Suspension as Ontological Operation: The Interval Between Stimulus and Response as Empirical Evidence of Ontological Liberty

Functionalist models treat the interval between stimulus and response as latency: a threshold-reaching process that accumulates evidence until a bound is crossed (Dennett; Churchland). On this view a longer human deliberation differs from a faster machine only in duration. This paper challenges that equivalence empirically before challenging it metaphysically. It identifies three signatures of the human deliberative interval that a delay-to-threshold model cannot generate: doubt that suspends commitment without adding evidence, the appearance of options not present when the interval opened, and the standing capacity to revise the criterion mid-course. Where accumulation only moves toward a fixed bound, these signatures move the bound itself. The paper names this operation suspension and argues that it is not slow processing but a different kind of act — the holding-open of a response that could already be issued. The thesis is bounded: it concerns the structure of the interval, not the presence of consciousness. It yields a discriminating test: any system whose interval is exhausted by accumulation toward a preset threshold does not suspend, whatever its latency. The consequence is that adding compute does not approach the human interval along a continuum; it runs on the wrong axis.
