Post-authorship is a philosophical concept developed by Remilia Corporation that rejects traditional notions of individual creative ownership, proposing instead a model where art emerges from collective consciousness and flows freely through networks without attribution constraints. The concept positions artistic creation as a channeling process rather than individual invention, advocating for permissionless remixing and sharing as essential to cultural evolution. Post-authorship forms a core tenet of Remilia's artistic philosophy alongside other concepts like post-identity and network spirituality.
