John Stuart Mill - Utilitarianism

📚 In-Depth Notes — Mill, Utilitarianism, Chapter V (Pages 1–6 of your images)

Topic: The Relationship Between Justice and Utility

1. The Problem Mill is Addressing

Mill begins the chapter by explaining that the idea of Justice is one of the biggest obstacles to accepting utilitarianism.

Why? Because:

• People feel justice has a special, almost instinctive authority.

• The feeling of justice seems natural, powerful, and certain — like something built into us by nature.

• This makes people think justice is a separate moral foundation that cannot be reduced to “produce the greatest happiness.”

He wants to show:
👉 Justice is not separate from utility; it's rooted in it.

2. Are Feelings of Justice Natural?

Mill acknowledges:

• Humans naturally feel outraged when something is unjust.

• But having a natural feeling does not make it a reliable moral rule.

  • Example: We have instincts for anger, sexual jealousy, tribal loyalty — but they need guidance from reason.

He says:
👉 The feeling of justice is an instinct, but instincts need to be examined, corrected, and guided by higher reasoning (i.e., utility).

3. The Central Question

Mill wants to figure out:

Is justice:

1. Something with an inherent, special nature — a built-in moral truth?
   OR

2. Just a combination of other moral ideas, presented with emotional intensity?

He leans toward #2.

4. Why This Matters

Because if justice is just a mixture of other moral ideas (like rights, fairness, impartiality), then:
👉 Those ideas could be explained by utility, meaning justice isn’t separate from utilitarianism.

5. Identifying What All Cases of “Justice” Have in Common

Mill begins surveying how people use the words just and unjust. He wants to find a common thread.

He starts listing different forms of injustice.

THE FIVE (so far) FORMS OF INJUSTICE MILL DESCRIBES

1. Violation of Legal Rights

People think it’s unjust to deprive someone of something that legally belongs to them:

• Property

• Liberty

• Anything legally their right

But this category is complicated because:

• Some laws are bad.

• Some laws give people rights they shouldn’t have.

• Even then, people debate if it’s right or wrong to disobey bad laws.

Still:
👉 Legal rights = one major component of what we call justice, though NOT the deepest one.

2. Violation of Moral Rights

Even if the law doesn’t protect something, people believe:

• You can wrongfully violate a person’s moral right.

For example:

• A bad law that harms someone is still unjust because it violates a deeper moral right.

This shows:
👉 Justice is closely linked to rights, especially moral rights.

3. Desert (Deservingness)

Another major idea:
👉 Justice means giving people what they deserve:

• Reward the good

• Punish the bad

Failing to do so = injustice.

This includes:

• General sense: Good for good, bad for bad.

• Specific sense: Reward people who helped you, punish people who harmed you.

People consider this instinctive and emotionally strong.

4. Breaking Faith / Violating Promises

It is universally seen as unjust to:

• Break a promise

• Violate an agreement (explicit or implied)

• Create expectations you don’t keep

This is tied to:
👉 Trust, a huge part of moral and social life.

5. Partiality When You Should Be Impartial

It is unjust to:

• Favor one person over another in situations where fairness requires equality.

Examples:

• Judges

• Hiring for a government job

• Any official decision requiring neutrality

Mill notes:

• Favoritism isn’t always wrong (e.g., helping family), but when you're in a role where impartiality is expected, partiality becomes injustice.

This introduces:
👉 Equality as another essential component of justice.

Key Themes So Far

1. Justice is not one single idea

It is made up of:

• Rights

• Desert

• Promise-keeping

• Impartiality

• Equality

2. Justice is a cluster concept with strong emotional force

Mill argues:

• The strong feelings we have about justice give the illusion that it’s a special, independent moral category.

• BUT these feelings may be natural instinct + social conditioning, not divine truth.

3. Mill wants to show that ALL these aspects of justice can be grounded in utility

His goal is to show:
👉 Justice = the parts of morality that protect the highest and most indispensable forms of human happiness.

Pages ~282–286 (your images)

Theme: Equality, Etymology of Justice, and the Origin of Moral Obligation

1. Equality as Part of Justice — But Interpreted Differently by Everyone

Mill explains that equality is central to many people’s conception of justice, but:

👉 Different people interpret equality differently depending on what they think is “useful” or “expedient.”

Examples Mill gives:

a. People who support equal rights

They believe:

• Equal rights = natural justice.

But in practice:

• They still support huge inequalities in social or economic conditions (e.g., wealth, status, slavery).

He even notes:

• In slave societies, people theoretically say slaves have “rights,” but because enforcing them is seen as inexpedient, the rights are ignored.

b. People who think inequality is useful

These people think:

• Ranks and privileges benefit society.
  Thus inequality = just.

c. Radical leveling ideologies (e.g., communists)

They disagree among themselves:

• Some say goods should be divided equally.

• Others say goods should go to those who need them most.

• Others say rewards should correspond to effort or contribution.

Mill’s point:
👉 Everyone appeals to justice, but what they call "just" depends on what they think is best for society (i.e., utility).

This supports Mill’s thesis:
Justice is not a separate moral idea — it tracks people’s beliefs about what promotes general happiness.

2. Mill Looks at Etymology to Clarify What Justice Originally Meant

Mill turns to the history of the word "justice" to understand its root meaning.

Key Findings:

• In many languages, the word for justice is historically tied to law.

• Latin justum, jus, jussum → ideas of what is ordered, prescribed, commanded.

• Greek dikaion → originally linked to:

  • The method/manner things “ought” to be done

  • What authorities enforce

• German recht (source of right) meant:

  • Straight, correct, proper (physical straightness)

  • NOT originally law—but the connection to law formed later.

Mill’s interpretation:
👉 Historically, justice = lawfulness (following established rules), and injustice = violating those rules.

But then societies evolved:

• Some laws were seen as bad.

• Some laws violated “proper” moral standards.

• People started to see unjust laws as possible.

• So justice became tied not just to law, but to what laws ought to be.

Thus:
👉 Justice shifted from obedience to law → to the idea of ideal, moral law.

This strengthens Mill’s point:

• Justice is tied to social protection and moral expectations, not some metaphysical essence.

3. Even When Law Isn’t Involved, People Still Use the Language of Justice

Mill argues that even in areas not governed by law, people still think:

• Certain actions are just or unjust.

• Wrong acts “deserve punishment.”

This shows:
👉 Justice involves the idea of punishment, whether legal or social.

For example:

• If someone acts unfairly in private life, we still feel they ought to be punished — even if the law won’t do it.

So justice includes:

• Moral blame

• Social disapproval

• Personal conscience

This links justice to:
👉 A natural human desire to see wrongdoing punished.

4. Core Turning Point: Justice = Wrong + the Idea of Punishment

Mill identifies the key distinction between justice and other morality:

✨ Justice is the part of morality where society thinks punishment is appropriate. ✨

In other words:

• Some moral failures make you say “Ugh, that was disappointing.”

• But injustice makes you say:
  “That person ought to be punished for that.”

This is crucial because:
👉 The demand for punishment comes from a strong emotional instinct (resentment, vengeance, self-defense), which Mill will later show can be grounded in utility.

5. The Difference Between Justice and Other Moral Duties

Mill explains:

Duties of “perfect obligation”

• These involve a specific person who has a right to something.

• They can be demanded from you.

• They justify punishment if violated.

Examples:

• Keeping promises

• Not stealing

• Giving someone what they’re entitled to

👉 These are justice.

Duties of “imperfect obligation”

• Morally good, but:

  • No one can claim them as a right.

  • No specific punishment fits.

Examples:

• Charity

• Kindness

• Being helpful

👉 These belong to general morality, not justice.

Thus:
👉 Justice = moral obligations that correlate to someone else’s rights.

This becomes Mill’s definition.

6. Justice Always Implies:

1. A wrong act

2. A specific person who is wronged

3. A claim they could demand

For example:

• Taking someone’s property

• Breaking faith with someone

• Treating someone worse than they deserve

Even treating someone better than others can be unjust:
👉 Because it wrongs the others who get less than they are entitled to.

So:
👉 Justice focuses on rights and the rightful claims of specific individuals.

7. Why This Helps Mill

He’s setting up for his big claim:

👉 The reason justice feels so strong and important is because it protects things essential to human happiness:

• rights

• security

• consistency

• fairness

• trust

• protection from harm

Thus:
Justice is not separate from utility — it is utility in its most essential and socially protective form.

Pages ~287–291

Theme: The Psychological Origin of Justice, Punishment, Rights, and Security

1. Mill’s Big Question Now:

Where does the feeling of justice actually come from?

He asks:

• Is it an instinct?

• A product of reason?

• A special moral faculty?

• Or does it grow out of something simpler (like our experiences of “expediency” or usefulness)?

Mill’s answer:
👉 The feeling of justice does NOT arise from an idea of utility…
…but everything moral in the feeling depends on utility.

2. The Two Essential Ingredients in the Sentiment of Justice

Mill repeats his core structure:

Justice = (1) desire to punish + (2) belief that someone specific was wronged

Meaning:

• Justice always involves punishment and rights.

He wants to explain:
👉 Where does the impulse to punish come from?

3. The Desire to Punish Comes From Two Natural Sources

Mill says humans have two deeply natural instincts:

a. Self-defense

• All animals retaliate when harmed or threatened.

• It is biologically universal: even animals attack what hurts them or their young.

b. Sympathy

• Humans can feel the pain of others.

• We don’t just protect ourselves: we protect anyone we sympathize with.

• Humans sympathize more broadly than animals:

  • not only family

  • not only friends

  • but strangers

  • entire groups

  • entire humanity

  • even sentient beings in general

This combination produces:
👉 A spontaneous desire to punish people who harm ourselves or those we sympathize with.

This becomes the emotional root of justice.

4. Human Intelligence Expands These Feelings Much Further

Because humans think abstractly:

• When society is threatened, we feel personally threatened.

• We link our own safety with the safety of the group.

• We start to feel resentment not only for personal injuries, but for injuries to society as a whole.

Thus:
👉 We punish wrongdoing even when it does not affect us personally.

This is crucial:
Justice becomes social, not just personal.

5. Punishment as the Foundation of Justice

Mill says:

The desire to punish is the primitive core of justice.

But punishment only becomes moral when:

• The impulse to punish is subordinated to social good, not personal revenge.

Meaning:
👉 A moral person doesn’t resent harm merely because they are hurt.
They resent it because it violates a general rule meant to protect society.

So the moral version of the feeling requires:

• Restraint

• Reflection

• Considering what’s best for society

6. Mill says: we don’t call resentment “moral” unless…

A person asks:

“Is this act actually wrong in general? Should anyone be punished for this, or am I just personally annoyed?”

If resentment is guided by:

• principle, not personal irritation

• consideration of society, not just oneself

👉 Then it becomes a moral feeling — the sentiment of justice.

7. Mill Brings in Kant

Mill points out that even Kant’s famous moral rule:

“Act only according to the rule that you would want as a universal law”

…implies concern for:

• the collective interest of humanity

• what benefits all rational beings

This supports Mill’s idea:
👉 Even deontologists secretly rely on the idea of collective good (utility) when defining justice.

8. RECAP — Mill’s Definition of Justice (Major Section)

Mill summarizes:

Justice requires:

1. A rule of conduct

   • A rule believed to be necessary for human good.

2. A sentiment that sanctions the rule

   • A desire to punish violations.

And justice always includes:

• A specific person who has been wronged

• A right that has been violated

• A demand for punishment

9. Mill Explains What a “Right” Is

A right =
👉 A valid claim society should protect.

Examples:

• If someone owns property by law → they have a right to it.

• If someone earns money through fair competition → society should protect their ability to earn it.

• If someone has a legal entitlement (like interest on stock) → they have a right because society has promised it.

Crucially:
👉 A person does NOT have a right to things society has not promised.

Example Mill gives:

• A man earns £300 a year → he has no right to keep that income if society hasn’t guaranteed it.

• But if society does guarantee it, then he has a right.

Thus:
Rights depend on:

• social protection

• social recognition

• utility (what best maintains safety & order)

10. Why Rights Feel So Intense

This is one of the most important paragraphs in the whole chapter.

Mill says rights feel so strong because:

a. Rights protect security

Security is:

• the “most vital of interests”

• the foundation of all happiness

• more important than any single material good

Why?
👉 Without security, no one could enjoy any pleasure or plan for the future.

b. Security requires strong social protection

Because everyone depends on security:

• society must enforce rights intensely

• feelings around rights become extremely strong

Thus:
👉 Rights feel absolute because they protect the absolute necessity for human happiness: safety.

11. Why Justice Feels Different from General Morality

Justice feels:

• more powerful

• more absolute

• more emotional

Because:
👉 It protects security — the foundation of human existence.

This is why:

• violating rights feels worse than other wrongs

• justice seems “higher” than utility

• people think justice is innate, not utilitarian

But Mill says:
All this intensity is actually rooted in utility — specifically the utility of protecting security.

12. Mill Returns to His Main Thesis

He says:
If justice were a separate moral faculty unrelated to utility, it would be:

• obvious

• consistent

• unchanging

But it isn’t.

Instead:

• People disagree massively about what is “just”

• Different societies have different ideas of justice

• Individuals contradict themselves about justice

This proves:
👉 Justice is not a separate, innate moral standard.
👉 It is part of utility, shaped by experience and social needs.

Pages ~292–296

Theme: Conflicts in Justice → Contract Theory → Proportional Punishment → Disputes About Fair Pay and Taxation → Mill’s Final Argument for Why Justice = Utility

1. Mill Presents Conflicting Intuitions About Punishment

He shows that people strongly disagree on what is just:

View A: It is just to punish for the offender’s own good

• Some say punishment can benefit the criminal by reforming them.

• Therefore, punishment can be justified even if no one else is harmed.

View B: It is unjust to punish someone “for their own good”

• Critics call this despotic and tyrannical.

• They argue adults should decide their own good.

• Punishment is justified only to prevent harm to others — self-defense.

View C (Mr. Owen): Criminals shouldn’t be punished at all

Because:

• Their character was shaped by circumstances they didn’t choose.

• Education, environment, and social conditions made them who they are.

• Therefore, they aren’t morally responsible.

Mill says all three positions sound plausible when isolated.

Why?
👉 Because each position relies on a legitimate principle of justice.

2. Why All Three Conflicting Views Sound “Right”

Mill argues:

Each theory appeals to a different maxim of justice, each of which has real authority:

Theory 1 (Punish for their own good)

Appeals to:
👉 The injustice of “sacrificing” someone for the good of others without consent.
So forcing them to behave well “for society’s sake” is unjust — but punishing them to help them avoids that.

Theory 2 (Punish only to prevent harm)

Appeals to:
👉 The acknowledged right of self-defense.
You may prevent people from harming others, but not meddle in their personal good.

Theory 3 (Never punish what the person cannot help)

Appeals to:
👉 The principle that one cannot be punished for what is not within their control.

The problem:
👉 Each principle is valid, but they contradict each other.

Thus:

• Everyone can defend their view of justice.

• No one’s “justice” can be applied universally without violating another equally binding maxim.

This shows:
👉 Justice is not a single innate rule — it’s a cluster of useful moral ideas that can conflict.

3. The “Social Contract” Is Invented to Escape the Contradictions

To solve the contradictions, societies invented the idea of:

A fictional social contract

Everyone supposedly agreed:

• To obey laws

• To accept punishment for breaking them

• To give legislators the right to punish

This contract made punishment seem “just” because:
👉 It was done with the supposed consent of the governed.

Mill says this was basically:

• A convenient myth

• Used to make the system feel morally justified

He says:
👉 Even if it were true, it wouldn’t actually settle the contradictions of justice.

4. The Maxim: “No wrong is done to someone who consents” (volenti non fit injuria)

Mill shows how courts often use this principle:

• If someone consents to a risk or harm, it's not unjust.

• This principle entered law because it was “helpful,” not because it’s fundamentally correct.

BUT:

• Even courts can’t apply it consistently.

• They still void contracts made under fraud or misinformation.

• They still protect people when consent is doubtful.

This shows:
👉 Even legal “rules of justice” are improvised, inconsistent, and shaped by practical needs.

5. People Strongly Disagree About the Purpose of Punishment

Even when everyone agrees punishment is legitimate, they disagree on:

How punishment should be distributed:

View 1:
👉 Punishment must be proportional to the moral guilt of the offender.
(“Eye for an eye” / lex talionis)

View 2:
👉 Punishment should be whatever best deters crime, independent of moral guilt.

These two ideas are totally incompatible.

Mill highlights:

• The emotional appeal of “an eye for an eye”

• How natural it feels to return harm in equal measure

• But also how many reject this view as outdated

Again:
👉 Both sides feel morally justified.

6. Another Example: Fair Wages (Reward Based on Talent/Skill)

Mill uses co-operative industry as an example.

Two opposing claims of justice:

Side A: Equal Pay

Arguments:

• People with superior talents already benefit enough via:

  • admiration

  • social influence

  • personal satisfaction

• Inequalities of talent are undeserved.

• Thus society should compensate the less fortunate.

• Paying the talented more only worsens inequality.

Side B: Pay Proportional to Contribution

Arguments:

• More skill means more valuable labor.

• Society gains more from a skilled worker, so he deserves more.

• To deny him greater remuneration is “robbery.”

• Equal pay regardless of effort discourages productivity.

Mill’s point:
👉 Both positions are compelling and genuinely rooted in justice.
Justice here has two sides, equally legitimate but impossible to harmonize.

Thus:
👉 Only social utility can decide between them.

7. The Same Pattern Occurs in Taxation Debates

Mill shows people disagree completely on what just taxation is:

View 1: Proportional taxation

Everyone pays the same percentage of their income.
→ “Fair because it’s numerically proportional.”

View 2: Graduated taxation

The rich pay a higher percentage.
→ “Fair because rich citizens can spare more.”

View 3: Poll tax / equal head tax

Everyone pays the same amount.
→ “Fair because everyone gets equal protection from the law.”

Mill says all of these feel “just” to someone.

Each view reflects:

• A different principle

• A different interpretation of fairness

• A different idea of rights

And none can be proved “just” without appealing to:
👉 Utility — the general good of society.

8. Mill Returns to His Central Question: Is justice more sacred than utility?

He asks:

• Is the distinction between the “just” and the “expedient” just an illusion?

• Are people wrong to think justice is higher than policy?

He answers:
👉 No — justice is more sacred.
👉 But only because utility makes it sacred.

Justice = the part of morality dealing with:

• Vital human interests

• Security

• Rights

• Protection from harm

Because these are the most essential conditions of human happiness:
👉 Justice becomes the most binding, sacred part of morality.

NOT because:

• Justice is innate

• Justice is absolute

• Justice comes from a special moral faculty

But because:
👉 Of all moral rules, rules of justice are the most important for human well-being.

This is the core of Mill’s argument.

9. Mill’s Big Conclusion (Beginning): Justice = Utility Protecting Vital Interests

Mill now sets up his conclusion:

• Justice refers to moral rules that protect the fundamental conditions of human life.

• These rules forbid harming others or violating their freedom.

• These rules are absolutely essential for:

  • social peace

  • mutual trust

  • human cooperation

  • security

  • survival

Thus:
👉 These rules create the strongest moral obligations.
👉 They feel sacred because they protect everyone’s deepest interests.

So:
Justice is the name we give to moral rules with the highest utility — those essential to security.

1. Competing Views on Punishment

Mill reviews several contradictory theories people hold about when punishment is just:

View 1: Punish for the criminal’s own good.

• Some argue punishment is justified if it benefits the wrongdoer.

• Mill says: this is paternalistic and controversial.

View 2: Punish only to prevent harm to others.

• Others claim punishing adults “for their own good” is despotism.

• They argue punishment is justified only as self-defense — to prevent danger to society.

View 3: Punish only if the wrongdoer is responsible for their character.

• Robert Owen’s position:

  • Criminals are shaped by circumstances.

  • They did not choose their character.

  • Therefore, punishment is unjust.

Mill’s point:
All three arguments sound plausible if you assume justice is only about abstract principles.
But once you dig deeper, they conflict.

2. Why These Views Conflict

Each argument draws on a different widely accepted principle of justice:

1. Do not sacrifice one person for others without consent.

2. Respect autonomy—don’t force one person to live by another’s idea of “good.”

3. It’s unjust to punish people for what they cannot help.

Each principle sounds true, but they collide when applied to real cases.

This shows:
➡ “Justice” is not self-evident or consistent. It contains multiple maxims that contradict each other.

3. Why People Invent “The Social Contract”

To solve contradictions, people created the idea that:

• Everyone implicitly agreed long ago to obey society’s laws.

• Therefore punishment = consented to.

Mill says: this is historically and philosophically fiction, created to escape the inconsistency.

4. Punishment and the Maxim “Volenti non fit injuria”

(“No injury is done to the person who consents.”)

• Courts sometimes rely on this idea to justify obligations or transactions.

• Mill argues:

  • It is used inconsistently.

  • Even voluntary agreements can be invalidated if based on fraud or mistake.

  • So consent is not the ultimate foundation of justice.

5. Retributive Justice (Lex Talionis)

“An eye for an eye” appeals strongly to human nature.

Why?

• Humans feel primitive, instinctive resentment when wronged.

• When punishment fits the crime (repayment in kind), people feel satisfaction.

• Mill emphasizes:

  • This feeling is natural, but not necessarily moral.

  • It must be governed by society’s interest.

People disagree:

• Some think punishment should match moral guilt.

• Others think punishment should focus solely on deterrence.

This shows again that justice has multiple competing standards.

6. Dispute Over Rewards: Should Talent Earn Higher Pay?

Mill gives the example of a cooperative association debate:

Side A: No — equal rewards for all

Arguments:

• Ability differences are not earned; they shouldn’t justify more social goods.

• Highly talented already enjoy:

  • Admiration

  • Influence

  • Internal satisfaction

• Society should compensate those less advantaged.

Side B: Yes — more talent deserves more reward

Arguments:

• Efficient workers contribute more to society.

• Justice means rewarding proportional contribution.

• Denying extra reward is like stealing their contribution.

Mill’s conclusion:
Both sides appeal to justice, but arrive at opposite answers.
➡ Only social utility can decide.

7. Justice in Taxation: Equality vs. Equity

Conflicting ideas of justice reappear in taxation:

View: Equal percentage tax (proportional).

• Everyone pays a share proportional to income.

View: Graduated tax (progressive).

• The wealthy should pay a higher percentage.

View: Equal sum for all (poll tax).

• Since law protects everyone equally, everyone should pay equally.

Mill shows:
➡ All three claim to be “just,” yet they contradict each other.
➡ Only utility can evaluate which system benefits society most.

8. Justice vs. Expediency

Mill asks:
Is the difference between justice and ordinary expediency real or imaginary?

His answer:
Yes, the distinction is real.
Justice concerns rules society considers absolutely essential for security.

Justice =

• Protecting people from harm

• Ensuring fair treatment

• Enforcing rights

These are tied to deep, strong emotions, especially resentment against those who violate rights.

This intensity makes justice seem more sacred than policy.

9. Justice = Utility About Security

Mill’s core argument:

Justice is not separate from utility.

It’s the part of utility that concerns:

• Security

• Protection of rights

• Preventing harm

• Maintaining trust

These are the most vital moral interests because:

• Without security, no one can plan, work, or enjoy any benefit.

• Even momentary insecurity destroys happiness.

Thus:
➡ Justice = the most important subset of utilitarian morality.

10. Why Justice Feels Different From Other Morality

The feeling of justice involves:

• Resentment against wrongdoing

• Sympathy for the victim

• Intelligence that recognizes society depends on these rules

This combination gives justice:

• A sharper sense of obligation

• Social urgency

• The feeling of being absolute and non-negotiable

Justice rules protect:

• Bodily security

• Property

• Contracts

• Freedom

• Expectations

• Social cooperation

These are the foundation of civilization.

11. Core of Mill’s Theory of Justice

At the end, Mill concludes:

Justice = rights + obligations grounded in social utility, especially security.

• Justice feels unique because the interests it protects are uniquely important.

• The strength of our emotions surrounding justice is explained by:

  • Resentment

  • Sympathetic identification

  • The social need for security

So the sentiment of justice is NOT mysterious or metaphysical.

It is a natural human emotion, moralized by social utility.

12. Final Conclusion

Justice is:

• Not an independent moral category.

• Not derived from abstract rights.

• Not grounded in social contract.

• Not based solely on retribution or consent.

Justice is:
⭐ The most vital and sacred part of utilitarian morality,
because it protects security, the base of all human happiness and cooperation.

Justice rules must be:

• Clear

• Impartial

• Strongly enforced

• Prioritized above other moral rules

But ultimately, their authority comes from:
➡ Their indispensability to human well-being.
