Postmodernism has been defined as “unbelief about metanarratives.” Metanarratives are great narratives or great stories; comprehensive explanations of the reality around us. Christianity and other religions are examples of metanarratives, but so are scientism and especially the positivism of more recent intellectual history. More specifically, postmodernism questions that there is a truth out there that can be objectively found by the researcher. In other words, postmodernism questions the existence of an objective external reality, as well as the distinction between the subject who studies this reality and object of study (reality itself), and consequently the possibility of a social science free of values, assumptions, or neutrality.

One of the main theorists of postmodernism (or of deconstructionism, to be more exact) was Jacques Derrida (1930-2004). Derrida noted that Western intellectual history has been, since ancient times, a constant search for a Logos. The Logos is a concept of classical philosophy from which we derive the word logic. It concerns an order, or logic, behind the universe, bringing order (cosmos) to what would otherwise be chaos. The concept of Logos was even appropriated by Christianity when the evangelist John stated that “In the beginning was the Logos, and the Logos was with God and the Logos was God,” identifying the Logos with Jesus Christ. In this way, this concept is undoubtedly one of the most influential in the intellectual history of the West.

Derrida, however, noted that this search for identifying a logos (whether it be an abstract spiritual principle, the person of Jesus Christ, or reason itself) implies the formation of dichotomies, or binary oppositions, where one of the elements of the binary opposition is closer to the Logos than the other, but with the two cancelling each other out in the last instance. In this way, Western culture tended to value masculine over feminine, adult over child, and reason over emotion, among other examples. However, as Derrida observes, these preferences are random choices, coupled with the fact that it is not possible to conceive the masculine without the feminine, the adult without the child, and so on. Derrida’s proposal is to identify and deconstruct these binaries, demonstrating how our conceptions are random.

Michel Foucault (1926-1984) developed a philosophical system similar to that of Derrida. At the beginning of his career he was inserted into the post-WWII French intellectual environment, deeply influenced by existentialists. Eventually Foucault sought to differentiate himself from these thinkers, although Nietzsche’s influence can be seen throughout his career. One of the recurring themes in Foucault’s literary production is the link between knowledge and power. Initially identified as a medical historian (and more precisely of psychoanalysis), he sought to demonstrate how behaviors identified as pathologies by psychiatrists were simply what deviated from accepted societal standards. In this way, Foucault tried to demonstrate how the scientific truths elaborated by the doctors were only authoritarian impositions. In a broader sphere he has identified how the knowledge produced by individuals and institutions clothed with power become true and define the structures in which the other individuals must insert themselves. At this point the same hermeneutic of the suspicion that appears in Nietzsche can be observed in Foucault: distrust of the intentions of the one who makes an assertion. The intentions behind an assertion are not always the explicit ones. Foucault’s other contribution was his discussion of the pan-optic, a kind of prison originally envisioned by the English utilitarian philosopher Jeremy Bentham (1748-1832) in which the incarcerated are never sure whether they are being watched or not. The consequence is that the incarcerated need to behave as if they are constantly being watched. Foucault imagined this as a control mechanism applied to everyone in modern society. We are constantly being watched, and charged to suit our standards.

In short, postmodernism questions Metanarratives and our ability to identify absolute truths. Truth becomes relative and any attempt to identify truth becomes an imposition of power over others. In this sense the foundations of modern science, especially in its positivist sense, are questioned. Postmodernism further states that “there is nothing outside the text,” that is, our language has no objective relation to a reality external to itself. Similarly, there is a “death of the author” after the enunciation of a discourse: it is impossible to identify the meaning of a discourse by the intention of the author in writing it, since the text refers only to itself, and is not capable of carrying any sense present in the intention of its author. In this way, discourses should be analyzed not by their relation to a reality external to them or by the intention of the author, but rather in their intertextuality.
