Morality vs Ethics — What's the Difference?

Foundations
🧠 Memory Hook
Ethics Studies Morality

Morality = the actual rules of conduct a society lives by.
Ethics = the philosophical study of those rules — asking why they exist and whether they're justified.

Think of it this way: Morality is the rulebook. Ethics is the analysis of the rulebook.

Four Features of a Moral System

Must Know
🧠 Mnemonic — PIRI
People Inside Reason Impartially

Public · Informal · Rational · Impartial

👁️

Public

Everyone in the society must know what the rules are. No hidden codes.

🤝

Informal

No formal judges or courts. Unlike law, morality has no authoritative enforcers.

🧠

Rational

Based on logical reason accessible to ordinary people — not special or privileged knowledge.

⚖️

Impartial

Rules apply equally to everyone. No favouritism for any group or individual.

03

The 4 Core Ethical Principles

Principles
🧠 Mnemonic — BLAJ
Be Less Autocratic, Judge!

Beneficence · Least Harm · Autonomy · Justice

💚

Beneficence

Do what is right and good. Prioritise doing good — the "do good first" principle.

🩹

Least Harm

When no great option exists, choose the option that harms the fewest people the least.

🗽

Respect for Autonomy

Allow people to make their own decisions about their own lives — they know their lifestyle best.

⚖️

Justice

Actions should be fair to all those involved — no unjust advantages or burdens.

04

What All Ethical Theories Have in Common

Shared Core
🎯

Right Action

They all define what "doing the right thing" means.

🔓

Free Choice

They assume people can make rational decisions of their own free will.

🌍

Human Well-Being

The ultimate goal is to contribute positively to humanity.

📌

Obligations vs Preferences

They separate moral duties from mere personal preferences.

🌐

Ethical Relativism

Theory 1

Core claim: There are no universal moral rules. Right and wrong vary by individual or culture — and both can be "correct" simultaneously.

Think of it as: "What's right is whatever you (or your culture) think is right."

It comes in two flavours:

Subjective Relativism

  • Each individual decides right/wrong for themselves.
  • Your approval of X makes X right — for you.
  • Two people can disagree and both be "right."
✗ Not a workable theory

Cultural Relativism

  • Each culture decides right/wrong collectively.
  • What's moral in one country may be immoral in another.
  • Moral guidelines vary by place and time.
✗ Not a workable theory

Advantages of Cultural Relativism

  • Promotes cooperation and mutual respect
  • Enables equality across cultures
  • Preserves human cultural diversity
  • Lets communities build their own moral codes

Disadvantages of Cultural Relativism

  • Fuelled by personal bias
  • Could create social chaos
  • Based on perfection of humanity (unrealistic)
  • Can actually reduce real diversity
Why SR fails: Blurs doing what's right vs doing what you want. Makes moral disagreement impossible. Based on non-reasoning.
Why CR fails: No universal guidelines. Gives tradition more weight than reason or facts. Weak tool for ethical persuasion.
✝️

Divine Command Theory

Theory 2

Core claim: Morality comes from God's commands. What God commands = moral. What God forbids = immoral. Holy books are the guides.

Think of it as: "God's will is the ultimate rulebook."

Advantages

  • God is all-good and all-knowing → perfectly reliable
  • Universal rules that apply to everyone, everywhere, always
  • Commands are completely objective (not opinion-based)
  • Religious texts provide a clear practical guide
  • Obedience is motivated by reward/punishment

Challenges (common critiques)

  • Requires prior acceptance of faith
  • Disagreements between religions on what God commands
  • Euthyphro dilemma: Is it good because God commands it, or does God command it because it's good?
📜

Deontology (Duty-based)

Theory 3

Core claim: Morality is about following duties and rules — not about the outcome. An action is moral if it follows the right rule, regardless of consequences.

Key thinker: Immanuel Kant — "Act only according to rules you'd want universalised."

Memory hook: 🔒 "Duty first, results second." A doctor must tell the truth even if it upsets the patient, because honesty is a duty.

📊

Consequentialism / Utilitarianism

Theory 4

Core claim: The morality of an action is determined entirely by its consequences. The right action produces the greatest good for the greatest number.

Key thinker: John Stuart Mill, Jeremy Bentham.

Memory hook: 📈 "The ends justify the means." Calculate outcomes, pick what maximises happiness for the most people.

🤝

Social Contract Theory

Theory 5

Core claim: Morality arises from agreements people make with each other to live together in society. Rules are valid because we all implicitly or explicitly agree to them.

Key thinkers: Hobbes, Locke, Rousseau.

Memory hook: 📝 "Society is one big contract — we all signed it by living here."

🌟

Virtue Ethics (Character-based)

Theory 6

Core claim: Morality is about who you are, not just what you do. Focus on building virtuous character traits — honesty, courage, compassion — and right actions will follow.

Key thinker: Aristotle.

Memory hook:"Be a good person and good actions come naturally." Instead of rules, ask: "What would a virtuous person do here?"

Tricky Distinctions — Deep Dives

Exam Focus
Morality vs Ethics — aren't they the same word? 🤔

Morality is the system itself — the rules, principles, and values a society actually uses to guide behaviour.

Ethics is the academic, philosophical study of that system — questioning whether those rules are justified, rational, and fair.

Analogy: Morality is the game. Ethics is the sports commentator analysing whether the rules of the game make sense.

Subjective Relativism vs Cultural Relativism — what's the key difference? 🌐

Both say there are no universal moral rules. The difference is who decides:

Subjective Relativism: Each individual is the moral authority for themselves. "I approve of X, so X is right — for me."

Cultural Relativism: Each culture or society collectively decides what's moral. "Our culture approves of X, so X is right here."

The critical similarity: both are considered non-workable because they lack universal standards and make ethical debate impossible.

Micro-level vs Macro-level rules — what do they mean? 📏

Micro-level (directives): Rules that guide individual behaviour. Example: "Do not steal." "Do not harm others." These are personal conduct guidelines.

Macro-level (social policies): Rules that guide society as a whole. Example: "Software should be protected." "Privacy should be respected." These become laws, policies, and institutional standards.

Think of it as: micro = personal rules, macro = societal rules.

Why do we even study ethics philosophically? 🎓

The lecture gives five reasons:

1. Critical evaluation — to analyse arguments rigorously rather than accepting them at face value.

2. Support a position — to provide justified reasoning behind a claim or view.

3. Convince others — to persuade people to adopt or reject a position using logical reasoning.

4. Consistency — to ensure our beliefs are logically coherent and don't contradict each other.

5. Meaningful dialogue — to engage in genuine, productive moral conversations.

What are Morality's three justification grounds? ⛪📚⚖️

Moral rules and principles are justified (grounded) in one of three systems:

Religion: Commands from God or sacred texts define what is morally right.

Law: What is legally permitted/prohibited reflects moral expectations of society.

Philosophy (Ethics): Rational reasoning and ethical theories justify moral rules independently of religion or law.

These three are the foundations — everything else builds on top of them.
