Sustainability is not a very useful parameter to evaluate the morality of an act, since it is an empty concept and it is linked with several heterogeneous matters. Meanwhile, the concept of sustainable development lacks specificity, as defined in terms of future needs, which are very difficult to predict. As a guide for our actions the concept of sustainable human development, formulated in terms of capabilities, philosophically grounded on an Aristotelian approach, will be more useful. This approach would also lead us to define a political theory for the common good, stating the centrality of the person in his entirety and complexity.
