  The most influential argument that appeals to the nature of the human good holds that for an activity or relationship to improve a person’s life he or she must endorse its value. This argument, which is often referred to as the endorsement constraint, holds that political measures that compel or guide people into activities or pursuits that they do not value will be counterproductive. These measures will not improve the lives of anyone; and they may do harm by directing people away from activities and pursuits that would add value to their lives.
