Thinkers to Study

Western Tradition

  • Aristotle — Virtue Ethics: character formed through habit; courage, justice and temperance as cardinal virtues
  • Immanuel Kant — Deontological Ethics: judge actions by the principle (maxim), not consequences; categorical imperative
  • Jeremy Bentham & J.S. Mill — Utilitarianism: maximise aggregate welfare
  • John Rawls — Theory of Justice: fairness to the least advantaged; veil of ignorance

Indian Tradition

  • Mahatma Gandhi — Trusteeship, non-violence, means-ends integrity
  • Swami Vivekananda — Service as worship; practical Vedanta
  • Kautilya — Arthashastra ethics in governance: the ruler's dharma
  • Bhagavad Gita — Nishkama Karma: action without attachment to fruits

Gandhi, Vivekananda and Kalam are the highest-frequency thinkers, but from 2020 onwards UPSC has tested progressively newer thinkers.

Critical note on Kant: The most common mistake is citing Kant to justify outcome-based reasoning — Kant evaluates the principle (maxim) of the action, never its consequences.

Case Study Strategy: SAFE Framework

  1. S — Stakeholders: identify all affected parties (citizen, state, officer, community)
  2. A — Alternatives: list at least 3 courses of action
  3. F — Filter: apply ethical principles (integrity, empathy, constitutional values) to select the best option
  4. E — Execute & Evaluate: explain the chosen action and its probable consequences
  • Never choose a purely self-serving option — evaluators reward the answer that balances duty, empathy and constitutional values.
  • Cite the relevant thinker briefly — one line is enough.
