Morality vs Ethics — What's the Difference?
Foundations
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.
What Morality Consists Of
BreakdownMicro-level (directives): Individual rules — "Do not steal", "Do not harm others."
Macro-level (social policies): Societal rules — "Software should be protected", "Privacy should be respected."
Four Features of a Moral System
Must KnowPublic · 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.
The 4 Core Ethical Principles
PrinciplesBeneficence · 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.
What All Ethical Theories Have in Common
Shared CoreRight 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.
The 6 Ethical Theories
Core ContentRelativism (Ethical Relativism) · Divine Command Theory · Deontology (Duty-based) · Consequentialism (Utilitarian) · Contract-based (Social Contract) · Virtue Ethics (Character-based)
Ethical Relativism
Theory 1Core 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."
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.
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 CR fails: No universal guidelines. Gives tradition more weight than reason or facts. Weak tool for ethical persuasion.
Divine Command Theory
Theory 2Core 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 3Core 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 4Core 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 5Core 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 6Core 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 FocusMorality 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.
