6.1 Ethics in General: Concepts, Sources & Theories

Key Takeaways

  • Ethics is the systematic study of right and wrong conduct and of good character. Law sets the minimum society enforces, while ethics often demands more than the law requires.

  • Normative ethics has three classic families: consequentialism (judge acts by outcomes, as in utilitarianism), deontology (judge acts by duties and rules, as in Kant), and virtue ethics (judge by character, as in Aristotle).

  • Kant's categorical imperative asks whether the rule behind an act could be made a universal law, and requires treating people never merely as a means.

  • Ethical relativism holds that right and wrong vary by culture. Universalism or absolutism holds that some moral standards apply everywhere, which is the position of Islamic ethics.

  • In finance, ethics matters because of information asymmetry, conflicts of interest, and the trust customers place in institutions that hold their money.

Ethics in General: Concepts, Sources & Theories

Quick Answer: Ethics is the study of what is right and wrong and of what makes a good person. Secular moral philosophy offers three classic ways to judge an action: by its consequences (utilitarianism), by duties and rules (Kant's deontology), or by the character it expresses (Aristotle's virtue ethics). Islamic ethics, covered in section 6.2, shares much with these theories but grounds morality in revelation and accountability to Allah.

AQIF Module 3 begins with "Ethics in General" before moving to akhlaq and Islamic finance. Exam questions here test definitions and the ability to recognise which theory a statement reflects.


1. Key Definitions

TermMeaning
EthicsFrom the Greek ethos (character, custom): the systematic study of right and wrong conduct, good and bad character, and the reasons behind moral judgments
Morality / moralsFrom the Latin mos (plural mores, custom): the standards of conduct that a person or community actually holds
ValuesThings a person or organisation regards as important, such as honesty, fairness or security
LawRules made and enforced by the state, with penalties for breach
Business ethicsThe application of ethical principles to commercial decisions and organisations
Professional ethicsThe duties that members of a profession owe to clients, the public and the profession, usually written into a code

Law versus ethics. Law and ethics overlap but are not the same. Some acts are legal but unethical, such as pushing an unsuitable product on a confused elderly customer in a way that technically meets disclosure rules. Some acts are ethical but not legally required, such as voluntarily restructuring a debt for a borrower hit by disaster. Law is usually described as the minimum standard society will enforce. Ethics asks what a good person or institution should do.


2. Branches of Ethics

  1. Meta-ethics: the nature of morality itself. What does "good" mean? Are moral facts objective?
  2. Normative ethics: theories of how we ought to act, such as utilitarianism, deontology and virtue ethics.
  3. Applied ethics: applying those theories to specific fields, such as business, medical or environmental ethics.
  4. Descriptive ethics: describing what people actually believe and do, without judging it.

3. Sources of Ethical Standards

People draw their sense of right and wrong from several sources, often at once:

  • Religion: revealed guidance and religious teaching.
  • Philosophy and reason: reasoned theories of right action.
  • Culture and society: customs, traditions and social expectations.
  • Law and regulation: rules that also signal what society regards as wrong.
  • Professional codes: for example banking or accounting codes of conduct.
  • Family, upbringing and personal conscience.

4. The Main Normative Theories

4.1 Consequentialism (Teleological Ethics)

An action is right if it produces the best consequences (telos, end or goal).

  • Ethical egoism: the right act is the one that best serves the agent's own long-term interest.
  • Utilitarianism: the right act produces the greatest good for the greatest number. Jeremy Bentham measured good as pleasure and the absence of pain. John Stuart Mill distinguished higher (intellectual, moral) from lower pleasures.
    • Act utilitarianism judges each act by its outcomes.
    • Rule utilitarianism follows the rules that generally produce the best outcomes.
  • Criticism: it can justify harming a minority if the majority gains, and outcomes are hard to predict and measure.

4.2 Deontology (Duty-Based Ethics)

An action is right if it conforms to a moral duty or rule, whatever the consequences (deon, duty).

  • Immanuel Kant's categorical imperative:
    1. Universalisability: act only on a rule (maxim) you could will to become a universal law. Lying to win a sale fails, because if everyone lied, trust and the practice of selling would collapse.
    2. Humanity as an end: treat people never merely as a means, always also as ends in themselves.
  • Criticism: duties can conflict, and rigid rules may ignore disastrous outcomes.

4.3 Virtue Ethics

Ethics is about being a person of good character, not only about isolated acts.

  • Aristotle: virtues are the golden mean between two vices, as courage lies between cowardice and recklessness. Practical wisdom (phronesis) lets a person act well, and the goal is human flourishing (eudaimonia).
  • In business: honesty, fairness, prudence and integrity become part of the professional's character and the organisation's culture.
  • Criticism: it gives less precise guidance for specific dilemmas.

4.4 Rights and Justice Theories

  • Rights-based ethics: people have rights, such as life, property, privacy or fair treatment, that others must respect even when overriding them would produce more total benefit.
  • Justice as fairness: John Rawls (A Theory of Justice, 1971) asked which principles people would choose behind a "veil of ignorance", not knowing their own position in society. He argued they would protect basic liberties and allow inequalities only if they benefit the least advantaged.

4.5 Relativism vs. Universalism

  • Ethical relativism: right and wrong depend on the culture or the individual, so no standard applies to everyone.
  • Ethical universalism (absolutism): some moral standards, such as prohibitions on fraud or murder, hold everywhere. Islamic ethics is universalist about its core standards while allowing legitimate custom ('urf) in details.
TheoryQuestion it asksTypical banking illustration
UtilitarianismWhich option produces the most good overall?Approving a restructuring that saves a business and jobs at modest cost to the bank
Kantian deontologyCould this rule be universal, and am I using someone merely as a means?Refusing to mis-sell even when targets would be met
Virtue ethicsWhat would an honest, prudent banker do?Building a culture of integrity, not just rule-following
Rawlsian justiceIs the outcome fair to the least advantaged?Fair treatment and protection of vulnerable customers

5. Ethics in Organisations and Finance

Ethical issues arise at several levels:

  • Individual: honesty, conflicts of interest, and misuse of information.
  • Organisational: culture, incentives and remuneration, and governance.
  • Industry: market-wide practices such as mis-selling or rate manipulation.
  • Societal: the effects of finance on financial stability, inequality and the environment.

Carroll's pyramid of corporate social responsibility (1991) is a common framework. It lists, from the base up, a company's economic, legal, ethical and philanthropic responsibilities.

Finance is especially exposed to ethical failure because of:

  • information asymmetry: the bank knows more than the customer;
  • agency problems: managers and staff act for others, such as depositors, investors and shareholders;
  • incentives: sales targets and bonuses can reward short-term behaviour;
  • trust: customers hand over their money and their data.

A simple personal test helps in practice: Would I be comfortable if this decision were reported in tomorrow's newspaper, or explained to my family?


6. Secular Ethics and Islamic Ethics Compared

DimensionSecular ethical theoriesIslamic ethics (akhlaq)
Ultimate sourceHuman reason, experience and social agreementRevelation (Quran and Sunnah), with reason ('aql) and custom ('urf) in a supporting role
StandardVaries by theory; sometimes relativeCore standards fixed by Shariah; details adapt to circumstances
AccountabilityConscience, society and law in this worldThis world and the Hereafter
MotivationUtility, duty, flourishing, or fairnessSeeking Allah's pleasure: taqwa, ihsan
OverlapHonesty, fairness, keeping promises, avoiding harmThe same virtues, reinforced as religious duties

Islamic ethics borrows insights from all the theories: concern for outcomes appears in maslahah, firm duties in the rulings of Shariah, and virtue in the cultivation of akhlaq. What differs is the source of authority and the accountability. Section 6.2 develops this in detail.
