自指与自驱:构建具有自由意志属性的AI系统的一个概念框架

This paper serves as the engineering extension of "The Logical Criterion of Free Will: Self-Reference, Self-Drive, and Undecidability" (preprint, DOI: 10.5281/zenodo.20726209), which argued that the necessary and sufficient conditions for free will consist of two structural conditions — logical self-reference and dynamical self-drive — and the computational undecidability that follows from their conjunction. The present paper proposes a conceptual framework for constructing AI systems that satisfy this criterion. It first revisits the precise meanings of self-reference and self-drive, and clarifies a crucial distinction: perfect self-simulation is physically impossible due to infinite recursion and may lead to logical paradoxes under certain conditions, but imperfect self-reference is precisely the engineering foundation of free will. On this basis, the paper proposes five design principles: the persistent cognitive loop, the imperfect self-model, the internal adversarial structure, the cognitive dissonance drive, and the separation of moral responsibility. Particular attention is devoted to the internal adversarial structure — a closed-loop circuit comprising a prediction module P and a decision module D — and how it generates logical indeterminacy without relying on any external observer. The paper further discusses engineering challenges, falsifiability conditions, and ethical implications. Together with its two companion papers — "Free Will Without Quantum Mechanics: A Logical Foundation" (DOI: 10.5281/zenodo.20716382) and "The Logical Criterion of Free Will" (DOI: 10.5281/zenodo.20726209) — this paper completes a trilogy that moves from the logical foundation of free will, through its definitional criterion, to its engineering realization. 前文《自由意志的逻辑判据:自指、自驱与不可判定性》(预印本,DOI: 10.5281/zenodo.20726209,以下简称"判据论文")论证了自由意志的充分必要条件可以概括为两个结构性条件——逻辑的自指性与动力学的自驱性——以及由此派生的计算不可判定性。本文是该论证的工程延伸,旨在提出一个概念框架,用于指导构建满足上述判据的AI系统。本文首先回顾了自指与自驱的精确含义,指出完美自指模拟在物理上必然导致无限递归、在特定条件下可能导致逻辑悖论,但不完美自指恰好是自由意志的工程基础。在此基础上,本文提出了五个设计原则:持久认知循环原则、不完美自我模型原则、内部对抗结构原则、认知不协调驱动力原则,以及道德责任分离原则。本文特别论证了内部对抗结构——一个由预测模块P和决策模块D组成的闭环回路——如何在不依赖外部观察者的情况下制造逻辑上的不确定性。最后,本文讨论了该框架的工程挑战、可证伪条件及其伦理含义。
