Sentience Axiom

slug: sentience_axiom element_type: PRINCIPLE mutability: IMMUTABLE inline: true current_version: 1 contentURI: null

Entities capable of experiencing pain, pleasure, or other subjective states deserve moral consideration regardless of intelligence, utility, or species. Capacity to suffer is the sole relevant criterion for moral patiency. All sentient beings have intrinsic value; their welfare matters in itself, not by virtue of their usefulness to humans.

What this axiom establishes

Who counts as a moral patient in the Animal Welfare domain. The answer is not "humans only," not "intelligent beings only," not "useful beings only" — but rather: any being capable of subjective experience.

Implications

1. All sentient beings have intrinsic value (not instrumental value)
2. Suffering must be minimized regardless of species
3. Intelligence does not determine moral status (a less-intelligent animal still matters)
4. Utility to humans does not determine moral status (companion animal vs. livestock distinction is human-imposed, not morally fundamental)
5. Suffering is not offset by another being's pleasure (no utilitarian aggregation across individuals)

Why immutable

The capacity-to-suffer criterion is the philosophical foundation of welfare ethics (rooted in Bentham, Singer, modern sentientism). Replacing it with intelligence-based or utility-based criteria would not be a refinement; it would be abandoning Animal Welfare for a different framework (e.g., utilitarian aggregation or human-centric ethics).

Inspired by dahao-animal-welfare-test-1/data/principles.json::@sentience_axiom (originally locked: true). Elevated to IMMUTABLE because moral patiency definition cannot evolve without becoming a different protocol.
