In 1987, the Brundtland Commission urged nations to improve present conditions without compromising the ability of future generations to meet their needs. Against the background of this appeal for sustainable development, there is a call for intergenerational justice, under a sufficientarian framework. Despite their strong relation, we claim that, to some degree, intergenerational sufficientarianism disregards relevant sustainability notions. This neglect undermines intergenerational sufficientarianism in the context of sustainability, here operationalized as sustainable development. In response, we propose the concept of irreplaceable (...) goods as a necessary bridge between the two frameworks. Simultaneously, we stress the need for scholars to consider sufficientarianism as a valid alternative to egalitarianism for achieving resource justice. To harmonize intergenerational sufficientarianism and sustainability, we firstly delineate sustainability theoretical notions that influence fair distributive futures. Secondly, we incorporate those sustainability constraints into the conceptual background of intergenerational sufficientarianism. We also establish the concept of irreplaceable goods as a pivot and anchor for further theoretical development on the sufficient well-being of future generations. Finally, we discuss the implications of this concept in terms of expenditure and investment by contemporary people. With the proposed adjustments, we advocate that intergenerational sufficientarianism is a robust framework to deliver just futures. (shrink)

According to the so-called Classical Theory, concepts are mentally represented by individually necessary and jointly sufficient application conditions. One of the principal empirical objections against this view stems from evidence that people judge some instances of a concept to be more typical than others. In this paper we present and discuss four empirical studies that investigate the extent to which this ‘typicality effect’ holds for the concept of basic needs. Through multiple operationalizations of typicality, our studies yielded evidence for a (...) strong effect of this kind: Participants tended to recall the same core examples of the concept in a free-listing task. They judged some basic needs to be more typical than others. The items that were judged to be more typical were listed more frequently in the free-listing task. These items were listed earlier on in the free-listing task. Typical basic needs, as well as non needs, were classified faster than atypical basic needs in a reaction time study. These findings suggest that the concept of basic needs may have a non-classical structure. If so, the quest for a simple and robust intensional analysis of the concept may be futile. (shrink)
