Kant’s argument that to act in the morally right way, one must act 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 to not 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.
