Abstract

This paper addresses a theory of intergenerational justice that we refer to as “needs-based sufficientarianism”. According to needs-based sufficientarianism, the present generation ought to enable future generations to meet their basic needs — for example, their needs for drinkable water, food and health care. Our aim is to explain and defend this theory in a programmatic way. First, we introduce what we regard as the most plausible variant of needs-based sufficientarianism. Then we argue that this variant is superior to several alternative ways of thinking about intergenerational justice. In particular, we defend basic needs as the currency of intergenerational justice and sufficiency as its principle. Our arguments for these claims are neither fully comprehensive nor fully conclusive. Yet, we hope that they suffice to show that needs-based sufficientarianism is a major contender, with significant pro tanto advantages over other views.
