Over the past few decades, there has been increasing interest in left- libertarianism, which holds (roughly) that agents fully own themselves and that natural resources (land, minerals, air, and the like) belong to everyone in some egalitarian sense. Left-libertarianism agrees with the more familiar right-libertarianism about self-ownership, but radically disagrees with it about the power to acquire ownership of natural resources. Merely being the first person to claim, discover, or mix labor with an unappropriated natural resource does not—left-libertarianism insists—generate a full private property right in that natural resource. Left-libertarianism seems promising because it recognizes both strong individual rights of liberty and security and also grounds a strong demand for some kind of material equality. It seems, that is, to be a plausible a form of liberal egalitarianism. In a recent review essay of a two-volume anthology on left-libertarianism (edited by two of us), Barbara Fried has insightfully laid out most of the core issues that confront left-libertarianism.1 We are each left-libertarians, and we would like to take this opportunity to address some of the general issues that she raises. We shall focus, as Fried does much of the time, on the question of whether left-libertarianism is a well-defined and distinct alternative to existing forms of liberal egalitarianism. More specifically, we shall address the following fundamental issues raised by Fried (and others): (1) Does the notion of self-ownership have any determinate content? (2) What is the relation between self-ownership and world ownership? (3) How is left-libertarianism different from other forms of liberal egalitarianism (e.g., those of Rawls and Dworkin)? First, however, we shall set the context by providing some general background on left-libertarianism.

For many persons, ‘Holocaust‐abomination’is a fixed point on their moral compass: if anything can be evil, it was. Yet at least one of the justifications deployed by its perpetrators (the eugenics argument) invokes widely‐held values concerning human health and procreation. Hence persons endorsing many current activities based on those values (e.g. genetic counselling) have been charged with being on a morally deplorable slippery slope. This paper sketches the necessary structure of a moral position capable of consistently embracing those values without placing its occupants on that slippery slope.

A rational moral code must satisfy the condition of completeness. This same condition applies to a set of moral rights, where it takes the form of requiring that all the rights in that set be compossible: that their respective correlatively entailed duties be jointly fulfillable. Such joint fulfillability is guaranteed only by a set of fully differentiated individual domains. And if moral rights are to play any independent role in moral reasoning - any role logically independent of the values that bring persons into conflict - those domains must be determined by rules which are not derived from those values.

In a paper published in this journal we proposed a method for resolving disputed land claims between two parties (Steiner and Wolff: 2003). In essence the proposal is to hold an auction between the disputants in which the land is given to the higher bidder, but the receipts of the auction to the under-bidder. We claimed that under such circumstances both parties can walk away happy: the higher bidder happy to pay the price bid for the land; the under-bidder happier to have the receipts of the auction when the alternative is to pay for the land at a higher price.
