The article reconstructs the unfinished dialogue between Arnason and Castoriadis, with a particular emphasis on the problematic of world articulation. Arnason’s thought is situated as reconfiguring classical sociological constellations, especially as they pertain to the revitalization of the civilizational problematic and the emphasis on the philosophical dimension of sociological investigation. His interpretative framework is located within the nascent field of post-transcendental phenomenology, which he elaborates via the overlapping problematics of cultural articulations of the world as an inter-cultural horizon, and the (...) human condition as various modes of being-in-the-world. Arnason’s encounter with Castoriadis is considered. Despite the many points of fruitful contact, Castoriadis’ neglect of the phenomenological question of the world as a ‘shared horizon’ is, in Arnason’s view, too great to overcome; Arnason looks instead to Weber, Merleau-Ponty and, more recently, Patočka for interpretative resources. Although Castoriadis’ elucidation of the world proceeds ‘in fragments’, the article contends that hermeneutical reconstruction of his thought reveals openings onto the problematic of elemental world orders that can further the dialogue with Arnason.
