As the notion of conversion factors show, the capability approach explicitly endorses and relies upon a key analytical distinction in practical philosophy, namely the means-ends distinction. The approach stresses that we should always be clear, when valuing something, whether we value it as an end in itself, or as a means to a valuable end. For the capability approach, the ultimate ends of interpersonal comparisons are people’s capabilities. This implies that the capability approach evaluates policies and other changes according to their impact on people’s capabilities as well as their actual functionings. It asks whether people are able to be healthy, and whether the means or resources necessary for this capability, such as clean water, adequate sanitation, access to doctors, protection from infections and diseases, and basic knowledge on health issues, are present. It asks whether people are well-nourished, and whether the means or conditions for the realization of this capability, such as having sufficient food supplies and food entitlements, are being met. It asks whether people have access to a high-quality education system, to real political participation, and to community activities that support them, that enable them to cope with struggles in daily life, and that foster caring and warm friendships.
