We should do the right thing
simply because it is right
We must reject
any theory we
cannot universalise
(apply to everyone)
Consequences do
not matter. At all.
Comes from his book 'Critique of practical reason.'
Kant and reason
Kant believed the world we
experience around us is 'phenomenal'
- not the world as it really is
If our senses were different, we
would experience the world differently
What is important is the noumenal world, which is the
world as it really is. We experience this through reason.
Kant's moral theory
Desires and feelings are not
anything to do with morality
(that is Hume's theory)
Morality comes from autonomy, good will, and duty.
Autonomy
Freedom to choose; no action can be moral
for Kant unless it is freely chosen.
The opposite is heteronomy - something is right because it
satisfies an emotion, goal or desire.
Good will
Kant believed only good will
was intrinsically good
The intention for our action must be good
Duty
Duty must be
done for its own
sake
You should not help someone because it
makes you feel good to have helped
someone, for instance
Categorical imperative
A hypothetical imperative is something you
should do to achieve a goal; for example, if I
want to pass my AS levels, I should revise.
A categorical imperative is something you
simply MUST do. They apply to everyone.
How do you tell if something is a categorical imperative?
Three maxims
Universalising rules
Something cannot be a moral law unless you'd
be happy for everyone else to do the same -
otherwise this is a contradiction because not
everyone would follow the same moral law
Eg. If you universalise,
'break promises when it
suits you,' promises will
have no meaning and the
entire rule is pointless.
Never treat
people as a
means to an end
People must be the end, never the means. If not, we deny
them the right to be rational and to make their own judgements.
Act as if in the Kingdom of Ends
Act as if everyone is a free, autonomous moral agent
Postulates
We must postulate
(suggest or assume
the existence of)
three things for Kant's
theory to work.
God
In the next world, there will be no conflict between
duty and happiness; God ensures goodness is
rewarded. See moral argument mindmap.
