The proposed justification avoids problems that invalidate the familiar entitlement, utility, and interest-based justifications; interprets private property as necessary for controlling resources we need for our well-being; recognizes that the possession, uses, and limits of private property must be justified differently; and combines the defensible portions of the familiar but unsuccessful attempts at justification with a more complex account that combines the defensible portions of previous justificatory attempts with a new pluralistic approach that treats the right to private property as a conventional, defeasible, but indispensable right.

Classical natural law theory derives moral conclusions from the essentialist and teleological understanding of nature enshrined in classical metaphysics. The paper argues that this understanding of nature is as defensible today as it was in the days of Plato, Aristotle, Augustine, and Aquinas. It then shows how a natural law theory of the grounds and content of our moral obligations follows from this understanding of nature, and how a doctrine of natural rights follows in turn from the theory of natural law. With this background in place, the implications of the theory for questions about property rights and taxation are explored. It is argued that classical natural law theory entails the existence of a natural right of private property, and that this right is neither so strong as to support laissez faire libertarianism, nor so weak as to allow for socialism. Though the theory leaves much of the middle ground between these extremes open to empirical rather than moral evaluation, it is argued that there is a strong natural law presumption against social democratic policies and in favor of free enterprise.

The two main theses of “The Natural Right of Property” are: (i) that persons possess an original, non-acquired right not to be precluded from making extra-personal material their own (or from exercising discretionary control over what they have made their own); and (ii) that this right can and does take the form of a right that others abide by the rules of a (justifiable) practice of property which facilitates persons making extra-personal material their own (and exercising discretionary control over what they have made their own). I articulate some of the good reasons we have to affirm persons' possession of an original, non-acquired right of self-ownership and argue that the same good reasons support the ascription to persons of a natural right of property. I contrast an “inherent feature” conception of the actions through which (initial) rights over extra-personal objects arise with a “practice” conception of (initial) entitlement-generating actions. I argue that the fact that the natural right to property can and does take the form of persons' rights that others abide by the rules of a (justifiable) practice of property explains how there are many instances of (initial) entitlement generation which are not plausibly explained by those wed to the inherent feature conception of entitlement-generating actions and why there is a strong conventional dimension in the procedures through which persons acquire (initial) property rights.

When we’re trying to articulate principles of justice that we have reason to take seriously in a world like ours, one way to start is with an understanding of what our world is like, and of which institutional frameworks promote our thriving in communities and which do not. If we start this way, we can sort out alleged principles of justice by asking which ones license mutual expectations that promote our thriving and which ones do otherwise. This is an essay in the how and why of nonideal theory: in particular, how and why principles of property come first and principles of justice second. Ownership conventions, and property law as it develops under the pressures of case by case dispute resolution, tend to become touchstones for conflict mediation down through generations. They may be imperfect, retaining vestiges of adaptations to ancient problems that no longer exist, yet still they work, coordinating expectations so as to make it easier for people to live well together. A priori reasons for endorsing principles of justice generally are not good enough. A good enough reason would be something like this: to endorse this way of applying this principle in this kind of circumstance is to support institutional frameworks that position us to play positive sum games.

I present what I take to be the “classical” approach to property rights, in which property is basically a unitary concept: owners are the ones with the right to do, and prohibit others from doing, whatever there is to do with the thing owned, within the limits imposed by the rights of others to their things. I expound and defend the idea of “first acquisition” in more or less Lockean mode. I also point to the many difficulties of application of the general idea, leading to the need to negotiate at many points. For example, the vagueness of land ownership as we consider what goes on in the earth below or the sky above; to consideration of not just possible physical damages to others by virtue of ownership, but also aesthetic ones; and to the increasingly important area of intellectual property. I argue that the original idea continues to hold, though it underdetermines any number of specific issues.

Many libertarians believe that self-ownership is a separate matter from ownership of extra-personal property. “No-proviso” libertarians hold that property ownership should be free of any “fair share” constraints (e.g., the Lockean Proviso), on the grounds that the inability of the very poor to control property leaves their self-ownership intact. By contrast, left-libertarians hold that while no one need compensate others for owning himself, still property owners must compensate others for owning extra-personal property. What would a “self” have to be for these claims to be true? I argue that both of these camps must conceive of the boundaries of the self as including one's body but no part of the extra-personal world. However, other libertarians draw those boundaries differently, so that self-ownership cannot be separated from the right to control extra-personal property after all. In that case, property ownership must be subject to a fair share constraint, but that constraint does not require appropriators to pay compensation. This view, which I call “right libertarianism,” differs importantly from the other types primarily in its conception of the self, which I argue is independently more plausible.

Left-libertarianism is a version of Lockean libertarianism that combines the idea that each person is the full rightful owner of herself and the idea that each person should have the right to own a roughly equal amount of the world's resources. This essay argues against left-libertarianism. The specific target is an interesting form of left-libertarianism proposed by Michael Otsuka that is especially stringent in its equal world ownership claim. One criticism advanced is that there is more tension than Otsuka acknowledges between private ownership of self and equal ownership of the world. This emerges once one notices that self-ownership should not be conceived merely in a thin, formal way but also as a thicker substantive insistence on wide individual freedom. A second criticism is that in other respects the formal idea of self-ownership that Otsuka and other left-libertarians embrace is an extreme doctrine that merits rejection.

The basic question I want to ask is: can the exercise of private property rights abridge fundamental norms of democratic decision-making? And, under what conditions can it do so? To the extent that we view democratic decision making as required by justice, the issue is whether there is a deep tension between certain ways of exercising the rights of private property and that part of social justice that is characterized by democracy. To the extent that this tension holds, I will argue that commitment to democratic norms implies that private capitalist firms must cooperate with a democratic assembly and government in the pursuit of the aims of a democratic assembly even when this implies some diminution of the profits of the firms. The cooperation I have in mind goes beyond the norm of faithful compliance with the law. To be sure, there are limits to this requirement as we will see in the later part of the paper. To the extent that private capitalist firms fail to do this and partially undermine the pursuit of the aims of a democratic assembly, they act in a way that is incompatible with fundamental norms of democratic governance.

Luck egalitarians maintain that inequalities are always unjust when they are due to luck, but are not always unjust when they are due to choices for which the parties are responsible. In this paper, I argue that the two halves of this formula do not fit neatly together, and that we arrive at one version of luck egalitarianism if we begin with the notion of luck and interpret responsible choice in terms of its absence, but a very different version if we begin with the notion of responsible choice and interpret luck in terms of its absence. I argue, further, that the difference between the two versions is significant because many real-world inequalities fall precisely in the gap between them, and that attempts to adjudicate between them lead quickly to hard questions about the relation between equality and responsibility.

Justificatory liberalism is liberal in an abstract and foundational sense: it respects each as free and equal, and so insists that coercive laws must be justified to all members of the public. In this essay I consider how this fundamental liberal principle relates to disputes within the liberal tradition on “the extent of the state.” It is widely thought today that this core liberal principle of respect requires that the state regulates the distribution of resources or well-being to conform to principles of fairness, that all citizens be assured of employment and health care, that no one be burdened by mere brute bad luck, and that citizens' economic activities must be regulated to insure that they do not endanger the “fair value” of rights to determine political outcomes. I argue in this essay: (1) a large family of liberal views are consistent with the justificatory liberals project, from classical to egalitarian formulations (but not socialist ones); (2) overall, the justificatory project tilts in the direction of classical formulations.

Adam Smith raised a series of obstacles to effective large-scale social planning. In this paper, I draw these Smithian obstacles together to construct what I call the “Great Mind Fallacy,” or the belief that there exists some person or persons who can overcome the obstacles Smith raises. The putative scope of the Great Mind Fallacy is larger than one might initially suppose, which I demonstrate by reviewing several contemporary thinkers who would seem to commit it. I then address two ways the fallacy might be overcome, finding both wanting. I close the paper by suggesting that Smith's Great Mind Fallacy sheds interesting light on his “impartial spectator” standard of morality, including with respect to the specific issues of property and ownership.
