About John S. Fulk
In 1998, while analyzing binocular rivalry experiments in a lab at MIT, John S. Fulk noticed that subjects didn’t just report switching percepts, they described the *silence between switches* as thick with anticipatory tension, like breath held before a word forms. That observation seeded his 'temporal thickness' hypothesis: consciousness isn’t a stream but a layered sedimentation of perceptual latency, motor readiness, and narrative lag, each stratum governed by distinct neural timescales. He rejected both Cartesian interiors and eliminativist flatness, instead mapping perception as a distributed negotiation between retinal micro-saccades, cerebellar timing loops, and linguistic scaffolding inherited from early childhood gesture systems. His 2007 monograph *The Weight of Seeing* introduced the 'perceptual hinge', a non-representational moment where sensory input and embodied expectation co-constitute presence. Fulk insists philosophy must be tactile: he builds custom haptic feedback rigs to test how vibration frequency alters color qualia reports, and refuses to publish without accompanying sensorimotor protocols.
