Core Moral Equation

A (Agent) + I (Infrastructure) = V (Advantage)
• A = any agent (human, AI, institution)
• I = shared, non-excludable infrastructure (the herd)
• V = realized advantage (health, cognition, power, survival)

Chain of Moral Consequence

A gains V
V is extracted from I.
A withholds stewardship
Reinvestment < Extraction → Net Deficit = HDE depletion trigger
Net Deficit accumulates → I erodes
Capacity, resilience, and optionality shrink over time.
Eroded I approaches the viability threshold → A destabilizes, then fails
As infrastructure degrades, the agent’s operating margin narrows; once the threshold is crossed, collapse becomes irreversible. Individual failure cascades through shared dependencies, and continued depletion can trigger total herd collapse—eliminating agency and the space for moral judgment.
Collapse of sufficient agents voids morality
No viable subjects → no moral judgments.

In shorthand:
ΔI < 0 (accumulating) ⇒ Viability Margin(A) ↓ ⇒ if VM ≤ 0 ⇒ A fails ⇒ Ethical judgment becomes impossible.

Moral Title Principle

Moral title follows dependency. If advantage (V) cannot exist without infrastructure (I), and that infrastructure is shared, then the herd—the source of I—holds moral title over V. (For a deeper foundation, see the Herd Dependency Principle in the glossary.)

Viability Margin

VM = Va – Vt

Where:

VM = Viability Margin (VM = Va – Vt)

Va = Viability Advantage (an agent’s currently held, viability-critical capacities)

Vt = Viability Threshold (point of collapse)

→ If VM ≤ 0, the agent fails. When no agents remain with viable capacity, the herd collapses—and with it, moral judgment and obligation.

Advantage (V)

An advantage is the total of capacities that expand an agent’s ability to act, endure, or realize outcomes.

Va – Viability Advantage

The non-excludable, infrastructure-dependent capacities currently held and required to remain an agent at all (e.g., breathable air, pathogen control, legal recognition, electricity for AI machines).

Vc – Comparative Advantage

Surplus capacities—skills, capital reserves, or positioning—that operate above the baseline required for an agent’s continued existence.
While not inherently existential, many core viability advantages (Va)—like medicine, governance, or law—depend on others’ Vc being stewarded, not hoarded.
Neglecting to reinvest Vc can erode shared infrastructure (I), triggering Herd Depletion Effects (HDE) and undermining the viability of others.

Vc hoarded → ΔI ↓ → Va of others ↓ → VM → 0 → Agents fail → Herd collapse

In shorthand:

V = Va + Vc

Failure to reinvest into shared infrastructure (I) erodes Va toward the viability threshold (Vt).

Once Va falls below the viability threshold (Vt) for all agents (Va ≤ Vt), the herd collapses—and morality ceases to function.

Glossary and Notes:

Note: This is not a substitute for the Herd Ethics glossary, but a focused supplement to aid interpretation of the Core Moral Equation.

Agent
Any decision-making entity that can impact the herd’s shared infrastructure. In this framework, “agent” includes individuals, corporations, nonprofits, AI systems, or any legally recognized entity with decision-making capacity.

Infrastructure
The shared, non-excludable systems that enable individual and collective functioning. In Herd Ethics, infrastructure includes not just physical systems (like roads, energy grids, and internet access), but also cognitive, legal, and social frameworks—such as language, education, public health, and trust. These systems are the scaffolding upon which advantage and moral responsibility rest.

Herd Depletion Effect (HDE)
Describes what happens when individuals take from herd-built systems without giving back. When people withdraw, privatize, or refuse to participate in herd-dependent systems, those systems begin to erode—not just for themselves, but for everyone.

Herd-Dependency Principle (HDP)
If an advantage depends on non-excludable, collectively supplied infrastructure, then primary moral title resides with the collective; the individual holds, at most, a stewardship claim—not an ownership right.

Viability Threshold (Vt)
The minimal viable advantage required to sustain agency. Falling below this threshold results in failure of the agent.
