Abstract

Many valuable natural resources are found outside current territorial limits, for example, on the Moon and in the deep sea. As technology advances, these resources become more accessible. I argue that the claim that all humanity owns these resources is insupportable if taken literally. Because they are truly unowned, we need to develop a principle of justice in acquisition which describes the procedure that must be followed to obtain property rights to these unowned objects. I conclude with a tentative development of such a principle based on the moral ideals of fairness, freedom, and the maximization of the common good.
