Kantian Deontology - Main Body

Immanuel Kant (1724-1804) Metaphysics of Morals

  • To act morally is to do ones duty > ones duty is to obey moral law.
  • We should not act out of love or compassion.
  • Aught implies can. I aught to > I can > I must

Summum bonum

  • We must have immortal souls because the ultimate end can't be achieved in one lifetime.
  • God must exist to provide the opportunity for S.B.
  • Kant: "The starry heavens above me and the moral law within me."

Moral knowledge is a priori synthetic. Knowledge is gained before experience but may need testing.

Humans have the freedom to rationalise - animals don't.

  • Humanitarian - men are treated equally. - NHS.

Kantian Deontology - Arguments Against

JS Mill: When there are conflicting duties, no guidance is given.

Bentham: The unchanging principles are really a matter of subjective opinion. Where does objective morality come from?

William K Frankena: "There is more to moral POV than being willing to universalise ones rules."

  • Are we content to know we should do our duty without understanding why?
  • How far can a good will mitigate a disastrous outcome?
  • Kant makes no allowance for compassion or sympathy as motivation (La Follette)
  • Jesus criticised the Pharisees for going by the exact letter of the law.

Against WD Ross > How can you rank Prima Facie duties? Ross thought you could solve this by relying on intuition.
