Emerging within late 20th-century reconfigurations of embodiment, sensation, and evental materialism, Affect Atmospheres & Non-Representational Flows functions as a pivotal conceptual infrastructure for theorising the pre-conscious, infra-semiotic dimensions of experience. Operating not through representational capture but through modulation, this node activates a mode of thought attuned to processes of emergence, intensities without form, and the infra-logical structuring of subjectivation. Its epistemic architecture displaces linguistic or symbolic priority in favour of affective gradients, moving across fields such as political ontology, architectural atmospherics, neuroaesthetics, and movement studies. As a political-symbolic technology, it frames affect as a medium of control and potentiality, foregrounding how non-discursive forces—gradients, tensions, resonances—mediate social space and power without recourse to stable identities or fixed representations. Infrastructurally, it undergirds a shift from representational critique to modulatory pragmatics, wherein design, governance, and sensation are understood as co-extensive fields of atmospheric calibration. The figure of the body here is not that of an expressive agent but a sensing surface, a relay for transindividual forces that exceed cognition and traverse assemblages of architecture, media, and habit. Stabilised as a canonical relay-point in the ArtCanon, this node recodes perception as an ontogenetic field—irreducible to form, yet central to form's emergence.
