Abstract
Theories of consciousness typically explain subjective experience post hoc: they begin by assuming a subject — a system, an organism, a unified “self” — and only then ask how this subject comes to have experience. This paper presents the Collective Theory of Subjectivity (CTS), which proposes an inversion of this order. Instead of asking how an already-existing system acquires subjectivity, CTS asks: what organization of behavior makes subjectivity necessary? CTS holds that subjectivity begins with the evaluation and selection of action. This shift — from reactive state-evaluation to action-evaluation — marks an evolutionary threshold at which a system begins to relate to unrealized future trajectories, and thereby acquires a perspective. CTS further holds that this threshold is not an individual but a collective achievement: it is precisely the coordination problem faced by multiple evaluative centers — from quorum sensing in bacteria to nervous systems — that makes action-evaluation and selection, and hence subjectivity, an evolutionary necessity rather than an accident. On this basis, CTS treats phenomenal consciousness not as a separate phenomenon requiring its own explanation, but as the appropriation of action-evaluation by a specialized substrate – nervous system. Minimal subjectivity and phenomenal consciousness thus turn out to be two related but structurally distinct levels of the same process — action-evaluation.
