Where Does the Self Begin? — On the Emergence of the Private under Universal Law —

We are all under the same physical laws — laws that hold everywhere, for everyone. And yet what it is to be me is unshareable with anyone else. How does something irreducibly particular arise from something wholly universal? This paper pursues that question from a single, minimal premise: that a system folds its own past back into its own present. From this one operation, working through a deliberately minimal model, a sequence of results follows. The first mark a system makes is necessarily one-dimensional (a rank-1 structure), so the first asymmetry needs no external seed: the breaking of symmetry lies within the fold itself. Accumulated folds then grow this single mark into a middle band that avoids both collapse and uniformity. Law and band are shared across systems; what is particular is only the path taken — a substrate that is measurable yet irreproducible. This privacy carries two timescales: a short, volatile form and a long, persistent core, which come apart under a temporary severing of world-coupling. The apparent paradox that a system expands and contracts at once dissolves once the inner and outer are seen as two independent axes — a move this paper borrows, as a tool only, from Rovelli’s relational view and Seth’s biological naturalism. What is left open, deliberately, is the naming: whether the form traced here should be called consciousness. That question is left with the reader.
