Emerging in the late fifties in
Structuralism is in the first place a method of critical investigation, but at a deeper level of analysis it appears not only as a method, but also as a “general tendency of thought”, or an ideology, whose prerequisite is to “value structures at the expense of substances”, to use Gérard Genette’s words.  Indeed, the ambition of the structuralist proponents (similar to that of archeologists or geologists) was to dig out the codes, systems and structures which governed any cultural activity and its products. Language and all other discursive and symbolic systems is constituted from the immanent relations among their component elements, and the “grammar” of these relations is liable to being discovered and formulated. If meaning exists, it is made possible by the underlying system of distinctions and conventions, Jonathan Culler opined in Structuralist Poetics. “Wherever there are two posts one can kick a ball between them but one can score a goal only within a certain institutional framework”, he explains. 
Perception, thought, cultural products are constructed and not natural. STRUCTURE  (which is related to the concepts of value and system) is the basic principle of construction and it becomes the main object of investigation. The structuralist approach is anti-humanist par excellence, as the human subject is no more the source of, and the main point of reference for cultural enterprises: it is removed from the focus of inquiry, so that the system can be isolated and analyzed. Within this approach, structure is an abstract category, a center, or point of origin (e.g. the geometry of perspective in the Renaissance painting, the arrangement of the sequences in folk narratives, or even the array of garments for a ceremonial occasion), and it supersedes other centers, such as history or the human person. Every component element has a relational meaning and value, because it exists as a result of an option: therefore the meaning can be found out by defining the place of the element within the general structure, rather than by relating it to the world outside that structure. If the meaning resides exclusively in the types of relationships among the component parts (the elements being arranged mostly as binary oppositions), then the structuralist view of structure differs substantially from the previous ones, including Cleanth Brooks’s definition, which included interpretations and evaluations, that is to say the work’s moral and cultural significance.
How could we explain this obsession with such a theoretical notion as structure? The answer may lie, in our opinion, in the almost mystical fascination which abstract configurations have always aroused in the human mind, with their challengingly symmetrical, geometric complexity.
The term “structuralism” was first used by Roman Jakobson in 1929:
Were we to comprise the leading idea of present-day science in its most various manifestations, we could hardly find a more appropriate designation than structuralism. Any set of phenomena examined by contemporary science is treated not as a mechanical agglomeration but as a structural whole, and the basic task is to reveal the inner ... laws of the system. /Emphasis added/
However, the remote roots of the structuralist movement, beyond the schools of Russian Formalism, the
It is easy ... to confuse the system with its manifestations, to think of English as the set of English utterances. But to learn English is not to memorize a set of utterances; it is to master a system of rules and norms which make it possible to produce and understand utterances... The linguist’s task is not to study utterances for their own sake; they are of interest to him only in so far as they provide evidence about the nature of the underlying system, the English language.(SP 2)
When one deals with physical events, says Culler, laws can be formulated which are nothing other than “direct summaries of behavior”, but when social and cultural phenomena are studied, behavior often deviates considerably from the norm, a distance appears between them, and for the researcher “that gap is a space of potential meaning”. (SP 3)
According to Saussure, language, as a self-authenticated system, exists outside the individual, who cannot create or change it, and also outside the world of things. Therefore signification takes place not through the interaction of words and things, but through the association of the sound images (signifiers) with concepts (signifieds). And signifiers come into being through the relationships with other signifiers: these relationships can occur on the paradigmatic axis (the vertical column of possible substitute elements to be used at any given place) or on the syntagmatic axis (the series of individual terms combined in a contiguous chain to make up a meaningful utterance). Signifiers are arranged in pairs of binary oppositions, as Nikolay Troubetzkoy,  a leading member of the Prague Linguistic Circle, observed later (for instance voiced/ non-voiced, nasalized/ non-nasalized, tense/ lax phonemes).
Saussure realized that the study of sign-systems initiated by him led to the creation of a new discipline, which he called semiology: in the following decades of the 20th century it developed as a parallel discipline, so closely connected with structuralism that sometimes the two terms were used interchangeably. In the second part of this chapter we will deal in a detailed manner with semiology (or “semiotics”) and with its implication for literary studies.
In the activity of Roman Jakobson, one of the fathers of structuralism, linguistics and semiotics merged with literary studies. His career may be said to impersonate both the pre-history and the history of this trend of thought in the 20th century.
The position he adopted concerning the object of literary studies while he was a member of the
Jakobson’s 1958 manifesto “Linguistics and Poetics” paved the way for further linguistic-semiotic analyses of texts, establishing the basic terms of investigation. He described six factors contributing to verbal communication: the addresser (or encoder) and the addressee (or decoder); the message; the code (usually a language); the context (or referent); the contact (or medium: live speech, writing, and so on). There is a function of communication corresponding to each of these, respectively the emotive, conative, poetic, metalingual, referential, phatic functions. It is very rarely that only one function is fulfilled: in reality there is a diversity of them, one usually being predominant. On the other hand the poetic function, for instance, does not appear only in poetry, but also in many other types of verbal messages, including advertisements, and so forth. We will refer in detail to the poetic function later in this chapter.
Relying on Saussure’s description of the syntagmatic and paradigmatic axes, Jakobson formulated a new theory based on the opposition between SELECTION and COMBINATION in the acquisition and the use of language. In “Two Aspects of Language”, a study combining linguistics and psychopathology, first published in 1956, he analyzed the manifestations of aphasic disturbance with mental patients: each form of aphasia consists in some impairment of the faculty for either selection and substitution or for combination and contexture.  The relation of similarity (typical of metaphor) is suppressed in one case, while that of contiguity (typical of metonymy) is absent in the other one. So Jakobson implies that the two linguistic operations can be understood in terms of the corresponding rhetorical figures.
The alternation METAPHOR / METONYMY can be considered to underlie all forms of verbal art, and not only these, Jakobson insists. In Russian lyrical songs the former predominates, while in heroic epics it is the other one which does. This opposition can be extended to describe various literary schools: romanticism and symbolism are dominated by metaphorical patterns, while the realistic trend is mainly metonymic:

 “For the most part these critics share the Socratic penchant, what Nietzsche defined as ‘the unshakable faith that thought, using the thread of logic, can penetrate the deepest abysses of being’. ... The inheritors ... of the Socratic faith would believe in the possibility of a structuralist-inspired criticism as a rational and rationalizable activity, with agreed-upon rules of procedure, given facts, and measurable results.” Miller distinguishes between these critics and those coming after them, such as Jacques Derrida and Paul de Man, who could be described as “Apollonian/ Dionysian, tragic, or uncanny”.(J. H. Miller, 336; 335).
