Kant Biography


II. Kantian Duty

Kant's Categorical Imperative

Act only according to that maxim by which you can at the same time will that it should become a universal law

  • An ethical theory should be rooted in consistency and fairness, making it universal
  • Deon - Gr. duty/obligations
  • Immanuel Kant, 18th century
  • Moral rules should always be followed because of reason


III. Categorical Imperative

Kant's Categorical Imperative

  • Imperative
    • Something you ought to do
  • Hypothetical "oughts"
    • You ought to do this, to get that.
    • Hypothetical because you may not want that, in which case you don’t have to do this.
    • Goal oriented conduct
  • Categorical "oughts"
    • You ought to do this. Period.
    • Morality - an absolute rule, regardless of desire
  • Justifying Categorical “oughts"
    • Categorical oughts are justified by reason, not desire
    • Every rational person must accept the Categorical Imperative
    • Consider the maxim (universal rule) that should be followed
    • The person who follows the Categorical Imperative is the Autonomous Lawmaker, the ideal citizen


IV. Advantages of Deontology

Kantian Deontology

  • Most lay people enact a form of deontology naturally
  • Following maxims is both moral and rational
  • Personal equality - one person isn’t special from a moral point of view
  • Reliance on reason


V. Criticisms of Deontology

The Invention of Lying

  • Determining moral laws in a way that will not generate exception
  • Conflicting moral laws
    • The Case of the Inquiring Murderer
      • From “On a Supposed Right to Lie from Altruistic Motives” - Kant
    • You have 3 options.
      • You tell the truth. (“My friend has gone home.”)
      • You say nothing, in which case, the murder will still go to the friend’s house.
      • You lie. (“My friend went in the opposite direction.”)
    • Strategy
      • I lie
        • My friend escapes +
          • But I committed a moral wrong –
        • My friend is killed –
          • And I committed a moral wrong –
      • I tell the truth
        • My friend escapes +
          • And I committed no wrong +
        • My friend is killed –
          • And I committed no wrong because the wrongdoing was committed by the murderer, not me +
      • Consequences are uncertain
      • Better to stick with a known good (that may have a negative effect) than take a chance on a possible good (requiring a negative cause)
  • Pessimistic view of foreseeing consequences
  • Presumes doing duty absolves us of consequences that result from our action or inaction
  • Maxims can be taken to extremes
  • Common sense lies (little white lies)
