Tim Hayward and Yukinori Iwaki, "Had We but World Enough, and Time: Integrating Ecological and Temporal Perspectives on Global Justice"
The requirements for a decent life come in the overarching dimensions of time and (ecological) space. The latter has attracted attention from some global justice theorists, while the former is a comparably neglected matter. This paper aims to integrate temporal and ecological perspectives in order to provide an enriched conceptual framework within which to grasp what global justice means today. Starting with Alf Hornborg’s explanatory theory of ‘unequal exchange of time and space’, and supplementing this with the consideration of inter-class flow of economic power, we analyse three ways in which disadvantage can be perpetrated in the dimension of time. We then show how those categories of temporal disadvantage broadly correspond with the three basic rights identified by Henry Shue as constituting the ‘morality of the depths’. Finally, we explain how ecological and temporal perspectives may be integrated in understanding the requirements of global justice. These show that the three types of temporal disadvantage can be mapped onto both an established understanding of basic human rights and a schema of normative relations in the use, occupation and command of ecological space.
