noun
verb
symbol, in the simplest sense, anything that stands for or represents something else beyond it—usually an idea conventionally associated with it. Objects like flags and crosses can function symbolically; and words are also symbols. In the semiotics of C. S. Peirce, the term denotes a kind of sign that has no natural or resembling connection with its referent, only a conventional one: this is the case with words. In literary usage, however, a symbol is a specially evocative kind of image (see imagery); that is, a word or phrase referring to a concrete object, scene, or action which also has some further significance associated with it: roses, mountains, birds, and voyages have all been used as common literary symbols. A symbol differs from a metaphor in that its application is left open as an unstated suggestion: thus in the sentence She was a tower of strength, the metaphor ties a concrete image (the ‘vehicle’: tower) to an identifiable abstract quality (the tenor: strength). Similarly, in the systematically extended metaphoric parallels of allegory, the images represent specific meanings: at the beginning of Langland's allegorical poem Piers Plowman (c.1380), the tower seen by the dreamer is clearly identified with the quality of Truth, and it has no independent status apart from this function. But the symbolic tower in Robert Browning's poem ‘ “Childe Roland to the Dark Tower Came” ’ (1855), or that in W. B. Yeat's collection of poems The Tower (1928), remains mysteriously indeterminate in its possible meanings. It is therefore usually too simple to say that a literary symbol ‘stands for’ some idea as if it were just a convenient substitute for a fixed meaning; it is usually a substantial image in its own right, around which further significances may gather according to differing interpretations. The term symbolism refers to the use of symbols, or to a set of related symbols; however, it is also the name given to an important movement in late 19th‐century and early 20th‐century poetry: for this sense, see Symbolists. One of the important features of Romanticism and succeeding phases of Western literature was a much more pronounced reliance upon enigmatic symbolism in both poetry and prose fiction, sometimes involving obscure private codes of meaning, as in the poetry of Blake or Yeats. A well‐known early example of this is the albatross in Coleridge's ‘The Rime of the Ancient Mariner’ (1798). Many novelists—notably Herman Melville and D. H. Lawrence—have used symbolic methods: in Melville's Moby‐Dick (1851) the White Whale (and indeed almost every object and character in the book) becomes a focus for many different suggested meanings. Melville's extravagant symbolism was encouraged partly by the importance which American Transcendentalism gave to symbolic interpretation of the world.
Verb: symbolize.
See also motif.1. Representation of something, e.g. sacred, such as the elements of the Eucharist.
2. Familiar object used mnemonically to represent acts, persons, ideas, or anything, e.g. the Cross for Christianity, the means by which a Saint was martyred (attribute) (such as the gridiron for St Lawrence, the flaying-knife for St Bartholomew, a dove for the Holy Spirit).
3. Something representing what it is, unlike an allegory (which is a description of a subject under the guise of some other subject of aptly suggestive resemblance: it therefore represents something it itself is not).

One item used to stand for or represent another—as in the case of a flag which symbolizes a nation.
Modern science has in its development profited from the conciseness provided by many symbols. In chemical symbols, for example, each element is represented by one or two letters (e.g., carbon, C; zinc, Zn). Some symbols are derived from non-English names, e.g., Ag for silver (Latin argentum). A chemical formula is written in chemical symbols.
In art a distinction of terms is introduced that modifies the term symbol. Although the drawings at Altamira are considered symbolic in one sense (i.e., a drawn reindeer is the symbol for a live reindeer), they are said not to be symbols in another more common sense, since they are partially iconic. If the artist had merely drawn two horns to represent an entire reindeer, the two horns might be said to be a symbol for a reindeer. Such symbolism is all-pervasive in every kind of art, especially because it lends itself to rapid, comprehensive, and compact use.
Religious symbolism is best known in its more ancient form from the discoveries of archaeologists; this is especially important in the study of Egyptian religion, in which the symbol of the god often appeared more frequently than the likeness of the god himself. Greek religion, on the contrary, seemed to eliminate symbols of gods in favor of actual images. In Judaism and Christianity religious symbolism is important, notably in the prophetic passages in the Bible and in the uses of public worship (see, for example, candle; incense; liturgy; sacrament; see also iconography).
Modern patriotism, particularly in the United States, has found a revered symbol in the flag, which began, like all heraldry, as a means of recognition. Trade symbols are sometimes quite widespread; although the wooden Indian signifying the tobacco shop has disappeared, barber poles are still common. The investigations of Sir James Frazer in comparative religion and those of Sigmund Freud in psychology, extreme though they may be, have shown that human beings tend always to use a wide symbolism, even in thinking itself, to cover ideas they avoid out of fear, propriety, or some other motive.
From a psychoanalytic perspective, the symbol refers to all indirect and figurative representations of unconscious desire (symptoms, dreams, slips of the tongue, parapraxes, etc.). This conception of the unconscious symbol depends on a relation of general substitution where one thing takes the place of another; but unlike the term's conventional meaning, defined by the conjunction between the symbol and what is symbolized, the unconscious symbol is defined by a disjunction between symbol and symbolized.
Freud clarified this conception of the symbol following the "Project for a Scientific Psychology" (1950c [1895]), describing it as a mnemic symbol subsequent to his research into hysterical symptoms. In the case of a "standard" symbol, the connection between the symbol and what is symbolized remains, as in the example that Freud gives of the knight who fights for his lady's glove but who knows full well that the glove owes its importance to her. In this synecdoche of part for whole the conjunction of meaning is clear. With hysteria however, it is the loss of the connection between the symbol and what is symbolized that is noteworthy: "The hysteric, who weeps at A, is quite unaware that he is doing so on account of the association A-B, and B itself plays no part at all in his psychical life. The symbol has in this case taken the place of the thing entirely" (1950c, p. 349).
As a result of this disjunction of meaning, the affect that was bound to what is symbolized attaches itself to the symbol. In both instances the substitution assumes a similarity between the symbol and what is symbolized (A/B), and thus emerges the tension at the very heart of symbolic substitution between a nonsensical literal interpretation and a symbolic interpretation that supports a surplus of meaning because of the very denial or negation [négation] precluding the pure and simple assimilation of the two terms in question. In the case of the hysterical symbol, it is the impossibility of invoking denial that would explain the symptom's apparent absurdity.
What might appear here as a simple relation of substitution between two terms —the symbol and what is symbolized—allows, in fact, for an interpretation where meaning might attributed according to context. The symbol's abundance derives from its polysemy, but only reference to a regulated system of interpretation can lend precision to the symbol, hence the requirement to define the system and determine what it is that permits this regulation.
Freud hesitated between two rules of interpretation. Either it depends on individual context—specifically, a person's individual associations, which permit them to discover hidden meaning, as in the hysterical symptom or in dreams—or on collective context—specifically, a work of transindividual culture that clarifies meaning, as in "symbolic dream-interpreting" (1900a, p. 97). On the subject of the dream, he depicted sexual symbols that did not arouse associations for the dreamer but that the analysis would supply by referring to the symbolism of collective compositions (myths, tales, proverbs, songs, etc.); this enabled him to rediscover the correlation between the manifest and latent symbol. This obscure and concealed comparability appeared to be based on a relationship of equivalence (a tree for the male sex organs, a cave for the female sex organs), but also occasionally on a relationship of proximity (nudity symbolized by clothes and uniforms).
If symbols are multiple, the field of what is symbolized is highly limited, relating ultimately to the domain of sexual instinct. The theory of a predetermined and stereotyped sexual symbolic, in the service of an oneiric representability, corresponds with Freud's wish to contest Jung's theory of symbolism, whose conception of the "libido-symbol" ends up denying the importance of the sexual instinct in psychic behavior. Ernest Jones's key paper, "The Theory of Symbolism" (1916), seeks moreover to reinforce the Freudian theory of "symbolic dream-interpretation"; for Jones all true symbolism is the substitute for repressed drives/instincts: "Only that which is repressed is symbolized and only that which is repressed requires symbolization."
It is a question then of finding a rule of interpretation that can substantiate the discovery of the unconscious. To back up his theory Freud adopted the linguist Hans Sperber's theory of a primitive language [langue] parallel to the primitive language system [langage] of sexuality in which all symbolic connections would appear as traces and relics: "That which today is linked symbolically was in all probability formerly linked conceptually and linguistically." Freud is thus compelled to set out from a real anteriority, in a proximate association, or identity even, that belongs, through a similar association, to language and to a process of symbolization that is inseparable from the work of instinct.
Thus, the theory of the symbolic designates more of a structural demand than a clinical truth. In clinical terms, Freud always mistrusted instant symbolic interpretations and preferred to rely on individual associations that allowed him to uncover a linguistic usage that would justify the use of a symbolic representation.
Freud's theory of the symbol cannot therefore be separated from a conception of symbolization, which bears out the fact that the psychoanalytic approach is more a tripartite theory of interpretation, where it is necessary to consider the subject who symbolizes, than a theory of translation seeking to proceed via the simple substitution of one term for another. Freud's uncertainty demonstrates the difficulty of constructing a theory of the symbol while making allowances for the symbol both as a motivated sign (the symbol for Ferdinand de Saussure, corresponding to a natural analogy between symbol and symbolized) and as an arbitrary sign (the symbol for Charles Sanders Pierce, corresponding to the standard rule governing the signifier and signified, in other words to the arbitrary linguistic sign).
What is problematic with this theory of the symbolic is the conception of symbolization as a failure of sublimation rather than as its accomplishment. This opposition marks a return in too radical a fashion to the opposition between a symbolism of the unconscious and a symbolism of language. Post-Freudian theorists have sought to reconcile these different aspects of the symbol, whether through a semantic perspective associated with the image, as in the case of Melanie Klein and post-Kleinian theorists, or through a syntactic approach associated with language, as in the case of Jacques Lacan. It is a question in both cases of reviving the Freudian intuition of the symbol as the result of a process of symbolization. To Klein's interpretation of the imaginary, which retains a certain psychological realism, Lacan opposed reference to the symbolic order that represents an intellectualization of the unconscious.
The approach to symbolization as a process presupposes the preservation of that which Freud, rather awkwardly, wished always to have prevail: namely, the necessity for a dualism, for the articulation of a viable distinction between the symbolism of the image and the symbolism of language. The truth of Freudian empiricism in the theory of primitive language, like the original proximity of the symbol, is no doubt to mark the importance of this fundamental proximity of the psyche with the body as the juncture between representation and affect, between meaning and primitive animism, characteristic of the hallucinatory satisfaction of desire.

An object or name that stands for something else, especially a material thing that stands for something that is not material. The bald eagle is a symbol of the United States of America. The cross is a symbol of Christianity. The Star of David is a symbol of Judaism.
— Willard V. Quine
An image transferred by something that stands for or represents something else, like flag for country, or autumn for maturity. Symbols can transfer the ideas embodied in the image without stating them.
n.
Something that is supposed to typify or stand for something else. Many symbols are mere "survivals" -- things which having no longer any utility continue to exist because we have inherited the tendency to make them; as funereal urns carved on memorial monuments. They were once real urns holding the ashes of the dead. We cannot stop making them, but we can give them a name that conceals our helplessness.
The garden is a metaphor for life, and gardening is a symbol of the spiritual path.

Quotes:
"The symbolic view of things is a consequence of long absorption in images. Is sign language the real language of Paradise?"
- Hugo Ball
"The whole visible universe is but a storehouse of images and signs to which the imagination will give a relative place and value; it is a sort of pasture which the imagination must digest and transform."
- Charles Baudelaire
"The society of merchants can be defined as a society in which things disappear in favor of signs. When a ruling class measures its fortunes, not by the acre of land or the ingot of gold, but by the number of figures corresponding ideally to a certain number of exchange operations, it thereby condemns itself to setting a certain kind of humbug at the center of its experience and its universe. A society founded on signs is, in its essence, an artificial society in which man's carnal truth is handled as something artificial."
- Albert Camus
"In a symbol there is concealment and yet revelation: here therefore, by silence and by speech acting together, comes a double significance. In the symbol proper, what we can call a symbol, there is ever, more or less distinctly and directly, some embodiment and revelation of the Infinite; the Infinite is made to blend itself with the Finite, to stand visible, and as it were, attainable there. By symbols, accordingly, is man guided and commanded, made happy, made wretched."
- Thomas Carlyle
"If you are to reach masses of people in this world, you must do it by a sign language. Whether your vehicle be commerce, literature, or politics, you can do nothing but raise signals, and make motions to the people."
- John Jay Chapman
"All abstract sciences are nothing but the study of relations between signs."
- Denis Diderot

Something that represents or suggests something else. Symbols often take the form of words, visual images, or gestures that are used to convey ideas and beliefs. All human cultures use symbols to express the underlying structure of their social systems, to represent ideal cultural characteristics, such as beauty, and to ensure that the culture is passed on to new generations. Symbolic relationships are learned rather than biologically or naturally determined, and each culture has its own symbols.

A symbol is something that represents an idea, a process, or a physical entity. The purpose of a symbol is to communicate meaning. For example, a red octagon may be a symbol for "STOP". On a map, a picture of a tent might represent a campsite. Numerals are symbols for numbers. Personal names are symbols representing individuals. A red rose symbolizes love and compassion.
In cartography, an organized collection of symbols forms a legend, or key.

The word derives from the Greek symbolon meaning token or watchword. It is an amalgam of syn- "together" + bole "a throwing, a casting, the stroke of a missile, bolt, beam." The sense evolution in Greek is from "throwing things together" to "contrasting" to "comparing" to "token used in comparisons to determine if something is genuine." Hence, "outward sign" of something. The meaning "something which stands for something else" was first recorded 1590, in Edmund Spenser's Faerie Queene.[1]
Swiss psychoanalyst Carl Jung, who studied archetypes, proposed an alternative definition of symbol, distinguishing it from the term sign. In Jung's view, a sign stands for something known, as a word stands for its referent. He contrasted this with symbol, which he used to stand for something that is unknown and that cannot be made clear or precise. An example of a symbol in this sense is Christ as a symbol of the archetype called self.[2] For example, written languages are composed of a variety of different symbols that create words. Through these written words, humans communicate with each other. Kenneth Burke described Homo sapiens as a "symbol-using, symbol making, and symbol misusing animal" to indicate that a person creates symbols in her or his life as well as misuses them. One example he uses to indicate his meaning behind symbol misuse is the story of a man who, when told a particular food item was whale blubber, could barely keep from throwing it up. Later, his friend discovered it was actually just a dumpling. But the man's reaction was a direct consequence of the symbol of "blubber" representing something inedible in his mind. In addition, the symbol of "blubber" for the man was created by him through various kinds of learning. Burke emphasizes that humans gain this type of learning that helps us create symbols by seeing various print sources, our life experiences, and symbols about the past.
Burke goes on to describe symbols as also being derived from Sigmund Freud's work on condensation and displacement further stating that they are not just relevant to the theory of dreams, but also to "normal symbol systems". He says they are related through "substitution" where one word, phrase, or symbol is substituted for another in order to change the meaning. In other words, if a person does not understand a certain word or phrase, another person may substitute a synonym or symbol in order to get the meaning of the original word or phrase across. However, when faced with that new way of interpreting a specific symbol, a person may change their already formed ideas to incorporate the new information based on how the symbol is expressed to the person.
Jean Dalby Clift says that people not only add their own interpretations to symbols, they also create personal symbols that represent their own understanding of their lives: what she calls "core images" of the person. She argues that symbolic work with these personal symbols or core images can be as useful as working with dream symbols in psychoanalysis or counseling.[3]

Paul Tillich argued that while signs are invented and forgotten, symbols are born and die. There are therefore dead and living symbols. A living symbol can reveal hidden levels of meaning, and transcendent or religious realities to an individual. For Tillich, a symbol always "points beyond itself" to something that is unquantifiable and mysterious. This is the symbol's "depth dimension". Symbols are complex and their meanings can evolve as the individual or culture evolves. When a symbol loses its meaning and power for an individual or culture, it becomes a dead symbol. The Greek Gods might be an example of dead symbols that were once living for the ancient Greeks but whose meaning and power is now gone.
When a symbol becomes identified with the deeper reality to which it refers, it becomes idolatrous as the "symbol is taken for reality." Here, the symbol itself is substituted for the deeper meaning it intends to convey. The unique nature of the symbol is that it gives access to deeper layers of reality which are otherwise inaccessible.

A symbol's meaning may be modified by various factors including popular usage, history, and contextual intent.
This history of a symbol is one of many factors in determining a particular symbol's apparent meaning. Consequently, symbols with emotive power carry problems analogous to false etymologies.
The context of a symbol may change its meaning. Similar five–pointed stars might signify a law enforcement officer or a member of the armed services, depending the uniform.
