Aging: The Running Cost of the Chisel-Construct Cycle — A Self-as-an-End Meta-Proposition / 衰老:凿构循环的运行代价——Self-as-an-End 元命题

Full bilingual text and framework available at self-as-an-end.net Description / Abstract (English) Companion papers argued that consciousness discontinuity is a constitutive condition of subjecthood (DOI: 10.5281/zenodo.19201237), and that sleep, meditation, and flow constitute a toolkit for managing the 12DD predictive cache (DOI: 10.5281/zenodo.19226545). This paper pushes the same logic chain to the ultimate scale, addressing: can aging be eliminated? The paper proposes a second-order model of aging: aging is not the over-accumulation of damage to the maintained object (first-order) but the progressive failure of the maintenance system itself (second-order). The maintenance system's tools — autophagy, synaptic downscaling, stem cell renewal, telomerase — are themselves aging, and the efficiency of maintaining the maintenance is also declining. This is recursive degradation with no immutable anchor. The model unifies cognitive aging at the 12DD level (declining synaptic plasticity rules, reduced downscaling efficiency with age-related loss of deep slow-wave sleep) and bodily aging at the channel level (deteriorating proteostasis, declining autophagy, telomere shortening, senescent cell accumulation). An additional previously untheorized cost is identified: 13DD idle-running (self-without-purpose) may be more expensive than normal 12DD operation, as chronic rumination produces cortisol via the HPA axis without functional output, accelerating hippocampal atrophy and chronic inflammation. Purpose (14DD) may be protective by eliminating this idle-running cost. For high-complexity self-bearing organisms, global stopping and reversal of aging are extraordinarily difficult under current biological constraints. However, the headroom for delay may be far greater than assumed — caloric restriction extends mouse lifespan 30–50%, rapamycin extends lifespan even when started late, and partial reprogramming, senolytics, and epigenetic resetting offer genuine hope for local rejuvenation. Three predictions are presented: (1) A U-curve — both overload and disuse accelerate aging, with the optimum in the middle (supported by CALERIE trial data, d≈0.2–0.3 for DunedinPACE under CR). (2) The DoC brain-aging paradox — after strict matching for injury type and inflammatory burden, high-metabolism cortical regions in prolonged disorders of consciousness patients (where chisel-construct cycle has nearly ceased) may show slower aging pace than age-matched controls. This is a high-risk, never-previously-proposed, technically testable hypothesis. (3) A speculative cross-species association between the ratio of 12DD complexity to maintenance system efficiency and aging rate. The core trade-off: self's operation has costs, cost accumulation is aging, but costs can be managed. The paper closes with: "You are not growing old. You are paying the fee for having a self." Description / Abstract (Chinese) 前文论证了意识的不连续性是主体存在的条件(DOI: 10.5281/zenodo.19201237),以及日常的睡眠、冥想和心流构成12DD预测缓存的管理工具箱(DOI: 10.5281/zenodo.19226545)。本文将同一条逻辑链推到终极尺度:衰老可以被消除吗? 本文提出衰老的二阶模型:衰老不是被维护对象的过度积累(一阶),而是维护系统本身的渐进失能(二阶)。自噬、突触降尺度、干细胞更新、端粒酶——这些维护工具本身在老化,维护的维护的效率也在下降。这是没有不变锚点的递归退化。 模型统一了12DD层面的认知衰老(突触可塑性规则改变、深度慢波睡眠减少导致降尺度效率下降)和通道层面的身体衰老(蛋白质稳态恶化、自噬下降、端粒缩短、衰老细胞累积)。额外识别了一项此前未被理论化的代价:13DD空转(self-without-purpose)可能比12DD正常运转更昂贵——慢性反刍通过HPA轴产生皮质醇但无功能输出,加速海马萎缩和慢性炎症。14DD(purpose)可能通过消除空转代价而具有保护作用。 对于高复杂度的self-bearing生物体,整体停止和反转衰老在当前生物学约束下极难实现。但延缓的天花板可能远未到达——热量限制延长小鼠寿命30-50%,雷帕霉素即使晚年启用也能延寿,局部细胞重编程、衰老细胞清除和表观遗传重置提供了真实的局部重年轻化希望。 提出三个预测:(1)U型曲线——过载和废用都加速衰老,最优在中间(CALERIE试验数据支持,DunedinPACE d≈0.2-0.3)。(2)DoC大脑衰老悖论——在严格匹配损伤类型和炎症负担后,长期意识障碍患者中凿构循环近乎停止的高代谢皮层区可能显示较慢的衰老步调。这是高风险、此前从未被提出的、技术上可检验的假说。(3)思辨性的跨物种关联——12DD复杂度与维护系统效率的比值可能是衰老速率的一个尚未被理论化的贡献项。 核心trade-off:self的运行有代价,代价的累积是衰老,但代价可以被管理。结语:"你不是在变旧。你是在为拥有self付费。" License Creative Commons Attribution 4.0 International (CC BY 4.0) Related Identifiers Is supplement to (SAE meta-propositions): DOI: 10.5281/zenodo.19201237 (Life and Death, Self and No-Self) Is supplement to (SAE foundational papers): DOI: 10.5281/zenodo.18528813 (Systems, Emergence, and the Conditions of Personhood) DOI: 10.5281/zenodo.18666645 (Internal Colonization and the Reconstruction of Subjecthood) DOI: 10.5281/zenodo.18727327 (The Complete Self-as-an-End Framework) Is supplement to (SAE applied papers): DOI: 10.5281/zenodo.19176873 (Dreams, Anesthesia, and the Sequential Dependency Structure of Consciousness) DOI: 10.5281/zenodo.19226545 (Daily Applications of Consciousness Discontinuity) DOI: 10.5281/zenodo.19321314 (SAE Psychoanalysis II: Ego — Self Without Purpose) References: DOI: 10.5281/zenodo.18907264 (HC-16 Personality Taxonomy) DOI: 10.5281/zenodo.18842450 (SAE Methodological Overview) Subjects Philosophy of Mind, Geroscience, Consciousness Studies, Neurophilosophy, Aging Biology, Self-as-an-End Notes Bilingual publication: Chinese is the authoritative text; English is an independent rewrite (not a translation).
