Kantian Ethics




Some key ideas from the lecture:

  • Kantian ethics responds to the need for moral truths to have an independent justification which depends on reason and not just on intuition or implicit agreement.
  • Kant argues that if a law is to be morally valid, then it must follow with absolute necessity.
  • He provides such an algorithm in the form of the Categorical Imperative.
  • The Categorical Imperative is similar to–but more universal and less personal than–the Golden Rule.
  • The core of morality is not what we do but why we do it.
  • Principle-based ethical theories are called deontological.

If you have any questions, feel free to raise them in the comments section. On Wednesday I’d like to hear your ideas about whether you foresee any problems with applying this ethical theory to specific moral problems.
