of the good will.
This sounds like a pretty mysterious claim.
But perhaps we can find out more by looking at what Kant
understands as a duty.
A first observation:
We only have a conception of duty (and of law) because we have a will.
Other animals don’t have a will (they do not choose what they do, they
just do it), and, therefore, they could never act out of duty.
Duty for Kant is one of the things that can move us to action (we
sometimes do what we do because we have to and not necessarily
because we desire to)
The other thing that can move us is self-interest. Self-interest and
duty are two completely separate things for Kant. But it is not easy to
separate them when it comes to
actions. Why? Because they only affect one’s motives and motives are
hard to figure out.
Example of helping a friend.
Some do it because they love their friends, because they feel sympathy
