Post-Structuralism

Post-structuralism means to go beyond the structuralism of theories that imply a rigid inner logic to relationships that describe any aspect of social reality, whether in language (Ferdinand de Saussure or, more recently, Noam Chomsky) or in economics (orthodox Marxism, neoclassicalism, or Keynesianism).

Post-structuralism recognizes the power of discourse to shape reality (both perceptions of reality and the concrete reality that is perceived). Discourse (theory) can produce sight of fictive objects, such as race (as in white race), or deny sight of real social relationships/objects, such as class (as in feudal class relationships).

Post-structuralism emerged in France during the 1960s as an antinomian movement critiquing structuralism. The period was marked by political anxiety, as students and workers alike rebelled against the state in May 1968, nearly causing the downfall of the French government. At the same time, however, the support of the French Communist Party (FCP) for the oppressive policies of the USSR contributed to popular disillusionment with orthodox Marxism. As a result, there was increased interest in alternative radical philosophies, including feminism, western Marxism, anarchism, phenomenology, and nihilism. These disparate perspectives, which Michel Foucault later labeled "subjugated knowledges," were all linked by being critical of dominant Western philosophy and culture. Post-structuralism offered a means of justifying these criticisms, by exposing the underlying assumptions of many Western norms.

The movement is closely related to postmodernism. As with structuralism, anti-humanism, as a rejection of the enlightenment subject, is often a central tenet. Existential phenomenology is a significant influence; one commentator has argued that post-structuralists might just as accurately be called "post-phenomenologists."
Two key figures in the early post-structuralist movement were Jacques Derrida and Roland Barthes. In a 1966 lecture "Structure, Sign and Play in the Discourse of the Human Science", Jacques Derrida presented a thesis on an apparent rupture in intellectual life. Derrida interpreted this event as a "decentering" of the former intellectual cosmos. Instead of progress or divergence from an identified centre, Derrida described this "event" as a kind of "play."

In a 1976 lecture series, Foucault briefly summarized the general impetus of the post-structuralist movement:
“For the last ten or fifteen years, the immense and proliferating criticizability of things, institutions, practices, and discourses; a sort of general feeling that the ground was crumbling beneath our feet, especially in places where it seemed most familiar, most solid, and closest to us, to our bodies, to our everyday gestures. But alongside this crumbling and the astonishing efficacy of discontinuous, particular, and local critiques, the facts were also revealing something... beneath this whole thematic, through it and even within it, we have seen what might be called the insurrection of subjugated knowledges”. (Foucault, Society Must be Defended, 7th January 1976, tr. David Macey)

Post-structuralist philosophers like Derrida and Foucault did not form a self-conscious group, but each responded to the traditions of phenomenology and structuralism. Phenomenology, often associated with two German philosophers Edmund Husserl and Martin Heidegger, rejected previous systems of knowledge and attempted to examine life "just as it appears" (as phenomena).[9] Both movements rejected the idea that knowledge could be centred on the human knower, and sought what they considered a more secure foundation for knowledge.

In phenomenology this foundation would be experience itself; in structuralism, knowledge was to be founded on the "structures" that make experience possible: concepts, and language or signs. Post-structuralism, in turn, argued that founding knowledge either on pure experience (phenomenology) or systematic structures (structuralism) was impossible. This impossibility was meant not to be a failure or loss, but a cause for "celebration and liberation."

There are some theories of post-structuralism :
1)    General practices
Post-structural practices generally operate on some basic assumptions:
a.    Post-structuralists hold that the concept of "self" as a separate, singular, and coherent entity is a fictional construct. Instead, an individual comprises tensions between conflicting knowledge claims (e.g. gender, race, class, profession, etc.). Therefore, to properly study a text a reader must understand how the work is related to his or her own personal concept of self. This self-perception plays a critical role in one's interpretation of meaning. While different thinkers' views on the self (or the subject) vary, it is often said to be constituted by discourse(s). Lacan's account includes a psychoanalytic dimension, while Derrida stresses the effects of power on the self. This is thought to be a component of post-modernist theory.

b.    The author's intended meaning, such as it is (for the author's identity as a stable "self" with a single, discernible "intent" is also a fictional construct), is secondary to the meaning that the reader perceives. Post-structuralism rejects the idea of a literary text having a single purpose, a single meaning, or one singular existence. Instead, every individual reader creates a new and individual purpose, meaning, and existence for a given text. To step outside of literary theory, this position is generalizable to any situation where a subject perceives a sign. Meaning (or the signified, in Saussure's scheme, which is as heavily presumed upon in post-structuralism as in structuralism) is constructed by an individual from a signifier. This is why the signified is said to 'slide' under the signifier, and explains the talk about the "primacy of the signifier."

c.    A post-structuralist critic must be able to use a variety of perspectives to create a multifaceted interpretation of a text, even if these interpretations conflict with one another. It is particularly important to analyze how the meanings of a text shift in relation to certain variables, usually involving the identity of the reader.
2)    Destabilized meaning
In the post-structuralist approach to textual analysis, the reader replaces the author as the primary subject of inquiry. This displacement is often referred to as the "destabilizing" or "decentering" of the author, though it has its greatest effect on the text itself. Without a central fixation on the author, post-structuralists examine other sources for meaning (e.g., readers, cultural norms, other literature, etc.). These alternative sources are never authoritative, and promise no consistency.
In his essay "Signification and Sense," Emmanuel Lévinas remarked on this new field of semantic inquiry:

“language refers to the position of the listener and the speaker, that is, to the contingency of their story. To seize by inventory all the contexts of language and all possible positions of interlocutors is a senseless task. Every verbal signification lies at the confluence of countless semantic rivers. Experience, like language, no longer seems to be made of isolated elements lodged somehow in a Euclidean space... [Words] signify from the "world" and from the position of one who is looking”. (Lévinas, Signification and Sense, Humanism of the Other, tr. Nidra Poller)

3)    Deconstruction
A major theory associated with Structuralism was binary opposition. This theory proposed that there are certain theoretical and conceptual opposites, often arranged in a hierarchy, which human logic has given to text. Such binary pairs could include Enlightenment/Romantic, male/female, speech/writing, rational/emotional, signifier/signified, symbolic/imaginary.

Post-structuralism rejects the notion of the essential quality of the dominant relation in the hierarchy, choosing rather to expose these relations and the dependency of the dominant term on its apparently subservient counterpart. The only way to properly understand these meanings is to deconstruct the assumptions and knowledge systems which produce the illusion of singular meaning. This act of deconstruction illuminates how male can become female, how speech can become writing, and how rational can become emotional.
