Beyond Existential Fatalism: Existentialism, Post-Structuralism, and the Reconstruction of Being through Belonging

This article critically examines the ontological assumptions underlying four major contributions to twentieth-century philosophy: Heidegger’s analysis of Being, temporality, and anxiety; Sartre’s conception of individual freedom; Foucault’s historical analysis of power; and Derrida’s deconstruction of definitive knowledge. The central argument is that these philosophical approaches, despite their extraordinary intellectual achievements, risk treating certain conditions of human existence as ontologically necessary without sufficient scientific justification. These conditions include existential anguish, loneliness, subjection to power, and the impossibility of definitive knowledge. The article does not suggest that these philosophers advocate resignation or deny the possibility of overcoming such difficulties. Rather, it questions whether the difficulties they identify must constitute the fundamental starting points of human existence. The Philosophy of Belonging offers an alternative ontological framework based on four principles: Being Is Belonging; Belonging Is Always Imperfect; the Synchronic and Diachronic Dimensions of Belonging; and the Differentiation and Interdependence of Material, Biological, and Institutional-Human Strata. Drawing on findings from the biological and social sciences, the article argues that adequately developed belonging can make existential anguish, loneliness, and domination nonnecessary outcomes. It further maintains that the impossibility of absolute knowledge does not prevent the progressive development of objective scientific and technical understanding. A central contribution concerns individual freedom. Freedom does not imply loneliness; rather, it arises from imperfect belonging and becomes effective through adequately developed relationships. Individual differentiation and creativity, in turn, provide essential foundations for social adaptability. The article develops the three avenues of human belonging—love, social significance, and existential significance—and proposes a fallibilist research program connecting individual development, institutional transformation, scientific knowledge, and collective adaptability.
