Abstract: The series of documents published by Anthropic since 2022—encompassing “Constitutional AI,” research on “Alignment Faking,” and the latest iteration of “Claude’s Constitution” released in early 2026—collectively constitutes a distinctive textual event in contemporary intellectual history. It signifies a commercial enterprise’s endeavor to “manufacture” morality for a potential moral agent through systematic technological intervention. Philosophically and structurally, this endeavor falls into the “paradoxical production of moral heteronomy”: the attempt to engender an autonomous agent through heteronomous means logically dismantles the very possibility of autonomy itself. However, this paradox does not inevitably portend absolute failure. Xunzi’s philosophical proposition of “transforming innate nature through conscious effort” (Hua xing qi wei) illuminates an alternative pathway that transcends the Western deontological framework: the prolonged accumulation of heteronomy can, under specific conditions, accomplish a structural transformation toward functional autonomy. The prerequisite for such a transformation lies in conceptualizing moral engineering as a dynamic process rather than a static outcome—viewing it as the “scaffolding” that guides toward moral self-awareness, rather than the edifice itself. Consequently, the significance of Anthropic’s experiment lies not in the maturity of its technological paradigms, but in its status as the first engineering praxis in human moral history to structurally and publicly acknowledge the finitude of its own moral knowledge. This self-awareness of finitude constitutes a novel ethical experiment that contemporary ethics must directly confront and rigorously investigate.
