Normative ethics: virtue, duty and consequences

Philosophy (BA) · Ethics · free study notes for exams, placements and interviews

In short

Normative ethics asks what makes an action right, as opposed to meta-ethics (what "right" means) and applied ethics (particular problems). It has three dominant families: virtue ethics (what kind of person should I be?), deontology (what duty binds me, regardless of outcome?) and consequentialism (which act produces the best results?). Indian BA Philosophy papers under UGC CBCS devote whole units to Aristotle's doctrine of the mean, Kant's categorical imperative and Bentham-Mill utilitarianism, and ask candidates to compare them on a case. The same three frameworks reappear in UPSC Civil Services GS Paper IV (Ethics, Integrity and Aptitude), UGC-NET Philosophy, CLAT/judiciary ethics questions, and in corporate interviews for compliance, governance, HR and AI-policy roles, where a candidate is handed a dilemma and asked to reason it out.

Formulas and examples

Hedonic calculus (Bentham): net utility U = Σ over all affected persons of (pleasure − pain), each unit weighted by intensity × duration, discounted for certainty (probability) and propinquity, and extended by fecundity, purity and extent.
Expected utility of an option: EU = Σ pᵢ × Uᵢ, where pᵢ is the probability of outcome i and Uᵢ its utility in arbitrary utility units (utils). Utils are ordinal-to-interval constructs, not SI units; rupee values are often used as a proxy in policy work.
Act-utilitarian rule: choose act A* such that EU(A*) = max over all available acts.
Rule-utilitarian rule: choose the act required by rule R*, where R* maximises expected utility if generally followed.
Kant's universal-law test (no arithmetic): state the maxim → universalise it → ask whether the universalised world is (a) self-contradictory (perfect duty violated) or (b) impossible to will (imperfect duty violated).
Aristotle's mean: virtue V lies between vice of excess and vice of deficiency, with the mean located by phronesis relative to the agent - explicitly *not* the arithmetic midpoint.

Example 1 - Hedonic calculus with real numbers (a factory relocation). A firm can shift a unit from Pune to a backward district. Affected groups, with utility in utils (positive = pleasure):

GroupPersonsUtility per personProbabilityWeighted total
New-district workers gaining jobs500+400.9500 × 40 × 0.9 = +18,000
Pune workers losing jobs120−901.0120 × (−90) × 1.0 = −10,800
Shareholders2,000+30.82,000 × 3 × 0.8 = +4,800
Pune local traders60−250.760 × (−25) × 0.7 = −1,050

Net utility = 18,000 − 10,800 + 4,800 − 1,050 = +10,950 utils → act utilitarianism approves the shift. But the 120 workers bear the entire loss. A rule utilitarian asks what rule maximises utility generally: "relocate only with retraining and severance" - if severance costing 3,000 utils of shareholder gain lifts the losers from −90 to −30, net = 18,000 − 3,600 + 1,800 − 1,050 = +15,150 utils, higher still. A Kantian asks whether the 120 are being used merely as means - consultation, notice and compensation respect them as ends. A virtue ethicist asks whether the decision shows justice and liberality or meanness.

Example 2 - Act versus rule utilitarianism (the false alibi). A manager can give a false statement to an auditor to save a colleague from dismissal.

Example 3 - Kant's universal-law test applied step by step (the lying promise).

  1. Maxim: "When short of money, I will borrow on a promise to repay that I know I cannot keep."
  2. Universalise: everyone in need borrows on insincere promises.
  3. Result: no lender believes a promise; the institution of promising collapses.
  4. Hence the maxim is self-contradictory in conception - the act could not even be performed in that world.
  5. Verdict: a perfect duty is violated; the act is forbidden regardless of the good the money would do. Compare by Formula II: the lender's reason is bypassed, so the lender is treated merely as a means.

Example 4 - Aristotle's mean, quantified to show it is not an average. A corporate social-responsibility budget: the firm's annual profit is ₹10 crore. Prodigality would be giving ₹9 crore (the firm fails); meanness would be ₹0. The arithmetic midpoint is ₹4.5 crore, but the mean "relative to the agent" fixed by practical wisdom - and in Indian law by Companies Act, 2013 section 135, which requires qualifying companies to spend at least 2% of average net profits of the preceding three financial years - lands near ₹20 lakh. The point: the ethical mean is set by reason and circumstance, not by halving the extremes.
