"Shaka was able to invest his talents and creative energies in a worthwhile endeavor of construction. He was not concerned with fighting for or against slave traders; he was not concerned with the problem of how to resell goods made in Sweden and France. He was concerned with how to develop the Zulu area within the limits imposed by his people’s resources. It must be recognized that things such as military techniques were responses to real needs, that the work of the individual originates in and is backed by the action of society as a whole, and that whatever was achieved by any one leader must have been bounded by historical circumstances and the level of development, which determine the extent to which an individual can first discover, then augment, and then display his potential."
