What a Distinction Must Carry: Self-Registration and the Hard Problem

The hard problem takes description from outside as the measure of what there is, and assesses experience by that measure. On one minimal ontological posit, this paper examines a prior question: when a distinction obtains with no registrar outside itself, what keeps it in place? We call the answer "registration", in a constitutive sense, and argue that registration cannot come from outside everywhere: the whole of what there is registers itself. The main rival, mutual registration as developed in ontic structural realism, for all its precision, reduces either to external registration or, in closed loops, to self-registration. Within the whole, a distinction registers itself if it is a stable lock: a form, not a place, that holds itself through at least one constraint of its own, a constraint that the form itself produces and that returns it after a deviation. The self-registration of such a distinction is its inner side; it differs from information and from knowledge, and no external registration can take its place. Every genuine distinction, living or non-living, is therefore two-sided, while a boundary drawn only by an observer is not. If, as the paper argues, the being-for-someone of experience is a form of self-registration, the hard problem loses its footing in the coordinates in which it is posed: experience does not arise from what has no inner side. The question is relocated to the horizon of each focus: which self-registrations are experiences, and by what law the degrees of the two sides vary together. Relation to earlier work: Some ideas developed here were first sketched in an earlier preprint posted under a different title (https://doi.org/10.17605/OSF.IO/2Y3BN). The present paper is a new work, with a different argument, structure and text.
