1. Modern life and applied ethics
Ethics in human life · New approaches to modern issues · Living ethically
- Ethics: How to Decide What Is Right – Ethics (moral philosophy) asks what we ought to do and why. Values such as honesty, kindness, fairness and respect guide choices. Three main theories help: consequences (utilitarianism, Bentham and Mill: most good for most people), duty (Kant: act on rules you could want everyone to follow; treat people as ends, never only as means) and virtue (Aristotle: build good character; virtue is the mean between extremes). Conscience is our inner sense of right and wrong. Freedom brings responsibility. Meta-ethics asks what "good" means and whether values are universal or relative. Applied ethics deals with the environment, animals, work, friendship and peace.
- Applied Ethics: Using Moral Ideas on Real-Life Problems – Applied ethics takes big moral ideas and uses them on real cases: honesty and friendship in personal life, privacy and AI in technology, gene editing in medicine, how we treat animals and nature, and fairness in property and work. Three lenses help: consequences (what results?), duty (what rules and rights?), and character (what would a good person do?). A clear method turns opinions into a reasoned judgement: get the facts, list stakeholders, find options, test them against principles, then decide and explain.
- Moral Reasoning: Thinking Clearly About Right and Wrong – Moral reasoning is careful thinking about what we ought to do. It starts by separating facts (what is, which can be checked) from values (what ought to be). To judge an action, look at four parts: the intention, the means, the circumstances and the consequences. A sound moral judgement joins a principle (such as "do not cause needless harm") with true facts about the case. Virtues like honesty, fairness, care and courage help us act on good judgements. People still act wrongly because of peer pressure, self-interest, ignorance, weak will and excuses. Moral imagination, stepping into the shoes of everyone affected and looking for new options, makes decisions wiser. A simple inquiry method (problem, facts, options, tests, decide, review) helps solve real dilemmas, and good reasons are why being moral matters: it builds trust, protects others and shapes who we become.
2. Life and ethics
Life and death · Dignity of life · Love and sexuality
- Bioethics: Deciding What Is Right in Biology and Medicine – Bioethics asks whether we should do what biology and medicine now let us do. It uses four principles: autonomy (respect choice), beneficence (do good), non-maleficence (do no harm) and justice (fairness). Human dignity means a person is never only a means to an end, so informed consent is needed. Therapeutic cloning may be allowed under strict rules; reproductive human cloning is banned in most countries. Start-of-life and end-of-life questions are weighed as benefits against risks and values.
- Respect, Consent and Gender Equality: Sexual Ethics for Teens – Sexual ethics means treating your own body and other people with respect. Consent must be clear, free, informed and can change at any time. Pressure, fear or power make a "yes" invalid. Everyone has equal rights whatever their gender, and anyone can ask a trusted adult for help.
3. Society and ethics
Work and happiness · Fair distribution · State authority and civil disobedience
- Career Ethics and Work Ethics – Work ethics are the values that guide how we do our jobs: honesty, responsibility, fairness, respect and safety. Work gives money, growth and a way to help others. Every profession adds special duties, such as a doctor keeping secrets or an engineer putting safety first. When a hard choice appears, a simple ladder helps: stop, find facts, see who is affected, list options, choose, and test.
- Social Justice: Fair Shares for All – Justice means giving each person their due. Social justice is about fair sharing of goods, services and chances in society. Three principles guide fair sharing: equal treatment for equals, reward in proportion to effort and skill, and extra help for special needs. They must be balanced. John Rawls suggested choosing society's rules from behind a 'veil of ignorance', not knowing what position we would get; a rational person would then protect the worst-off. Pursuing social justice means first securing basic needs (food, water, housing, health, education, minimum wage) for everyone. People disagree on how: free-market supporters want open competition with a small state; others want the state to provide welfare. India uses a mix.
- Civic Ethics: Common Good, Citizens and the State – Civic ethics asks how we should act as members of a community. My own good and the common good can clash, as with a shared well. Fair sharing keeps the resource alive for everyone. Citizens owe duties to neighbours and to a fair state; officials must be honest; and people may peacefully refuse an unjust law, which is called civil disobedience.
4. Science and ethics
Ethics of research · Information technology and media · Views of nature
- Ethics in Science and Technology – Science and technology give great power, so we also ask "should we?" and not only "can we?". Science ethics means weighing benefit against risk, keeping people, animals and nature safe, being honest with data, taking responsibility for how results are used, and letting citizens share in big decisions about science.
- Digital Footprints and Netiquette – A digital footprint is the trail of data we leave online. Active footprints are shared on purpose (posts, comments, forms); passive footprints are collected without us noticing (cookies, browsing history, location, IP address). Footprints are hard to erase and can be seen by others later. We live in a digital society where learning, banking, shopping and government services are online; a responsible user of it is a digital citizen (netizen). Net etiquette means being ethical (respect copyright, share reliable information), respectful (privacy, diversity, no bullying) and responsible (avoid oversharing, don't feed trolls). Communication etiquette asks us to be precise, polite and credible; social media etiquette asks us to choose passwords and privacy settings wisely, think before uploading, and verify before sharing.
- Environmental Ethics: Who Deserves Our Care? – Environmental ethics asks what we owe to nature, animals and future people. Picture a circle of moral concern. Anthropocentrism keeps only humans inside; nature has instrumental value (useful to us). Sentientism (Singer, Bentham) adds animals that feel pain: animal welfare says reduce suffering, animal rights (Regan) says animals must not be used as mere tools. Biocentrism (Schweitzer, Taylor) gives every living thing value. Ecocentrism (Leopold's land ethic, deep ecology) values whole ecosystems. Many Eastern and Indigenous traditions see humans as part of nature. Intergenerational justice and sustainability add future people. Real cases (dams, forests, animal testing, climate) often bring these views into conflict.
5. Culture and ethics
Art and morality · Consumption ethics · Cultural diversity
- Philosophy of Art: What Is Art, and Why Does It Matter? – The philosophy of art (part of aesthetics) asks: what is art, what is beauty, is taste only personal, what makes a creator, and can art show truth? Answers have changed from "art copies nature" to "art expresses feeling" to "the idea is the art".
- Ethical Consumption – Ethical consumption means choosing what to buy while thinking about the people who made it and the nature it uses. Fair trade pays workers a fair share, and buying less, second-hand or repaired things cuts the footprint. Many small choices change what shops sell.
- Cultural Diversity – Cultural diversity means many groups with different ways of life live together. Ethnocentrism judges others by your own culture; cultural relativism first understands a custom in its own setting. Prejudice and stereotypes block respect. Societies have a mainstream culture, subcultures and countercultures. Universal human rights set the limit: differences deserve respect, harm to people does not.
6. Peace and coexistence
Social conflict · Unification issues · International justice
- Peace Education: How People Build Lasting Peace – Peace is more than 'no war'. Negative peace means no fighting. Positive peace means fairness, trust and a good life for all. Violence can be direct (hitting, war), structural (unfair rules that keep people poor) or cultural (ideas that make harm look normal). Thinkers gave us tools: Mozi taught equal care for all and opposed attacking wars; Kant said fair governments, a league of free states and kindness to visitors can make peace last; Gandhi showed non-violent resistance. Conflicts are solved step by step: cool down, listen, find needs, think of options, agree. After division or war, reconciliation is built like a bridge: talks, truth, apology, trade, family meetings and shared projects. Germany (1990) and South Africa's truth commission are examples; divided peoples such as on the Korean peninsula still discuss how peaceful unification could happen.
- Global Justice: Fair Trade, Aid and Reducing Inequality – Global justice asks what is fair between countries and between people across the world. Incomes are very unequal. Fair trade gives producers a fair price, and development aid (ODA) helps poorer countries build schools, health and jobs. Real justice also needs peace, honest rules and a say for poorer countries.
