Kantian deontological ethics’ main claim
To act morally is to act out of duties which are discoverable by reason alone
Kant’s account of what is meant by a ‘good will’
Wanting to do the right thing is the most valuable thing of all.
It is the only thing that is good ‘without qualification’
It is good regardless of the consequences of any actions that might result
Acting with a good will ultimately means wanting to do something because it’s your duty.
Acting in accordance with duty
doing the right thing for some other reason
Acting out of duty
doing the right thing because it’s the right thing
Hypothetical imperative
commands that only apply to you if you want something
categorical imperative
Commands that apply regardless of what you want and so apply to everyone
What is the first formulation of the categorical imperative
Act only in accordance with that maxim through which you can at the same time will that it become a universal law”
(You should only act on intentions that everyone could act on without any contradictions)
What duty do we have if there is a contradiction?
A duty to not act on that maxim
Maxim
A maxim is the intention behind an action, made into a rule. It normally has the form of an action that is going to be done and the ‘end’ or purpose of that action
Contradiction in conception
it’s impossible to think of you doing the action and everyone else also doing the action (leads to a perfect duty not to do that action)
Contradiction in will
You can’t really want you and everyone else to do the action (leads to imperfect duty not to do that action)
What is the second formulation of the categorical imperative?
So act that you use humanity, whether in your own person or in the person of any other, always at
the same time as an end, never merely as a means
(You should never just use a person to get something else - you should always treat people with dignity and respect because they’re rational)
