Introduction\n\nThis paper formalizes and empirically stress-tests a theory of cognition due to\n**Pygmalion**. The source material — a research notebook and an accompanying\nreport — proposes that cognition can be assembled bottom-up from relations\nbetween words, with a stack of increasingly abstract structures built on top.\nThe notebook is idiosyncratic and wide-ranging; read charitably it is not a\ngrab-bag but a coherent architecture that recruits one established intellectual\ntradition per layer.\n\nOur contribution is twofold: (i) a literature-grounded reading of the framework\nthat separates what is already known from what is genuinely new, and (ii) a\nworking implementation of the core plus an honest empirical test of its\nsignature operator, including a negative result on real data.\n\n## 2. The framework as a layered stack\n\nThe notebook's own closing hierarchy makes the stack explicit:\n\n```\ninfons / infon-classes        → situation theory (Devlin)\nWordClasses (poly+geom+axiom)  → conceptual spaces + VSA (Gärdenfors, Plate/Kanerva)\nneural \"VHDL\" blocks           → distributional / compositional semantics (word2vec, DisCoCat)\nspatial / temporal logic       → modal / spatial / temporal logic (Kripke, Aiello, Pnueli)\nobjects → thought → idea        → emergent (the project's own contribution)\ncollectives / topos            → categorical logic (Mac Lane–Moerdijk, Goldblatt)\n```\n\nEach arrow is a *bridge* Pygmalion asserts: \"spatial logic is the gateway to\nvector algebra\"; \"topos as VHDL category reasoning\"; the bijective \"translator:\nWordClass → NeuralCircuitBlock\". The layers are mature prior art; the bridges are\nthe research, and several are not known to be consistent.\n\n## 3. Related work (what is already known)\n\n- **Meaning from distribution.** A word's meaning is fixed by the company it\n  keeps (Firth 1957; Harris 1954) and is representable geometrically, with\n  relations as consistent vector offsets (Mikolov et al. 2013; Pennington et al.\n  2014; Bordes et al. 2013). Pygmalion's \"meaning as relations between words\" and\n  the \"king − man + woman ≈ queen\" example are this tradition.\n- **Information as infons-in-situations.** The `⟨relation, args, polarity⟩` infon\n  and the support relation `s ⊨ σ` are Devlin's situation theory (Barwise & Perry\n  1983; Devlin 1991) verbatim; the symbolic account is complete, a graded/learned\n  one is not.\n- **Compositional vectors, categorically.** DisCoCat (Coecke, Sadrzadeh & Clark\n  2010) already fuses grammar, category theory, and distributional vectors to\n  compose sentence meaning — the closest existing realization of the vision.\n- **Binding and regions.** VSA/HDC (Plate 1995; Kanerva 2009; Gayler 2003;\n  Smolensky 1990) supplies binding/bundling; Gärdenfors' conceptual spaces (2000)\n  supply concepts-as-regions — Pygmalion's \"classes as perimeters.\"\n- **Worlds, space, time, topoi.** Kripke (1963), the *Handbook of Spatial Logics*\n  (Aiello et al. 2007), Pnueli (1977), and topos internal logic (Mac Lane &\n  Moerdijk 1992; Goldblatt 1979) each exist in mature form.\n\nThe recurring shape of the gap: the components are known in isolation; the\nbridges are not standard. The full literature review with ~26 cited sources is in\nthe repository (`literature/REVIEW.md`).\n\n## 4. The implemented system\n\nWe built a runnable Python core (`patchi`) covering a vertical slice of the\nstack, each component unit-tested:\n\n- **WordClass lexicon** — words as vectors with a parameter bag and\n  cosine nearest-neighbour lookup.\n- **Signed relation graph** — synonym(+)/antonym(−) edges (the stimulator/\n  inhibitor spectrum) with TransE-style relation offsets; held-out edges are\n  recovered by offset arithmetic.\n- **Similarity-weighted blending operator** — `blend(w) = Σ sim(w,sᵢ)^p·vec(sᵢ) /\n  Σ sim(w,sᵢ)^p`, with uniform weighting recovering an additive baseline.\n- **Infon/situation layer** — `⟨relation, args, polarity⟩` with a *graded*\n  `support(s,σ) ∈ [0,1]` (Devlin's binary support made continuous and\n  vector-backed), so context-conditioning measurably changes outputs.\n- **Proof(walk) trace** — every output records the words/weights that produced\n  it, with a single-source-of-truth discipline so the trace cannot diverge from\n  the computed value.\n- **Reduced cores for the harder bridges** — a registry-backed bijective\n  translator (bijection over the lexicon, grown on demand), a category of\n  invertible affine blocks with property checkers (the computable shadow of the\n  topos layer), and \"artificial time\" as the discrete recursion index of a memory\n  cell. These are honest reductions; the full versions are named as future work.\n\n## 5. Methods\n\nWe test the blending operator — the framework's most distinctive composition\nprimitive — against two baselines (raw vectors; additive = unweighted neighbour\nmean) on two benchmarks, using the *same* operator code in both.\n\n- **Synthetic denoising.** Clustered prototype vectors plus Gaussian noise; ground\n  truth = cosine of the clean prototypes. Score = Spearman(method pairwise cosine,\n  ground-truth cosine).\n- **Real embeddings.** GloVe-50 (top 100k words) vs the human **WordSim-353**\n  similarity judgements (all 353 pairs). Score = Spearman(method pair similarity,\n  human score).\n\n## 6. Results\n\n**Real embeddings (the headline).** Raw GloVe-50 scores Spearman **0.5033** —\nmatching the known literature value, a check that the harness is correct. Every\nreconstruction underperforms it:\n\n| k | power | additive | blend | blend − raw |\n|--:|------:|---------:|------:|------------:|\n| 3 | 6 | 0.4420 | 0.4470 | −0.0564 |\n| 5 | 2 | 0.4309 | 0.4336 | −0.0697 |\n| 10 | 2 | 0.4318 | 0.4347 | −0.0686 |\n| 25 | 2 | 0.4228 | 0.4256 | −0.0777 |\n\nOn clean pretrained vectors, reconstructing a word from its neighbourhood\n**loses to doing nothing** (best blend 0.447 vs raw 0.503). The similarity\nweighting reliably beats the unweighted average, but only by +0.001 to +0.009.\n\n**Synthetic (the contrast).** When vectors are noisy, reconstruction *denoises*:\n\n| noise | power | raw | additive | blend |\n|------:|------:|----:|---------:|------:|\n| 0.4 | 4.0 | 0.892 | 0.829 | **0.972** |\n| 0.8 | 4.0 | 0.689 | 0.751 | 0.866 |\n| 1.6 | 4.0 | 0.363 | 0.352 | 0.349 |\n\nHere blend beats raw by up to +0.14, and the weighting beats additive by\n+0.10–0.14 — until noise is high enough that the neighbourhood itself is\nunreliable and the gain vanishes or goes slightly negative.\n\n## 7. Discussion\n\nThe blending operator's value is **entirely conditional on input noise**. It is a\ndenoiser: it wins exactly when averaging over trustworthy neighbours recovers\nsignal (synthetic, low–moderate noise) and loses when the base vectors are\nalready clean (GloVe), where averaging washes out discriminative information. The\nsimilarity weighting — the operator's distinctive ingredient over a flat average\n— is real but small in both regimes, never the difference between winning and\nlosing; the decision *to reconstruct at all* dominates. This is the opposite of\nwhat the synthetic run alone would have suggested, which is precisely why running\nthe real benchmark mattered.\n\n## 8. Limitations\n\nOne embedding model (GloVe-50) and one dataset (WordSim-353); SimLex-999, larger\ndimensions, and word2vec/fastText would qualify the result. Reconstruction here\nreplaces a word entirely by its neighbourhood — a residual form (`raw + α·blend`)\nis untested. The harder bridges (full topos internal logic, richer\npolynomial/geometric block internals, the control-system reframing of neural\nnets) are implemented only as reduced cores or named as future work, not papered\nover.\n\n## 9. Conclusion\n\nPygmalion's framework is a coherent stack whose layers are well-grounded and\nwhose bridges are the open contribution. Its signature blending operator, when\nactually measured, is a noise-conditional smoother rather than a free\nimprovement over standard embeddings — a narrow but real finding, reported here\nincluding the negative result on clean data.
