Virtual Virtue: Ethics in Parity VR

Picture a virtual world that feels exactly like ours, with none of its material limits. There, ethics based on duty or outcomes falls apart. Only virtue holds.

Introduction  The premise

Suppose virtual reality reaches parity with the real world.

“Coffee, the experience of its taste, air, the way it fills your lungs, all of these experiences will feel exactly the same in and out of the machine.”Virtual Virtue, Introduction
Experiential parity
Once you're inside, nothing you can experience tells it apart from the real world.
No material constraints
Anything can be built, owned or experienced. Scarcity is gone.
Needs already met
Shelter for you and the machine, and everything required to sustain life, are taken care of outside.

Question one

What is the ideal ethical system for life inside a Parity VR?

Question two

What does that answer tell us about ethics in the material world today?

Sections 1.4 – 1.6  The collapse

Take away the material world and two ethical systems fold into the third.

Drag the slider from the world we live in to a Parity VR. Watch what happens to consequentialism and deontology once nothing is scarce and no one else can be harmed.

Virtue EthicsCultivates character
ConsequentialismJudges outcomes
DeontologyFollows duty

Material world

All three systems stand on their own. Consequences land on other people, property can be stolen and promises bind.

Consequentialism

Right action is whatever brings the best consequences.

Leans on the material world for

Consequences that reach other people and things.

Inside Parity VR

Inside the simulation, there is only one thing experiencing consequences: you. With no account of which good to aim for, it drifts toward measuring pleasure, even dopamine levels. To reach the highest good it has to borrow virtue ethics' structure.

BecomesFulfillment outcomes

Deontology

Right action is whatever duty and the moral law require.

Leans on the material world for

Ownership, promises and real harm to real people. Kant's test against stealing only works where things can be owned.

Inside Parity VR

I cannot steal in a Parity VR. The murderer-at-the-door dilemma goes inert. Only the duty to treat humanity as an end survives, and on its own that can't tell you how to live.

BecomesInternal duty: rules kept to build character

Virtue Ethics

Right action is what a flourishing, excellent person would do.

Leans on the material world for

Very little. It needs knowledge of the human animal and its aim, eudaimonia.

Inside Parity VR

It keeps its structure. Aristotle's chain of ends still works when nothing is scarce. You are the goal; your becoming is the goal.

BecomesThe framework that holds

Sections 1.1 – 2.3  The argument, in order

From Descartes' dream to a design brief for VR.

  1. 1.1

    A Parity VR carries real ethical weight

    We can't rule out that we're already in a simulation, and whatever could simulate the world could underlie ours too. So a Parity VR deserves the same ethical seriousness as the world we treat as real.

    DescartesChalmers
  2. 1.2

    Action inside it is real action

    Nozick's experience machine is passive: you only think you're writing the novel. In a Parity VR a sober mind makes real choices, and a book written there has real words on the page.

    Nozick
  3. 1.3

    You may be the only person inside

    The paper takes the single-actor view. If AI avatars can replicate human interaction, they can serve as means to flourishing whether or not they are conscious.

    Aristotle
  4. 1.4

    Consequentialism morphs

    With one person experiencing every consequence and no account of the good, outcomes collapse into fulfillment. Reaching the highest good means taking on virtue ethics' aim.

    Mill
  5. 1.5

    Deontology morphs

    Without ownership or material harm, Kant's rule-finding machinery has nothing to work on. Duty turns inward and becomes a practice of building moral character.

    Kant
  6. 1.6

    Virtue ethics holds

    Every end points to a higher one until you reach eudaimonia, which is chosen for its own sake. That chain needs no scarcity to work.

    Aristotle
  7. 1.7

    Build it as a game

    Games have goals, participants and rules. In a Parity VR the goal is already known. Every rule should be a building block toward flourishing.

    SuitsTavinor
  8. 2.1

    Philosophy has done this before

    Rawls strips away people's material circumstances behind the veil of ignorance to learn about justice. Parity VR strips away external material constraints to learn about ethics.

    Rawls
  9. 2.2

    VR ethics needs recalibrating

    Today's debate centers on preventing harm and writing rules. Designers, developers, policymakers and users should ask a more basic question: does this experience help people flourish?

    VR design
  10. 2.3

    Two of the three systems are conditional

    Deontology and consequentialism draw their structure from material conditions. Virtue ethics works in any conditions, which puts it closer to a priori knowledge.

    Conclusion

Section 1.2  Answering the experience machine

Nozick's argument is sound. His machine just isn't a Parity VR.

In 1974 Robert Nozick asked whether you would plug into a machine that gave you any experience you wanted. He gave three reasons not to. Each depends on a passive machine that only makes you think you're doing things.

Nozick's objectionThe Parity VR reply
“We want to do certain things, and not just have the experience of doing them.”Anarchy, State, and Utopia

In a Parity VR you actually do them. Write a great book in the simulation and the words are on the page. The meaning of those sentences doesn't evaporate because they're digital.

“We want to be a certain way, to be a certain sort of person.”Anarchy, State, and Utopia

A sober participant making autonomous choices can become kind or brave. With no material limits on experience, there is more room to develop character.

Plugging in “limits us to a man-made reality.”Anarchy, State, and Utopia

This is his strongest point. Still, we can't know our own world isn't already a simulation, and inside a Parity VR the question is what has value, which is different from what is materially real.

Section 1.7  How to apply it

“The game is a means, you are the player, and the end is you becoming yourself, to the absolute maximum.”
Games have goalsEudaimonia
Games have participantsYou
Games have rulesBuilding blocks of flourishing

Survival is the oldest game there is. Everyone alive today descends from an unbroken line of players who finished it. Material constraints shaped that game, and many of them limit experience without helping anyone flourish.

A Parity VR lets us design the game on purpose. The thesis doesn't claim to know the rules yet. It claims they all have to serve one end.

Sections 2.2 – 2.3  Why it matters now

A thought experiment with a brief for today's VR.

Parity VR may never arrive. Headsets are already pushing to blur the line between the virtual and the physical, and policy, law and ethics tend to lag behind technology.

Most ethical discussion of VR today is about preventing harm or setting rules. Those still matter. The thesis argues designers, developers, policymakers and users should start from a more basic question.

Conditional

Deontology & Consequentialism

Their structure comes from material conditions. Their footing is a posteriori.

Unconditional

Virtue Ethics

Works with or without material constraints. Closer to a priori knowledge, like arithmetic.

Ask of any virtual experience

Does this help the people inside it flourish? What kind of person does it make me?

Section III  Objections

The hard questions, answered.

3.1

With no limits, what stops a slide into hedonism?

Under consequentialism or deontology alone, nothing would. Consequentialism can't say what the good is, so it can lead toward pleasure instead of fulfillment. Deontology sets a few strict rules and permits most hedonism beyond them.

Virtue ethics resists it by design. For Aristotle pleasure is fleeting and a by-product of other activity. Eudaimonia is complete and self-sufficient, a way of being rather than a feeling.

3.2

Won't knowing it's a simulation drain life of meaning?

Some meaning goes, especially in material pleasures and accomplishments. Intellectual pleasures keep their weight. Learning about yourself, about reason and about the human animal still produce meaning, and a world where you can play endlessly toward eudaimonia makes self-knowledge more reachable.

3.3

Is it ethical to treat AI avatars as means?

Yes. We can't be certain other humans are conscious, and we would likely never know whether an avatar is. Treating avatars well can still be right, for the reason Kant gives about animals: cruelty to them damages the humanity in yourself.

So you treat virtual agents in the way that preserves your humanity and serves your flourishing. That standard doesn't depend on whether they are moral agents.

About the author

John McShea studied philosophy at Middlebury College, where Virtual Virtue: Ethics in Parity VR was his honors thesis. He is a member of Phi Beta Kappa.

His work sits where virtue ethics meets the design of immersive technology. The thesis draws on Aristotle, simulation theory and the philosophy of games to argue that virtual worlds should be built for human flourishing.

He is also the founder of Nodebox, where he built the backend. Nodebox lets people send their work, files and reasoning to teammates straight from an AI chat, so a teammate's own AI can pick it up and continue.
