Brief Review of Metaphor Structure and Terminology

Metaphor is when you talk about one thing in terms of another.  Metaphor can be detected by close reading in context, by identifying words or phrases that are in some way incongruous if interpreted entirely literally, or by noting rhetorical turns that are not fully supported by literal statements.  Finding the lexical items – the words or phrases that are somehow incongruous –  may be the most concrete method.  A shorthand for labeling metaphors is Target is Source, where the Target is what you are talking about and the Source is the metaphoric domain.  Most often the Target is more abstract or subjective than the Source; talking about the Target in terms of the Source makes subjective experience seem more physical or concrete.
 
For example, in “We want to hire someone who will be a good team player,” the highlighted words suggest a metaphor where the Target is the selection of employees and the Source is recruiting players for a sport or game team: the shorthand would be Employees are Members of a Competitive Team.  The person saying this is presumed to have a subjective sense of how employees work best in the organization, but is choosing to represent this in the more concrete terms of competitive team membership.  This deliberate or accidental choice automatically sets the frame (competitive group activity with hierarchy and rules), direction or expectation (all members subordinate themselves and contribute their best towards winning), associations (ranking, prizes, penalties, goals, positions, etc.) and tends to eliminate or block from consciousness all the alternatives (e.g., cultivation as in a gardening metaphor, nurturing as in a family metaphor, protection as in a police or medical metaphor).
 
Just a note on the shorthand naming of metaphors.  The word “are” in the above example does not imply equivalence nor is it a statement of a logical proposition.  It is just a shorthand way to refer to the metaphor and the possible existence of a set of relationships between something being talked about (Target) and something quite different (Source), that is useful for understanding.

Conceptual Metaphor and Novel Metaphor

The examples so far have been of commonplace metaphors - that is, metaphors that we find in everyday usage, that are almost universally understood by those fluent in English, and which employ source domains (such as the human body, animals, plants and money transactions) that are very familiar to virtually everyone.  What about novel metaphors?  Metaphor research over decades, as well as more recent scholarly work on conceptual metaphor, has profited enormously from examining the novel use of metaphor by creative writers and poets.  Their metaphors operate by the same principles we have been discussing (as documented extensively by Lakoff and Turner, 1989; see below for a detailed discussion of these principles, with illustrations from Kafka).  The novel use of metaphor can simply consist of common metaphors arranged in ways that produce a striking effect. 

Let us look for creative or novel metaphors in a literary example.  We find unusual use of the Understanding is Seeing metaphor in these lines from the contemporary Irish poet, Eavan Boland (2001, p. 40), visiting the region in which her grandmother had lived: 

For once, I said,
I will face this landscape
and look at it as she was looked upon…

Here the target domain concerns how she is to understand her grandmother.  One source domain is looking with the eyes, seeing the landscape; so we have the metaphor Understanding is Seeing/Looking.  Also we have the target domain of accepting the grandmother and the source domain of physically turning so as to face something: Accepting is Facing.  Yet another metaphor in the same fragment also involves the target domain of understanding, but now in the sense of attitude, and the source domain of looking from a certain point of view, giving us the metaphor Attitude is Seeing from a Particular Viewing Position.  Another still is a metaphor based on the folk wisdom (including modern science) that living beings are naturally formed by the place they live, in this case Person is Place or Knowing a Person is Seeing a Person’s Habitat.

We can name these metaphors, map their correspondences and reveal their generic-level structure in the same manner as with any conceptual metaphor.  None of the metaphors is very unusual.  What is novel and creative here is the way they are superimposed to give a distinctive character to this particular target domain.  The poet expresses in compact form that she must accept her grandmother, the particular impacts of her locale, and what kind of person she was considered to be, all metaphorically expressed as seeing or viewing from and within a certain place. 

In everyday conversation, including what occurs during conflict resolution, therapy, or a learning situation, metaphoric meanings may not be so artfully combined.  Yet, one need not be a poet to take inspiration from how this combination of metaphors expresses a complex personal experience of knowing using the projections of several simple and common aspects of visually seeing.  Such inspiration can help at the point when a therapist, mediator, or teacher wishes to facilitate expanded and extended meaning in dialogue.

An Example from Oscar Wilde

Let us look for creative or novel metaphor in another literary example.  Consider this line from Oscar Wilde:  “How else but through a broken heart may the Spirit enter us?”  Here the target domain concerns how one obtains spirituality.  A source domain is the person as a sealed container, entry into which might occur through a break.  Another metaphor in the same sentence involves the target domain of desire or longing for spirituality and the source domain of emotional suffering by having your heart broken.  Another still is the personification of Spirit as a being that enters through openings. 

We can name such creative metaphors, map their correspondences and reveal their generic-level structure in the same manner as with conventional metaphors.  While the Spiritual Longing is Emotional Suffering metaphor is somewhat novel (for non-poets) the Person is Container metaphor is quite conventional (“I’ve had it up to here,” “A feeling of emptiness,” “Despite her love for him he never let her in”).  A distinguishing characteristic of novel metaphors is the unity obtained when several simple metaphors combine to form a unique understanding of the particular target domain.

In everyday conversation, including what occurs during conflict resolution, metaphoric meaning may not be as sophisticated and instead is more likely to include multiple metaphors expressed serially. 

 

Metaphors of Landscape Used to Express The Experiences of Thinking and Emotion

 

Reviewer Stephen Burt describes (in the New York Times Book Review, 15 Aug 2004) how a number of American poets use pastoral landscapes, imagined rural worlds, as metaphors for inner "worlds."  (Note that he and many others may avoid the word "metaphor" and instead simply refer to "symbols" that are said, in this case, to "encode claims about politics, religion, dead friends, living rivals or difficult loves.")

 

Some examples given that I have put in the metaphor shorthand:

·        Unresolved Emotion is Landscape of Mythical Monsters

·        Psychological Withdrawal is Melody Played on Slim Bone Flute

·        Frustration is Repeating Verse

·        Frustration is Drought, Winding Dry River Bed

·        Frustration is Stunted Growth

·        Remembering Former Loves is Taking Refuge in Walk From New York to Mexico

·        Truly Original Poetry is Field Where We Can Roam, Graze

 

Metaphors of Bodily Experience Used to Express Negative Emotion

 

Note the lexicon used to express emotional trauma (Emotional Trauma is Physical Trauma): being stabbed, jolted, attacked, slapped, shunned, dumped on, struck, ditched, isolated, crushed.

 
 

Metaphoric Interpretation of a Poem (10/16/2004)

The following poem is reproduced from a website.  I have highlighted words that would seem to indicate a metaphor.  In the column to the right are names of the metaphors I have found.  Below that are notes that describe how I think the metaphors work together.
 
 
Note on author:
In 1985, at the age of eighteen, Chris Abani was imprisoned after… the Nigerian government labeled his first novel a threat to national security. Upon release, Abani became active in a guerrilla theatre group that dared to perform plays in front of government building. This activity landed him in Kiri Kiri, a maximum-security prison. On his release, a year later, he returned to the university where he continued to write and study literature

Comments About the Metaphors Found

Assume that the title, Jacob’s Ladder, is the over-arching theme (Life is a Ladder).  We know something about Jacob’s Ladder from myth and metaphor that does not need to be stated – that it is a ladder each rung of which is a station or location, stretching between hell and heaven (Life and Death are Places).  It’s a rendition of the Great Chain of Being metaphor (that figures into a lot of poetry) and it contains both a journey aspect and an organizing principal.  The normative expectation (evoked by the metaphor) is to ascend to ever more perfect or higher states of being (that’s what we are hoping for as outcome).  So we are immediately told of these possibilities even though there is little reference in the poem to how the steps are organized.  Up to this point it seems we are to understand this poem, this person’s prison life and his release from prison, in terms of a journey metaphor. 

 

Interestingly, even after invoking Jacob’s ladder and the Great Chain of Being, etc, the journey metaphor is only minimally used.  The journey consists of only two steps – being in prison followed by the first moment of being released.  Although the poem makes no reference to it, our common sense of the journey metaphor says that most journeys have many steps, that there is a path, there may be a guide or a map, that each step along the way gives different vantage points, etc.  The deployment of the journey metaphor so over-simplified here simultaneously presents two possibilities:  One is that the prison makes your life so stark and basic that there are only two states – being in and getting out.  The second is that there might be so much more that the poet, for some reason, is not telling us and that we might want to ask about.

 

The idea of a container is both literal and figurative.  It is literal in that a prison is a box with walls, difficult to pass through.  It is figurative in that the psychological effect of being in prison is metaphorically understood as being in a place you can’t get out of (Prison is Hell/Death).  Not only are the literal walls there, but the psychological effects – what you are convinced of – become walls (Mental State is Physical State); this metaphor is implied from the beginning of the poem narrative, but lexically evident at the middle when the released prisoner is convinced he will be shot in the back).  The location of this container, we may assume, is at the bottom or near the bottom rung of Jacob’s ladder.

 

Death is metaphorically understood as such a place; also understood to be removed from normal life, enclosed, cold, smelly, colorless.  The normative expectation for someone in such a place is to get out if possible.  One might ask, so what is so informative about this?  But the point is that in using these metaphors to evoke the horror of the place so vividly, alternative interpretations tend to be blocked – e.g., the possible metaphor Being in Prison is a Journey is suppressed and we find ourselves not thinking about a possible figurative journey of traveling within the enclosed prison space.

 

A person is, in general, metaphorically understood as a valuable thing – something rare in the sense that a gem might be rare, even priceless (Prisoner is Treasure in a Container).  Such a thing lost in prison (death) is also rarely released (Release From Prison is Resurrection).  This might invoke other poetry about a diamond in the rough, gold at the bottom of the sea, a treasure in a ruin, etc.  The normative expectation is to cherish them, make good use of such things, not to waste, destroy or lose them.

 

When we understand a person metaphorically to be thing this entails our customary way of thinking about things.  What makes a thing valuable are its attributes.  The person’s possessions are his attributes (Person is What Person Possesses) and for the prisoner they have been taken away, except for what no one wants.  The metaphorical way of presenting the prisoner as a thing tends to suggest that he has lost all (Prisoner is Possessions No One Else Wants).  Then we see that the Prisoner is Target; Prisoner is Prey.  That is what the poem states.  But an ironic interpretation will come to mind – that he is not a thing, target or prey but instead a person climbing Jacob’s ladder, embodying human capabilities of qualitatively greater worth even than a rare, concealed treasure.  It is not clear if this ironic interpretation is intended.

 

The poem goes on to add to the description of prison and the prisoner’s experience with the metaphors of Prison is Freezer, Prisoner is Meat, Prisoner is Colorless, and Prisoner is Smelly Person.  These don’t add much to Prison is Hell/Death, so why include them?  Adding metaphors in this way usually rounds out a description or sets up interaction with other metaphors already there.  These later ones seem to redirect attention to the state of the prisoner’s body – congealed, smelly, armored, colorless, prepared to endure violence, but unable to absorb normal stimuli – and this sets us up to understand how, at the end of the poem, the warming of the sun and feeling everyday breezes (Normal Life is What is Carried by Air, Breeze), etc. can be painful and stinging (To Warm Up, Open Up is To Feel Pain).

 

Usefulness of the Metaphors

Searching for and finding metaphors in a poem is not the same as decoding a cipher – finding the rules that, when applied, explain exactly what was meant.  Instead it is a way to have a dialogue.  Identifying a metaphor is identifying a set of possible relationships that may exist between the poem’s text and various metaphoric domains that are evoked.  With knowledge of these metaphors the commentator can ask the poet, “You invoked such and such a metaphor and this metaphor sets up a particular inference structure.  Which of these inferences did you intend, and which not, and why?”

 

As does any poem, this one has non-metaphoric aspects such as a storyline with chronology and literal statements of what happened.  The metaphoric interpretation of this poem may do no more than perhaps deepen a little bit the interpretations one would make without special attention to the metaphors. 

 

But it can be fascinating to see how metaphors interact with literal aspects.  Although there are more than a dozen different metaphors, they do not clash with the literal parts but enhance them.  It would be interesting to explore how much of what the author experienced could actually be expressed literally.  Note that, among themselves, the metaphors in this poem are not “mixed metaphors” but coherent in their overall effect.  This is certainly not true in casual conversation or even in carefully constructed prose, and may not be in some poetry.  The interplay of several metaphors, and metaphors with literal statements, could reveal ambivalence, confusion or even deception.  Metaphors are deployed for rhetorical purposes, but cognitive science also points to the close correspondence between metaphor use and unconscious thinking.  So metaphor interpretation could be said to offer a window into what an author “really” thinks.

 

The title of the poem evokes a much more inclusive master metaphor than found within the poem, itself, and we may want to ask why.  The insights gained about the overall organization of the poem, what is said and what is left unsaid, add enjoyment and ought to provoke comment.  Perhaps most importantly metaphor awareness suggests several areas that have not been talked about in the poem explicitly but, by belonging to the structure of the metaphors, may or may not be intentionally implied.

 

Lakoff and Turner’s Novel Uses of Metaphor Using Illustrations From Kafka

 

Lakoff and Turner illustrate with various quotations from Shakespeare, Yeats and others, but I will attempt to demonstrate all of these within a short story from Kafka (1917/1997), “A Report for an Academy”.  The story is in the form of a lecture given by an ape – one that has lived among men for some years – to a scientific academy.  The allegory tells how the ape is wounded, then captured in the wild, caged, transported, tamed, trained and civilized, becoming an exemplary model of human decorum.  The reader can make sense of the ape-man’s account to the Academy of his experiences by metaphorically understanding the socialization process of humans using the very common metaphor of Man is an Animal, more particularly, Socialization of Man is Taming of an Animal.  Even though this metaphor is commonplace, Kafka’s creative use of it diverges from the ordinary and unlocks novel possibilities.  Here are the six ways:

Extending a Metaphor.  Only some of the correspondence mappings of a metaphor are normally used, but it can be extended by using additional ones that we might not normally consider.  For example, the dominant role of instinct in animals is routinely projected onto man: brutishness, assertion of primary needs, survival in the wild, and so on.  All of these are in this story but Kafka extends the metaphor beyond its conventional use by emphasizing another mapping we probably would not have thought of – that of wounding.  Although it may be common to capture wild animals by first wounding them, normally we may not think how early wounds to humans may shape their eventual socialization.  Similarly Kafka takes another uncommon mapping – the animal capacity for tranquility or quiescence – what he calls inner peace.  At the beginning of the ape-man’s captivity his keepers sometimes treated him gently and playfully and this helped him feel peaceful.  ”The peace I gained while among these people kept me from making any attempt to escape” (85) even though he most wanted a way out of captivity.

Elaborating a Metaphor.  Among the mappings of a metaphor that are used, normally some will not be described fully while others are.  Kafka describes the ape’s instinctive struggle to get food and to free himself.  He also describes the ape’s heightened attention to everything his captors did and how he began to imitate the captors’ actions (evoking the conventional idea of “monkey see, monkey do”).  Kafka elaborates on this mapping, describing how the ape took a schnapps bottle and drank exactly as the men did.  This elaboration is unexpected since so much of animal behavior is instinctive need-fulfillment.  The imitative drinking actually sickened him, but he “aped” as he “took the schnapps bottle that had accidentally been left by my cage, uncorked it… put it to my mouth and… like an expert drinker, with rolling eyes, a gurgling throat, really and truly drank the whole bottle…” (p 90).  The men cheer.  The imitative ape behavior is elaborated into the special case of a learning experience and bonding ritual that opens up possibilities for the ape.

Questioning a Metaphor.  Metaphors are never perfectly apt.  Fully mapped, there will always be some aspects of the source domain that don’t accurately correspond to the target.  But this will not be a shortcoming if such discrepancies are used to highlight important characteristics of the target domain, to break thought patterns, or suggest contrary mappings.  In this story Kafka maintains the Man is an Animal metaphor as an allegorical story line throughout.   However he puts the aptness of this metaphor in question when the ape transcends imitation, acting, and his training as a stage performer.  “Through an effort that has never since been repeated in the world I attained the education of an average European.”  This, the ape says, “…helped me out of my cage and created a special way out for me, the human way out.” (p 92).  The ape has benefited from super-human achievements.  Now is it man or ape who is more highly evolved?

Composing Metaphors.  Other metaphors are also used within the story.  Certain ones combine with the Man is an Animal metaphor to give the story its unique structure.  Journey; variety theater;  The ape moves from being a captive, to being trained, to being a performer, and finally becomes a star performer with all the worldly benefits that accrue.  From the start when he is shot and captured he is on a journey.  His destination is not freedom, but simply “a way out.”  He passes through several arduous stages along the way, but is motivated to do what is necessary to keep going.  The ape-man’s journey metaphor is elaborated with his “special way out” in place of a more conventional destination.  Composing the metaphors Man is an Animal with Life is a Journey combines the planfulness of taking a journey with the single-mindedness of animal instinct – a distinctive structure giving rise to divergent interpretation.  Later, when the ape-man becomes a star of the variety theater, Life is Performing on the Stage composes the imitative character of an ape with the purposefulness of a journey, depicting almost superhuman accomplishment in a subhuman creature.

Personification Metaphors.  This is a highly composed form of metaphor combination – taking attributes, events and relationships observed in the target domain and representing them metaphorically as those of humans.  By so doing, even something as impassive as a rock can take on human emotions, motivation, or perception, allowing us to think about it as we might regard ourselves.  This permits the creation and exploration of rich and unexpected ideas and is a major divergent influence of metaphors.  However, Kafka evidently had plenty of creative scope already at hand and, in the story considered here, I have found no personification in which lesser beings, objects or ideas are metaphorically understood as people or, for that matter, as animals.  (The thematic allegory of the story, in fact, uses an animal metaphor in reverse, understanding people as apes.)  Weak forms of personification (that might be called animation metaphors) are ubiquitous and include the attribution of change, power and influence to inanimate, powerless and often unmoving objects or abstractions.  Kafka animates things and concepts such as when “promises appear belatedly” and an “accumulation of observations that forced me in the direction…” (p 86) or when the ape-man considers escape from his own cage only to be put in that of his fellow captives from the jungle, where he might feel the embrace of boa constrictors.  Such animation metaphors lack the complete composition of personhood that Lakoff and Turner illustrate, such as “The world is awake tonight./ It is lying on its back with its eyes open” (1989: 72). 

Generic Structure of Metaphors.  Many conceptual metaphors have within them basic metaphor structures that tie them together with other metaphors to allow more complex compositions and the potential for marked divergence in meaning.  Two such generic metaphors that have been extensively studied are the Great Chain of Being (giving metaphoric understanding of entities, objects, things, and beings) and Event Structure (through which we metaphorically understand change, events, and causation) (Kövecses 200 ; Lakoff and Turner 1989; Lakoff and Johnson 1999).

Great Chain of Being Metaphor.  The hierarchic organization of existence that we understand from folk wisdom and religious doctrine and that is recapitulated in countless ideas and assumptions we use daily is called the Great Chain of Being.  It is a set of philosophical principals giving rise to the kind of parallelism we observe, for example, between mammal and reptile physiology, between a river and a blood vessel, between the mind and the soul, or between a computer and a brain.  Traditional versions of the Great Chain of Being range linearly along a continuum of forms from the simplest things, on up to deities, and each form shares at least one attribute with its nearest neighbors.  The order is hierarchic such that forms are more complex, capable and perfect as you move towards the top.  Wilber (2001 [Wilber, K. (2001) Quantum Questions, Boston: Shambhala, p.14]) represents the Great Chain metaphor in concentric circles, with physical matter at the center, ranging through life, mind, soul to spirit in the outer-most circle.  While a fully rich understanding may only be achieved by dedicated scholars or saints, virtually everyone acquires folk knowledge of the essential tenets of the Great Chain of Being from an early age.  Lakoff and Turner (1989:166) assert that the Chain of Being metaphor "is largely unconscious and so fundamental to our understanding that we barely notice it." 

Note the parallelism or resonance seen to exist between all such levels (e.g., moral functions are analogous to cognitive functions but include the higher power to organize community, global, or cosmic concerns).  The Chain of Being metaphor evokes the naturally occurring essences of things and beings that give rise to naturally occurring outcomes.  Unlike the Event Structure metaphor considered below, the Great Chain of Being does not involve motion nor is it conceived in terms of a mechanism.  For example, the essential aspects of an animal give rise to that animal's instincts and instinctual behaviors, or the power and authority of a magician give rise to miracles; in such examples the entity (thing, animal, human) is being more truly itself.

With regard to personification, animal and animation metaphors, mentioned earlier, the "lower order" forms in the Chain are useful because we have detailed familiarity with, for example, how animals naturally mate, seek food, etc. or how pieces slide into place, objects have insides and outsides or structures are built.  So, comprehending complexities of humans in terms of simpler characteristics of things or of other beings in nature serves to understand higher in terms of lower, complex in terms of simpler, reason in terms of biology or physics, etc.  However, when it comes to understanding higher processes in animals we may readily use subjective experience in oneself in an anthropocentric personification metaphor (e.g., the cat chooses to be independent), or to understand people we may invoke angels or the cosmos as metaphoric source domains.

Lakoff and Turner (1989) tie understanding of the Chain of Being to the Generic is Specific metaphor.  In Kafka’s tale mankind’s generic socialization and development are metaphorically understood in terms of a specific ape-man’s allegory.   Kövecses (2002) describes an “extended” Chain of Being that has gradations integrated within each level such that knowledge about the order of things and the part-whole structure reveals levels and parallel patterns that we might regard as analogous.  For example, physical matter can be simply substance, or can be differentiated into parts that form a whole, and eventually (at a higher level) into life forms.  Life can be differentiated into metabolism, reproduction, mobility and self-propulsion, introspection, cognitive function, moral function, etc. 

The ape-man’s passage through several phases of his transformation – captivity, taming, imitating, and stage acting – replicates a generic set of part-whole relationships that allow us to make sense of the story.  It works because we are so familiar, not just with animal and human development, but with how humans and animals are the same in certain respects.  We don’t normally think of human development as finding a way out of a cage, nor do we generally understand how one learns to act creatively on stage in terms of a primate’s simple imitation to please his captors.  Yet this metaphoric allegory regarding higher human function works in terms of lower primate capacities and needs no special explanation.

Kafka uses the Chain of Being metaphor structure also to project understanding of a kind of super-human capacity for discipline that the ape-man has more so than a human, which achieves a liberation for the ape-man cast in terms of human satisfaction… we understand human capacities in terms of animal ones, and animal capacities in terms of human ones…

 

John Wollard’s Illustration of Metaphor in Poetry

 

John Woollard
May 2001

Metaphor is used in invoke thought and contemplation of an idea. In this short poem there is an implied connection between the concept mountain and the concept motherhood. 

The poetry is considered to have alliterative depth because the words play upon the metaphor and twist the mind's consideration of the concept of motherhood through reference to the mountain state. The mountain is: old (grey haired) and getting older; protecting (creates an enclosed valley climate); creator (the rich alluvial soil is created from the erosion of the mountain side); maid (the mountain serves the valley with water from the spring thaws and relief rain); wrinkled (ever deepening lines in the surface of the mountainside); her children (the foot hills created by the erosion of the mountain)… 

A metaphor gives dimension to the one dimensional structure of speech, poetry and prose. Because speech, poetry and descriptive prose is a fleeting temporal linear means of communication and because the human is limited by the amount of information that can be stored and processed in the active mind at any one time, speakers and writers always benefit from using tools that bring information into active memory for re-coding it for communication or encoding it for long term memory.
