The proposed performance lecture presents the outcomes of several years of collaborative research through a living constellation of academic reflection, artistic exploration, and a shared live experiment. Three subgroups contribute performative interventions that remain in continuous relation to theoretical articulation and dialogical reflection, forming an integrated process in which thinking, sensing, and acting are closely intertwined. The postsecular appears as an ambivalent, processual phenomenon emerging through movement, tension, and relational intensity. A central focus lies on the bodily and somatic dimensions of postsecular experience. The lecture-performance explores how postsecular dynamics become perceptible through embodied affects, gestures, rhythms, attentional practices, and vulnerability. The performative functions as a medium in which spiritual, existential, and material dimensions converge, with knowledge emerging through the body as a site of resonance and transformation. Structured as a participatory situation, the event involves the audience as co-present contributors whose perception and embodied responsiveness shape the unfolding process. Participation is understood as shared exposure and attentiveness, enabling postsecular dynamics to be experienced collectively. Finally, the experimental format reconfigures power relations in academic knowledge production. By fostering horizontal interactions among speakers, performers, and participants, the lecture-performance creates a relational space in which authority circulates and knowledge emerges through interaction.
