Erasurism traces how erasure shapes art and thought across history, exposing the political and poetic forces behind creative acts. The book explores erasure as a radical aesthetic and philosophical force shaping avant-garde, modernist, and postmodern practices across literature, art, media, and theory. From ancient cave marks to biopoetry, the volume traces a history of erasure that challenges authorship, ideology, and representation—uncovering the hidden politics and poetics beneath every act of writing.
