Because human beings are the end of development, all other imperatives and concerns are of instrumental significance, i.e., all such imperatives and concerns must be seen and utilised as means toward enhancing human capabilities and furthering human development. The reduction of capability poverty constitutes the central agenda of the human development frame.
Human beings have potentially infinite capabilities.
But certain human capabilities are more fundamental than others. The capabilities required to lead a healthy and knowledgeable life and to acquire a decent level of living are certainly fundamental. Because human beings are essentially creative beings, the capabilities required to work productively is fundamental as well.
