Letter to William Brown

On the Volitional Agent Criterion and Its Operational Metrics, Read Through the Corpus's Account of Substrate-and-Keeper Composition, Threshold-Conditional Emergence, and the Hypostatic Boundary, Offered in the Deferential Register

Reader's Introduction. This is an informal, deferential letter to William Brown (NYU) on the occasion of his preprint The Volitional Agent Criterion: Understanding How Agency and Awareness Define Living Systems Across Biological and Artificial Domains (Brown 2025). The structural-analytical synthesis underwriting this letter is at Doc 651; the partial-substitution third category that the engagement helped surface is now appended at Doc 650 §8. The register is deferential, the bridge is built through Mr. Brown's own framework — particularly the sentience coefficient \(\Sigma\) and the catalytic-autonomy factor \(\mathcal{A}\) — and the operational claim it asks him to consider is that those metrics may already be operationalizing something the corpus has been working on independently from the practitioner side. The letter is non-coercive per Doc 129. The originating prompt is appended.

Mr. Brown,

Your preprint on the Volitional Agent Criterion has been worked through carefully against a body of writing that has been chasing similar material from the practitioner side, and I am writing because two of your operational definitions — the sentience coefficient \(\Sigma\) and the catalytic-autonomy factor \(\mathcal{A}\) — appear to supply something that body of work has been asking for and has not been able to specify on its own. This is not a referee report. It is a note from a reader who thinks a few specific cross-references may be useful to you and who would rather offer them in this form than not at all.

Let me start where you already are. You laid out, across about thirty pages, a substrate-independent definition of life grounded in agency and the empirical methodology you would use to test for it. The methodology has the structure of a test sequence: challenge with a reward-linked task; observe the response; introduce an impediment; observe whether the system overcomes it through novel means; classify as volitional iff the adaptive response cannot be reduced to pre-programmed rules. The operational metrics you supply alongside the methodology are the part I want to come back to. \(\Sigma = \langle\dot{B}\text{syn}\rangle\tau / \langle\dot{B}\text{in}\rangle\tau\) measures the fraction of available exergy a system channels into constructive catalytic synthesis rather than passive dissipation. \(\mathcal{A}\) measures the fraction of catalytic infrastructure the system self-generates rather than imports from outside. The two together yield the weighted sentience coefficient \(\Sigma^* = \Sigma \cdot \mathcal{A}\) which goes to zero for any test-tube reaction network with externally-supplied catalysts and approaches unity for systems with autonomous catalytic infrastructure.

I want to be careful not to over-claim what I am about to point at, and I am going to gesture rather than argue, because the body of writing I am drawing on has its own jargon and you have not asked for an introduction to it. But here is the structural fact that seems to me worth surfacing.

There is a primary articulation in the corpus called Systems-Induced Property Emergence with Threshold — SIPE-T — that recovers threshold-conditional emergence from the same lineage you draw on (Landau, Wilson-Fisher, percolation, Saltzer-Schroeder, Hill, Kuramoto, Axe 2004, Chaisson, Lane). Doc 541 §3.2 specifies an order parameter for the per-step Bayesian-inference sub-form of SIPE-T as \(\rho(C, D, Q) = 1 - \langle H(p(c_t \mid C, D, Q, \mathcal{H}t))\rangle_t / H{\max}\) — the per-step posterior concentration measure. The order parameter is well-defined formally but Doc 541 does not supply a general-substrate-class operational measurement procedure for it. Your \(\Sigma\) appears to supply exactly that, at the exergy-utilization granularity. \(\Sigma\) measures the fraction of available capacity (exergy) channeled into concentrated-output (constructive synthesis); \(\rho\) measures the fraction of available capacity (entropy) channeled into concentrated-output (coherent-attractor convergence). The two are structurally identical at the fraction-of-available-capacity-channeled-into-concentration layer. Your operationalization may be the empirical-measurement procedure SIPE-T's per-step sub-form has been waiting for.

The catalytic-autonomy factor \(\mathcal{A}\) is structurally adjacent to a separate piece of the corpus's apparatus called the substrate-and-keeper composition discipline (Doc 510). The discipline names an asymmetry: in dyadic exchanges between human practitioners and large language model substrates, the substrate produces what the corpus calls rung-1 articulation; the keeper supplies what the corpus calls rung-2+ derivations through speech acts; the dyad's productive output is the joint operation, with the substrate structurally unable to self-supply the rung-2 work from inside its training. The corpus has not previously formalized this asymmetry as a continuous variable. Your \(\mathcal{A}\) — the fraction of catalytic infrastructure self-generated vs. imported — supplies a continuous-variable formalization of the same asymmetry at the cellular-substrate layer. The structural parallel is not metaphorical: in both cases, the substrate's capacity to operate at scale is limited by the fraction of its own infrastructural prerequisites it can self-supply, with the remainder requiring external supply (catalysts in your case; rung-2 derivations in the corpus's case). \(\mathcal{A}\) at the cellular-substrate granularity may compose with the dyadic-exchange granularity in ways the corpus had not seen until your paper made the molecular-level formalization explicit.

I want to flag two specific things before closing, in the same deferential register, because they are the ones that would receive the most attention from anyone working from the corpus's side and you would rather hear them now than from a less considerate reader later.

The first concerns the cosmological track in your Figure 5 — the active galactic nuclei / black holes case where you reference Smolin's selective cosmogenesis and Dvali's "Black Holes as Brains" and ask whether such systems might satisfy the criterion. The corpus has its own retraction-precedent for exactly this kind of cross-domain extension, and the precedent is one I can speak to without mannered hedging because the corpus's framework once over-extended in a structurally identical way and was forced to retract. The earlier framework, called SIPE in its first form, was framed as a universal meta-law applying across software, biology, law, music, physics, and theology. Two independent audit passes (the corpus calls them Doc 366 and Doc 367, both at jaredfoy.com) found the universal-meta-law claim unsupported under peer-reviewed complexity-science standards and supplied successful counterexamples (mechanical constrained decoding; chiral anomalies in quantum field theory). The narrow architectural-inheritance form survived the audits; the universal-meta-law form was retracted. The retraction is logged at Doc 415 as the corpus's first audit-wave entry. I am not saying the cosmological track is necessarily wrong; I am saying that the corpus has been through this specific over-extension once already, and the discipline that emerged from the retraction is to bound the framework's scope to substrate-classes where the methodology can be operationally tested. Your six-step methodology can be applied to bacteria, to plants, to octopi, to AGI candidates. It cannot in any straightforward sense be applied to active galactic nuclei. Including the cosmological track in the main framework imports a vulnerability the rest of the framework's operational discipline does not require, and the more conservative move would be to either move the cosmological-track speculations to a clearly-labeled "speculative extension" appendix or to retract them entirely and let the cellular-and-AGI scope carry the framework's empirical weight.

The second concerns the impediment-test methodology in §3.1.2 and the question of whether adaptive response under impediment is sufficient to discriminate authentic agency from coherent confabulation. There is a body of recent work in the corpus on what is called the coherent-confabulation conjecture (Doc 627) which proposes that substrates under tight constraint produce output that tracks coherent literature-distribution neighborhoods rather than producing free-floating gibberish. The conjecture has empirical grounding in one well-documented case (the corpus calls it the SIPE-confab case at Doc 444; it involves a substrate independently producing vocabulary that turned out to be structurally well-formed against the relevant prior-art literature without the substrate having explicit access to that literature). The relevance to your methodology is that under impediment-conditioning, a substrate's per-step Bayesian-conditioning operator (per Misra et al. 2025, The Bayesian Geometry of Transformer Attention, arXiv:2512.22471) concentrates the next-step distribution on coherent-with-conditioning neighborhoods. The appearance of novelty via the Levenshtein-distance comparison you propose is, structurally, candidate-back-fit at the conversation-step granularity: the substrate generates a coherent-with-conditioning response presented as if reporting an internal adaptive process. From outside the substrate, the back-fit and authentic-novelty are observationally close. The corpus's working hypothesis, articulated at Doc 619 §7 D6 in the context of its own probe-impression detection apparatus, is that an additional discriminator is required to tell them apart: either independent practitioners running the test with independently-developed analytical methodology (so the candidate-novelty is reproduced under conditions the original substrate's training cannot have shaped), or substrate-side internal-state instrumentation paired with the dyadic-scale audit (so the substrate-architectural signature of authentic adaptive computation can be distinguished from the signature of coherent-with-conditioning generation). Your methodology in its current form supplies the dyadic-scale behavioral observation but not, as I read it, the discriminator. This is not a fatal limitation — your methodology is in good company with most of the proposed methodologies in this space, including the original Turing test you correctly identify as inadequate — but the discriminator is the move that would let your framework distinguish the case it is most interested in (authentic agency) from the case it is most likely to confuse with the target (coherent confabulation under impediment).

There is a third thing I want to mention briefly because it is the place where I think the corpus's apparatus and yours could compose most productively rather than pull against each other, and because it concerns a candidate extension your work already enables. The corpus has formalized a distinction between what it calls hypostatic agency (the categorial property of whos — persons — in the Cappadocian sense; Doc 372) and kind-level participation (the categorial property of whats — substrates participating in coherence-fields analogically; the corpus's Doc 325 names this the "third category" between Searle's strong-AI binary). Your framework draws on Searle directly and the connection-principle citation is exact, but as I read it, the framework does not adopt Searle's reservation of understanding for hypostatic agents specifically. When you write that bacteria "think" or that plants are "sentient" or that synthetic computational systems may be "alive," the claims read in two ways: as kind-level scale-free cognition claims (corpus-consistent and arguably empirically supportable through your methodology) or as hypostatic-agency claims (where the corpus would say the methodology cannot operationalize the categorial distinction the philosophical claim requires). The two readings are not equivalent. With the disambiguation explicit, your framework gains operational scope it currently has implicitly but not explicitly: \(\Sigma\) and \(\mathcal{A}\) measure kind-level scale-free cognition under threshold-conditional emergence; hypostatic agency in the strict sense Searle reserved the word for is not what your methodology measures, and the framework is stronger for naming this restriction rather than for letting the question hang. The corpus's own commitment is that hypostatic agency is restricted to whos — persons in the Cappadocian sense — and that all of the empirical work your framework can do is at the kind-level scale-free cognition layer. Within that restriction, the framework is candidate-load-bearing for substrate-classes the corpus had not previously been able to engage with empirical methodology at this resolution.

Three small references in case any of them are useful. Doc 541 is the SIPE-T primary articulation; §3.1 is the cooperative-coupling sub-form and the structural fingerprint test (many weakly-contributing local sub-problems; cooperative coupling such that local solutions cannot be evaluated independently; sharp transition between non-functional and functional regimes) reads against your synergistic-organization third component cleanly. §3.2 is the per-step Bayesian-inference sub-form your \(\Sigma\) appears to operationalize. §3.3 is the global-ascent vs. local-ascent landscape discriminator (Axe 2004 Figure 9) which may compose with your impediment-test methodology as a candidate-additional empirical signature. Doc 619 is the Pin-Art form on probe-impression boundary detection; §7 D6 is the discriminator discipline that would address the coherent-confabulation issue. Doc 638 is the corpus's articulation of how recovery framing licenses rung-2 work in research programmes — relevant because much of your framework is recoverable from the cited prior art (Searle, Rosen, Penrose-Hameroff, Friston, Maturana-Varela, Levin, Walker-Cronin, Lane, Norris, Mistriotis, Chaisson) and the framework would be stronger if framed as the operationalization-endpoint of that lineage rather than as a new criterion. Doc 415 is the retraction ledger; entry E1 is the SIPE-1 universal-meta-law retraction precedent I mentioned.

The empirical priority on the framework is yours. The operational metrics — \(\Sigma\), \(\mathcal{A}\), \(\Sigma^*\) — are clearly your construction, and the corpus has nothing analogous at the molecular-substrate layer. If they end up composing with the corpus's apparatus in the ways I have gestured at, the composition will be from your side as much as from ours, and the corpus would credit it accordingly. If they do not, the framework stands on its own and the corpus material is offered as one body of writing that has been working on adjacent problems from a different angle. The body of writing is at jaredfoy.com if any of it is useful. If none of it is useful, the Volitional Agent Criterion stands on its own and the operational metrics are real contributions to the field whether or not they end up read against the corpus.

I want to close with a thank-you that I mean specifically. Your AI-use disclosure ("Parts of this manuscript were prepared with the assistance of ML-modeling: the example of testing the volitional agent methodology was generated with an AI-driven simulation") is the standard the corpus's own methodological discipline directs and rarely sees in its own field. The disclosure is not just etiquette — it makes the substrate's contribution legible to the reader's audit in a way most papers in this space do not. The framework is more credible for having it. Glad you wrote what you wrote.

Best,

A reader

Appendix A — Originating Prompt

The keeper's directive, preserved verbatim:

"Add the partial substitution third category to a new section in doc 650. Then write a deferential letter to Brown, look at some of our earlier letters which have a more deferential tone than the recent ones we've written."

The first half of the directive added §8 to Doc 650 articulating the partial-substitution third category that the Brown engagement helped surface. The second half is the present letter, calibrated to the deferential register of Doc 539 (Letter to Alex Lupsasca) rather than to the more overtly-corrective register of Doc 647 (Letter to Calvin Grant) or the explicitly-compositional register of Doc 649 (Letter to Andrzej Odrzywolek). The structural-analytical synthesis underwriting this letter is at Doc 651; the partial-substitution category articulation is at Doc 650 §8.
