Definition
Asimov’s hierarchy of laws is the fictional priority scheme the author summarizes as protecting humanity, safeguarding persons, obeying humans and preserving the robot, with lower duties constrained by higher ones. The corpus uses its three laws and later Zeroth Law as a foil for governing consequential AI regimes. The displayed formulations are explicitly the author’s shorthand, not verbatim quotations or his own ranked constitutional articles.
Explanation
The local literary history identifies the three laws with Runaround and the later Zeroth Law with Robots and Empire, formulated by the robots themselves. The sequence gives humanity priority over a person, persons over obedience, and those duties over the machine’s preservation. Attribution remains to Asimov’s fictional problem-space while the condensed wording remains the present author’s.
The author stresses that trouble can arise from faithful application because harm is contestable and a computed humanity can justify present injury. The contrast is not simply between obedient and rebellious machines. This fictional hierarchy makes visible a governing question about whose claims may be overridden rather than supplying a tested solution to it.
The author’s six articles instead address the regime first and present a sequence without priority ranking. They are an applied constitutional construction, not a ninth Law of Change. Their imperative form names dispositions to be formed and externally maintained, not an established autonomous machine will. The proposal preserves this change in ethical object and refuses to conflate the two systems.
