We already believe that the more objective a value is, the more real it is. This is shown by the way we distinguish real values from apparent ones. Only detachment from all particular desires for objects and persons can be completely objective. Therefore, only detachment from all particular objects and persons has real value. We determine what things are most valuable by seeing what values last the longest or are valued from the most points of view.
All subjective values are like itches and hunger.
The pleasure we get from scratching an itch or from eating arises from a defect or deficiency in us. Once we fill the defect we will feel good, but the defect will inevitably arise again and give rise to dissatisfaction. We would rather never itch or never be hungry, than always be scratching and eating. Therefore, all subjective values are defective in this way. We ought to eliminate all desires rather than trying to satisfy them.
