“Kant argues that to act in the morally right way, people must act from duty (deon). Second, Kant argued that it was not the consequences of actions that make them right or wrong but the motives of the person who carries out the action.
Kant’s argument that to act in the morally right way one must act purely from duty begins with an argument that the highest good must be both good in itself and good without qualification. Something is “good in itself” when it is intrinsically good, and “good without qualification”, when the addition of that thing never makes a situation ethically worse. Kant then argues that those things that are usually thought to be good, such as intelligence, perseverance and pleasure, fail to be either intrinsically good or good without qualification. Pleasure, for example, appears not to be good without qualification, because when people take pleasure in watching someone suffering, this seems to make the situation ethically worse. He concludes that there is only one thing that is truly good:
Nothing in the world—indeed nothing even beyond the world—can possibly be conceived which could be called good without qualification except a good will.”
