories by explaining an image as a way of seeing rather than something
 seen. According to Casey an image is only perceived by imagining 
because an image is not what one sees but the way one sees. He also 
states that imagination is an activity of soul and not just a human 
faculty. An image appears to be more profound, more powerful, and more 
beautiful than the comprehension of it. This explains the drive behind 
the arts which provide disciplines that can actualize the complexity of 
the image.
James Hillman
Hillman (1975) sketches a brief lineage of archetypal psychology.
By calling upon Jung to begin with, I am partly acknowledging the fundamental debt that archetypal psychology owes him. He is the immediate ancestor in a long line that stretches back through Freud, Dilthey, Coleridge, Schelling, Vico, Ficino, Plotinus, and Plato to Heraclitus – and with even more branches yet to be traced (p. xvii).
Polytheistic psychology
Thomas Moore says of James Hillman's teaching that he "portrays the psyche as inherently multiple".
 In Hillman's archetypal/polytheistic view, the psyche or soul has many 
directions and sources of meaning – and this can feel like an ongoing 
state of conflict – a struggle with one's daimones. According to Hillman, "polytheistic psychology can give sacred differentiation to our psychic turmoil.…" Hillman states that
The power of myth, its reality, resides precisely in its power to seize and influence psychic life. The Greeks knew this so well, and so they had no depth psychology and psychopathology such as we have. They had myths. And we have no myths – instead, depth psychology and psychopathology. Therefore... psychology shows myths in modern dress and myths show our depth psychology in ancient dress."
Hillman qualifies his many references to gods as differing from a literalistic approach saying that for him they are aides memoires, i.e. sounding boards employed "for echoing life today or as bass chords giving resonance to the little melodies of life."
 Hillman further insists that he does not view the pantheon of gods as a
 'master matrix' against which we should measure today and thereby decry
 modern loss of richness.
Psyche or soul
Hillman says he has been critical of the 20th century's psychologies (e.g. biological psychology, behaviorism, cognitive psychology) that have adopted a natural scientific philosophy and praxis.
 His main criticisms include that they are reductive, materialistic, and
 literal; they are psychologies without psyche, without soul. 
Accordingly, Hillman's oeuvre has been an attempt to restore psyche to 
its proper place in psychology. Hillman sees the soul at work in 
imagination, fantasy, myth and metaphor. He also sees soul revealed in psychopathology,
 in the symptoms of psychological disorders. Psyche-pathos-logos is the 
"speech of the suffering soul" or the soul's suffering of meaning. A 
great portion of Hillman's thought attempts to attend to the speech of 
the soul as it is revealed via images and fantasies. 
Hillman has his own definition of soul. Primarily, he notes that 
soul is not a "thing", not an entity. Nor is it something that is 
located "inside" a person. Rather, soul is "a perspective rather than a 
substance, a viewpoint towards things… (it is) reflective; it mediates 
events and makes differences…"(1975). Soul is not to be located in the 
brain or in the head, for example (where most modern psychologies place 
it), but human beings are in psyche. The world, in turn, is the anima mundi,
 or the world ensouled. Hillman often quotes a phrase coined by the 
Romantic poet John Keats: "call the world the vale of soul-making." 
Additionally, Hillman (1975) says he observes that soul:
refers to the deepening of events into experiences; second the significance of soul makes possible, whether in love or religious concern, derives from its special relationship with death. And third, by soul I mean the imaginative possibility in our natures the experiencing through reflective speculation, dream, image, fantasy—that mode which recognizes all realities as primarily symbolic or metaphorical.
The notion of soul as imaginative possibility, in relation to the 
archai or root metaphors, is what Hillman has termed the "poetic basis 
of mind".
Dream analysis
Because Hillman's archetypal psychology is concerned with fantasy, 
myth, and image, it is not surprising that dreams are considered to be 
significant in relation to soul and soul-making. Hillman does not 
believe that dreams are simply random residue or flotsam from waking 
life (as advanced by physiologists), but neither does he believe that 
dreams are compensatory for the struggles of waking life, or are 
invested with "secret" meanings of how one should live (à la Jung). 
Rather, "dreams tell us where we are, not what to do" (1979). Therefore,
 Hillman is against the 20th century traditional interpretive methods of
 dream analysis. Hillman's approach is phenomenological rather than 
analytic (which breaks the dream down into its constituent parts) and 
interpretive/hermeneutic (which may make a dream image "something other"
 than what it appears to be in the dream). His dictum with regard to 
dream content and process is "Stick with the image." 
Hillman  (1983) describes his position succinctly:
For instance, a black snake comes in a dream, a great big black snake, and you can spend a whole hour with this black snake talking about the devouring mother, talking about anxiety, talking about the repressed sexuality, talking about the natural mind, all those interpretive moves that people make, and what is left, what is vitally important, is what this snake is doing, this crawling huge black snake that's walking into your life…and the moment you've defined the snake, you've interpreted it, you've lost the snake, you've stopped it.… The task of analysis is to keep the snake there.…
The snake in the dream does not become something else: it is none of 
the things Hillman mentioned, and neither is it a penis, as Hillman says
 Freud might have maintained, nor the serpent from the Garden of Eden,
 as Hillman thinks Jung might have mentioned. It is not something 
someone can look up in a dream dictionary; its meaning has not been 
given in advance. Rather, the black snake is the black snake. 
Approaching the dream snake phenomenologically
 simply means describing the snake and attending to how the snake 
appears as a snake in the dream. It is a huge black snake, that is 
given. But are there other snakes in the dream? If so, is it bigger than
 the other snakes? Smaller? Is it a black snake among green snakes? Or 
is it alone? What is the setting, a desert or a rain forest?  Is the 
snake getting ready to feed? Shedding its skin? Sunning itself on a 
rock? All of these questions are elicited from the primary image of the 
snake in the dream, and as such can be rich material revealing the 
psychological life of the dreamer and the life of the psyche spoken 
through the dream.
The Soul's Code
Hillman's book, The Soul's Code: In Search of Character and Calling,
 outlines an "acorn theory of the soul." His theory states that each 
individual holds the potential for their unique possibilities inside 
themselves already, much as an acorn holds the pattern for an oak, 
invisible within itself. It argues against the parental fallacy whereby 
our parents are seen as crucial in determining who we are by supplying 
us with genetic material and behavioral patterns. Instead the book 
suggests for a reconnection with what is invisible within us, our daimon or soul
 or acorn and the acorn's calling to the wider world of nature. It 
argues against theories which attempt to map life into phases, 
suggesting that this is counter-productive and makes people feel like 
they are failing to live up to what is normal. This in turn produces a 
truncated, normalized society of soulless mediocrity where evil is not 
allowed but injustice is everywhere – a society that cannot tolerate 
eccentricity or the further reaches of life experiences but sees them as
 illnesses to be medicated out of existence.
Hillman diverges from Jung and his idea of the Self. Hillman sees
 Jung as too prescriptive and argues against the idea of life-maps by 
which to try to grow properly.
Instead, Hillman suggests a reappraisal of each individual's 
childhood and present life to try to find the individual's particular 
calling, the acorn of the soul. He has written that he is the one to 
help precipitate a re-souling of the world in the space between 
rationality and psychology. He replaces the notion of growing up, with 
the myth of growing down from the womb
 into a messy, confusing earthy world. Hillman rejects formal logic in 
favour of reference to case histories of well known people and considers
 his arguments to be in line with the  puer aeternus or eternal youth whose brief burning existence could be seen in the work of romantic poets like Keats and Byron and in recently deceased young rock stars like Jeff Buckley or Kurt Cobain. Hillman also rejects causality
 as a defining framework and suggests in its place a shifting form of 
fate whereby events are not inevitable but bound to be expressed in some
 way dependent on the character of the soul or acorn in question.
Psychopathology and therapy
Psychopathology
 is viewed as the psyche's independent ability to create morbidity, 
disorder, illness, abnormality and suffering in any part of its behavior
 and to imagine and experience life  through a deformed perspective.
Archetypal psychology follows the following procedures for therapy:
- Regular meetings
 - Face-to-face
 - The therapist chooses the location
 - A fee is charged
 
These procedures may be modified depending on the therapist and the 
client. In therapy both the therapist and client explore the client's  
habitual behavior, feelings, fantasies, dreams, memories, and ideas. The
 goal of therapy is the improvement of the client and termination of 
treatment. Goals are not stated for therapy.
