ABSTRACT
Immanuel Kant believed in an objective right and wrong based on reason. We should do the right thing just because it is right and not because it fulfils our desires or is based on our feelings. We know what is right not by relying on our intuitions or facts about the world, but by using our reason. To test a moral maxim, we need to ask whether we can always say that everyone should follow it and we must reject it if we cannot.
