The former need not be \u201cpre-objective\u201d; it may be the substrate from which objecthood is eventually stabilized.</p><p>Your Game of Life analogy puts the issue sharply: an observer can parse a run either as a succession of full configurations <code>S_0 \to S_1 \to S_2 \to \cdots</code>, or as a population of persisting things\u2014gliders, blinkers, guns, collisions. Neither description is simply false, but they privilege different invariants.</p><h2>The developmental thought</h2><p>For an infant, it is plausible to think the primary task is not initially \u201cthis is a bounded object with stable identity,\u201d but rather something closer to learning a <strong>predictive, sensorimotor continuity structure</strong>:</p><pre><code>(o_t, a_t) \mapsto o_{t+1},</code></pre><p>where <code>o_t</code> is an embodied perceptual state and <code>a_t</code> is movement, attention, action, or intervention.</p><p>On that framing, an \u201cobject\u201d is an economical construct: a reliable latent cause or track that helps make the stream compressible and predictable across occlusion, viewpoint change, manipulation, and interruption. Object permanence is then not merely adding a name to a visible thing; it is the achievement of a robust invariant over transformations in experience.</p><p>To objectify too completely or too early would mean choosing a decomposition before the organism has learned which distinctions remain stable under its own movements and under environmental change. That can be useful for action, but it also risks fixing the wrong ontology. In the GoL case, calling a pattern a glider depends on selecting an equivalence relation over board histories\u2014roughly, \u201cthe same up to translation after four ticks.\u201d At the raw board-state level, there are only changing bitmaps.</p><h2>Sequence-first versus object-first</h2><table><thead><tr><th>Perspective</th><th>Primitive</th><th>What it learns readily</th><th>What it can obscure</th></tr></thead><tbody><tr><td>Sequence / process-first</td><td>Transitions, relations, transformations, temporal regularities</td><td>Dynamics, causality, emergence, phase changes, conservation-like quantities, interaction patterns</td><td>Stable reference, compositional reuse, rapid categorization</td></tr><tr><td>Object / taxonomy-first</td><td>Bounded entities, attributes, kinds, persistent identities</td><td>Recognition, naming, memory compression, manipulation, social communication</td><td>Context dependence, processual identity, novel decompositions, system-level behavior</td></tr></tbody></table><p>A sequence-first perspective makes it more natural to ask questions like:</p><ul><li>What transformation class relates these states?</li><li>What is conserved, approximately conserved, or predictively sufficient?</li><li>At what temporal scale does a stable \u201cthing\u201d emerge?</li><li>Which distinctions matter only under intervention?</li><li>Is a purported object really an attractor, a quotient of trajectories, a recurrent motif, or a causal bottleneck?</li></ul><p>This is close to the difference between treating a glider as a primitive and treating it as a derived structure in a dynamical system. The second move is more universal because it can rediscover gliders, but also things that do not behave like objects at all: traveling waves, metastable regions, synchronization modes, causal cones, bifurcations, and statistical regularities.</p><h2>Your adjunction-shaped idea</h2><p>Your notation <code>[\Diamond \dashv \Box]</code> nicely captures a recurring \u201csyntax/model\u201d or \u201cpresentation/semantics\u201d movement.</p><p>The nLab page you linked describes the syntactic-category construction as a functor from a type theory <code>T</code> to a structured category <code>\mathrm{Con}(T)</code>, with contexts as objects and substitutions/interpretations as morphisms. Conversely, a suitable category carries an internal logic. In the stated adjunction, the unit</p><pre><code>T \longrightarrow \mathrm{Lan}(\mathrm{Con}(T))</code></pre><p>interprets a theory in the internal logic of its own syntactic category; the counit</p><pre><code>\mathrm{Con}(\mathrm{Lan}(C)) \longrightarrow C</code></pre><p>interprets the internal logic extracted from a category back in that category.[<a href="https://ncatlab.org/nlab/show/syntactic+category">ncatlab</a>]</p><p>That does resemble your \u201cGoL built on GoL\u201d thought, with an important qualification: the literal meaning of the unit and counit depends on precisely which categories of theories, models, and structure-preserving maps have been fixed. But the structural intuition is sound:</p><ul><li>A <strong>unit-like</strong> construction embeds a formal system into a richer account of its own possible semantic behavior.</li><li>A <strong>counit-like</strong> construction evaluates or realizes syntax recovered from a semantic world back in that world.</li><li>The induced monad or comonad records what is retained, added, normalized, freely generated, or forgotten by a round trip.</li></ul><p>For GoL, one possible instance would be:</p><ol><li>Start with board trajectories and the local update rule.</li><li>Construct a language whose terms describe local patterns, time shifts, translations, collisions, and perhaps finite causal cones.</li><li>Interpret those terms in the actual GoL dynamical system.</li><li>Ask which semantic structures survive a syntax\u2013semantics\u2013syntax round trip.</li></ol><p>Then \u201cglider\u201d is not assumed in the base language. It could arise as a definable or learnable equivalence class of spacetime patterns\u2014e.g. a localized configuration <code>p</code> such that for some period <code>k</code> and displacement vector <code>v</code>,</p><pre><code>F^k(p) = \tau_v(p),</code></pre><p>modulo a suitable treatment of background and finite support. A UTM would similarly emerge not merely as a large static pattern but as a structure carrying an interpreter-like universal property over encoded computations.</p><p>That feels closer to your universal notions: not a taxonomy of <em>what happens to be visible now</em>, but a language for transformations whose object concepts arrive as derived fixed points, quotients, or invariants.</p><h2>Where the scientific juice may be</h2><p>There are at least four potentially productive research programs hidden in this contrast.</p><h3>1. Objecthood as predictive compression</h3><p>Rather than defining objects through spatial segmentation alone, define them as latent variables that improve compression or prediction of a stream under transformations and interventions.</p><p>An object is good if it supports counterfactual continuity: \u201cif I look away, move, rotate, touch, or partially occlude the scene, what should remain inferentially available?\u201d This connects development, representation learning, state-space modeling, and causal abstraction.</p><p>The relevant question becomes: what is the smallest latent structure that preserves the agent\u2019s predictive and control-relevant information?</p><h3>2. Objects as quotients of histories</h3><p>A glider is better understood as an equivalence class of local histories than a single instantaneous configuration. More generally, define an equivalence relation on trajectory fragments:</p><pre><code>h \sim h'
\quad\text{if}\quad
h' \text{ is obtainable from } h
\text{ by allowable symmetries or has the same future-relevant behavior.}</code></pre><p>The quotient <code>H/{\sim}</code> gives \u201cobjects\u201d only after one decides what symmetries, temporal windows, and predictive consequences matter. This makes objecthood explicitly observer-, task-, and scale-relative without making it arbitrary.</p><h3>3. Multiscale ontology discovery</h3><p>A process-first learner can seek stable variables at multiple time scales:</p><ul><li>Pixels or cells at one scale.</li><li>Local motifs at another.</li><li>Coherent moving structures at another.</li><li>Interaction types and computational modules at another.</li><li>Global regimes, entropy rates, and attractors at another.</li></ul><p>Taxonomy then becomes a late-stage compression of a multiscale dynamical account, not the foundational ontology. That is especially appealing in GoL, where a \u201cthing\u201d may be stable only relative to a frame, a period, a background, a decoding convention, or a level of description.</p><h3>4. Categorical compositionality for learned abstractions</h3><p>Category theory may help most not by declaring what an object is, but by tracking how learned abstractions compose.</p><p>For example:</p><ul><li><strong>Morphisms</strong> can represent transformations, substitutions, interventions, or simulations.</li><li><strong>Functoriality</strong> asks whether an abstraction respects composition of changes.</li><li><strong>Adjunctions</strong> can formalize optimal approximation between an operational world and a symbolic description.</li><li><strong>Comonadic</strong> structure may model extracting local observable context from a global process.</li><li><strong>Monadic</strong> structure may model building richer state, effects, hypotheses, or computational interpretations from observations.</li></ul><p>The payoff would be a criterion stronger than visual resemblance: a learned category is useful when it preserves the compositional and counterfactual structure relevant to the system.</p><h2>On generative-video hallucinations</h2><p>Your response to generative video is philosophically interesting because it reverses the usual anxiety. Its errors do not merely look like factual mistakes; they expose how much human perception supplies stable objecthood on its own.</p><p>Generative video often preserves a <strong>style of local continuation</strong> while failing at identity through time: hands fuse, objects change count, tools lose causal relation to their users, geometry teleports, or a character\u2019s clothing ceases to be the same clothing. That is, it may produce something that is temporally fluent at a shallow level but has not committed to the persistence constraints that make an object an object for us.</p><p>So it can feel like an adversarial probe of one\u2019s own perceptual ontology. You see the point at which your visual system insists:</p><blockquote><p>No\u2014there must be one cup, one hand, one person, a continuing causal history.</p></blockquote><p>The model\u2019s oddness is not simply that it lacks objects. It may be that its learned \u201cobjects\u201d are distributed, conditional, and weakly bound across the temporal stream in a way unlike the robust causal individuals your perception constructs. It generates plausible adjacent frames without necessarily maintaining the same long-horizon equivalence classes of histories that you automatically treat as entities.</p><p>That makes the experience useful: it reveals that human objecthood is not just recognition of shapes. It is a very strong prior about <strong>identity under transformation</strong>, material continuity, causal coherence, and the permissible ways a world can change.</p><h2>A compact formulation</h2><p>One way to crystallize your hypothesis is:</p><blockquote><p>Perception begins as the learning of composable transformations on an experiential stream. Objects, kinds, and taxonomies are later-achieved quotient structures: stable, predictive, intervention-supporting equivalence classes of trajectories.</p></blockquote><p>In this formulation, \u201cobjectification\u201d is not the opposite of relational perception. It is a successful compression of it. The danger is only treating that compression as ontologically primitive, rather than as one powerful\u2014and revisable\u2014way of organizing a richer process.</p></div></div>
