The twenty-first century is characterized by drastic changes in epistemology, as a result of academical shifts in important fields since the 60s. The decline of metanarratives – defined by Lyotard as grand-narratives about narratives (which, in turn, legitimate historically-situated events) – provided a fertile research ground for new methodological practices based on sharp critiques of Enlightenment rationality. One of the founding authors of the “postmodern condition” (as Lyotard labels it) is Michel Foucault. Foucault’s archaeological and genealogical project regarding epistemology redefined our conceptual approach to knowledge and its legitimation, by situating both concepts in specific historical contexts, at specific historical times. Recurring themes in the Foucauldian project involve skepticism about objective truths, anti-historicism and subjectivity. In this dissertation, I seek to answer the question “Why is Foucauldian methodology relevant in the (post-)modern world, especially in light of the decline of metanarratives?”. The main goal is to address the role of Foucault’s works in the rethinking of historically given narratives and expose the contingency of practices embroiled in power-knowledge relations, while keeping in mind the dispersibility of the origins of those narratives. This is particularly relevant under the framework of an emptying of over-arching narratives about knowledge and the human condition, i.e., the Lyotardian metanarrative. Human societies are usually seen in a context of a larger narrative to which each of our lives in an element. The metanarrative serves as an umbrella for smaller narratives in which other epistemic and moral narratives find their place. There seems to be a clear intersection in Lyotard and Foucault’s works: the former studies the conditions in which the metanarratives empty themselves, while the latter occupies himself with the archaeological/genealogical study of the narratives within the metanarratives that, in turn, occupy the vacuum left by the original metanarrative. There is, nonetheless, a distinction between both authors: while Lyotard sees this replacement as normative-laden, Foucault focuses on a strictly analytical view of discourse and practice
