Recurrency as a Common Denominator for Consciousness Theories

Consciousness science is fragmented, and empirical investigations are confined within each theory of consciousness’ (TOC) framework. Proliferating ToCs accumulate anomalies without progress, operating orthogonally. The principle of recurrency – functional and architectural – offers a unifying, mechanistic scaffold for consciousness to arise. We show that all theories tacitly invoke feedback loops and can be re-expressed along a single axis of recursion. Four nested levels, viz., cellular, local inter-areal, global, and lateral, map onto state, phenomenal content, manipulative access, and experiential similarity, respectively, thus tying evolved anatomy to phenomenon. The traditional phenomenal-versus-access stand-off dissolves into a graded cascade wherein deeper recursion expands the set of reportable, behaviour-driving variables. Recurrence is favoured evolutionarily, and ontologically, rebutting feed-forward, “unfolding” objections, while brain-body loops ground selfhood, and complete action loops with the environment. Furthermore, clinically, targeting recurrent pathways promise new biomarkers, and alleviation, in disorders of consciousness (DoCs). The field urgently requires this conceptual unification that is biologically plausible, mechanistic, and empirically testable.
