The Rothbard Reader

The Nonaggression Axiom

The libertarian creed rests upon one central axiom: that no man or group of men may aggress against the person or property of anyone else. This may be called the “nonaggression axiom.” “Aggression” is defined as the initiation of the use or threat of physical violence against the person or property of anyone else. Aggression is therefore synonymous with invasion.

If no man may aggress against another; if, in short, everyone has the absolute right to be “free” from aggression, then this at once implies that the libertarian stands foursquare for what are generally known as “civil liberties”: the freedom to speak, publish, assemble, and to engage in such “victimless crimes” as pornography, sexual deviation, and prostitution (which the libertarian does not regard as “crimes” at all, since he defines a “crime” as violent invasion of someone else’s person or property). Furthermore, he regards conscription as slavery on a massive scale. And since war, especially modern war, entails the mass slaughter of civilians, the libertarian regards such conflicts as mass murder and therefore totally illegitimate.

All of these positions are now considered “leftist” on the contemporary ideological scale. On the other hand, since the libertarian also opposes invasion of the rights of private property, this also means that he just as emphatically opposes government interference with property rights or with the free-market economy through controls, regulations, subsidies, or prohibitions. For if every individual has the right to his own property without having to suffer aggressive depredation, then he also has the right to give away his property (bequest and inheritance) and to exchange it for the property of others (free contract and the free market economy) without interference. The libertarian favors the right to unrestricted private property and free exchange; hence, a system of “laissez-faire capitalism.”

In current terminology again, the libertarian position on property and economics would be called “extreme right wing.” But the libertarian sees no inconsistency in being “leftist” on some issues and “rightist” on others. On the contrary, he sees his own position as virtually the only consistent one, consistent on behalf of the liberty of every individual. For how can the leftist be opposed to the violence of war and conscription while at the same time supporting the violence of taxation and government control? And how can the rightist trumpet his devotion to private property and free enterprise while at the same time favoring war, conscription, and the outlawing of noninvasive activities and practices that he deems immoral? And how can the rightist favor a free market while seeing nothing amiss in the vast subsidies, distortions, and unproductive inefficiencies involved in the military-industrial complex?

While opposing any and all private or group aggression against the rights of person and property, the libertarian sees that throughout history and into the present day, there has been one central, dominant, and overriding aggressor upon all of these rights: the State. In contrast to all other thinkers, left, right, or in-between, the libertarian refuses to give the State the moral sanction to commit actions that almost everyone agrees would be immoral, illegal, and criminal if committed by any person or group in society. The libertarian, in short, insists on applying the general moral law to everyone, and makes no special exemptions for any person or group. But if we look at the State naked, as it were, we see that it is universally allowed, and even encouraged, to commit all the acts which even non-libertarians concede are reprehensible crimes. The State habitually commits mass murder, which it calls “war,” or sometimes “suppression of subversion”; the State engages in enslavement into its military forces, which it calls “conscription”; and it lives and has its being in the practice of forcible theft, which it calls “taxation.” The libertarian insists that whether or not such practices are supported by the majority of the population is not germane to their nature: that, regardless of popular sanction, War is Mass Murder, Conscription is Slavery, and Taxation is Robbery. The libertarian, in short, is almost completely the child in the fable, pointing out insistently that the emperor has no clothes.

Throughout the ages, the emperor has had a series of pseudo-clothes provided for him by the nation’s intellectual caste. In past centuries, the intellectuals informed the public that the State or its rulers were divine, or at least clothed in divine authority, and therefore what might look to the naïve and untutored eye as despotism, mass murder, and theft on a grand scale was only the divine working its benign and mysterious ways in the body politic. In recent decades, as the divine sanction has worn a bit threadbare, the emperor’s “court intellectuals” have spun ever more sophisticated apologias: informing the public that what the government does is for the “common good” and the “public welfare,” that the process of taxation-and-spending works through the mysterious process of the “multiplier” to keep the economy on an even keel, and that, in any case, a wide variety of governmental “services” could not possibly be performed by citizens acting voluntarily on the market or in society. All of this the libertarian denies: he sees the various apologias as fraudulent means of obtaining public support for the State’s rule, and he insists that whatever services the government actually performs could be supplied far more efficiently and far more morally by private and cooperative enterprise.

The libertarian therefore considers one of his prime educational tasks is to spread the demystification and desanctification of the State among its hapless subjects. His task is to demonstrate repeatedly and in depth that not only the emperor but even the “democratic” State has no clothes; that all governments subsist by exploitive rule over the public; and that such rule is the reverse of objective necessity. He strives to show that the very existence of taxation and the State necessarily sets up a class division between the exploiting rulers and the exploited ruled. He seeks to show that the task of the court intellectuals who have always supported the State has ever been to weave mystification in order to induce the public to accept State rule, and that these intellectuals obtain, in return, a share in the power and pelf extracted by the rulers from their deluded subjects.

Take, for example, the institution of taxation, which statists have claimed is in some sense really “voluntary.” Anyone who truly believes in the “voluntary” nature of taxation is invited to refuse to pay taxes and to see what then happens to him. If we analyze taxation, we find that, among all the persons and institutions in society, only the government acquires its revenues through coercive violence. Everyone else in society acquires income either through voluntary gift (lodge, charitable society, chess club) or through the sale of goods or services voluntarily purchased by consumers. If anyone but the government proceeded to “tax,” this would clearly be considered coercion and thinly disguised banditry. Yet the mystical trappings of “sovereignty” have so veiled the process that only libertarians are prepared to call taxation what it is: legalized and organized theft on a grand scale.

Property Rights

If the central axiom of the libertarian creed is nonaggression against anyone’s person and property, how is this axiom arrived at? What is its groundwork or support? Here, libertarians, past and present, have differed considerably. Roughly, there are three broad types of foundation for the libertarian axiom, corresponding to three kinds of ethical philosophy: the emotivist, the utilitarian, and the natural rights viewpoint. The emotivists assert that they take liberty or nonaggression as their premise purely on subjective, emotional grounds. While their own intense emotion might seem a valid basis for their own political philosophy, this can scarcely serve to convince anyone else. By ultimately taking themselves outside the realm of rational discourse, the emotivists thereby insure the lack of general success of their own cherished doctrine.

The utilitarians declare, from their study of the consequences of liberty as opposed to alternative systems, that liberty will lead more surely to widely approved goals: harmony, peace, prosperity, etc. Now no one disputes that relative consequences should be studied in assessing the merits or demerits of respective creeds. But there are many problems in confining ourselves to a utilitarian ethic. For one thing, utilitarianism assumes that we can weigh alternatives, and decide upon policies, on the basis of their good or bad consequences. But if it is legitimate to apply value judgments to the consequences of X, why is it not equally legitimate to apply such judgments to X itself? May there not be something about an act itself which, in its very nature, can be considered good or evil?

Another problem with the utilitarian is that he will rarely adopt a principle as an absolute and consistent yardstick to apply to the varied concrete situations of the real world. He will only use a principle, at best, as a vague guideline or aspiration, as a tendency which he may choose to override at any time. This was the major defect of the nineteenth-century English Radicals, who had adopted the laissez-faire view of the eighteenth-century liberals but had substituted a supposedly “scientific” utilitarianism for the supposedly “mystical” concept of natural rights as the groundwork for that philosophy. Hence the nineteenth-century laissez-faire liberals came to use laissez-faire as a vague tendency rather than as an unblemished yardstick, and therefore increasingly and fatally compromised the libertarian creed. To say that a utilitarian cannot be “trusted” to maintain libertarian principle in every specific application may sound harsh, but it puts the case fairly. A notable contemporary example is the free-market economist Professor Milton Friedman who, like his classical economist forebears, holds to freedom as against State intervention as a general tendency, but in practice allows a myriad of damaging exceptions, exceptions which serve to vitiate the principle almost completely, notably in the fields of police and military affairs, education, taxation, welfare, “neighborhood effects,” antitrust laws, and money and banking.

Let us consider a stark example: Suppose a society which fervently considers all redheads to be agents of the Devil and therefore to be executed whenever found. Let us further assume that only a small number of redheads exist in any generation—so few as to be statistically insignificant. The utilitarian-libertarian might well reason: “While the murder of isolated redheads is deplorable, the executions are small in number; the vast majority of the public, as non-redheads, achieves enormous psychic satisfaction from the public execution of redheads. The social cost is negligible, the social, psychic benefit to the rest of society is great; therefore, it is right and proper for society to execute the redheads.” The natural-rights libertarian, overwhelmingly concerned as he is for the justice of the act, will react in horror and staunchly and unequivocally oppose the executions as totally unjustified murder and aggression upon nonaggressive persons. The consequence of stopping the murders—depriving the bulk of society of great psychic pleasure—would not influence such a libertarian, the “absolutist” libertarian, in the slightest. Dedicated to justice and to logical consistency, the natural-rights libertarian cheerfully admits to being “doctrinaire,” to being, in short, an unabashed follower of his own doctrines.

Let us turn then to the natural-rights basis for the libertarian creed, a basis which, in one form or another, has been adopted by most of the libertarians, past and present. “Natural rights” is the cornerstone of a political philosophy which, in turn, is embedded in a greater structure of “natural law.” Natural law theory rests on the insight that we live in a world of more than one—in fact, a vast number—of entities, and that each entity has distinct and specific properties, a distinct “nature,” which can be investigated by man’s reason, by his sense perception and mental faculties. Copper has a distinct nature and behaves in a certain way, and so do iron, salt, etc. The species man, therefore, has a specifiable nature, as does the world around him and the ways of interaction between them. To put it with undue brevity, the activity of each inorganic and organic entity is determined by its own nature and by the nature of the other entities with which it comes in contact. Specifically, while the behavior of plants and at least the lower animals is determined by their biological nature or perhaps by their “instincts,” the nature of man is such that each individual person must, in order to act, choose his own ends and employ his own means in order to attain them. Possessing no automatic instincts, each man must learn about himself and the world, use his mind to select values, learn about cause and effect, and act purposively to maintain himself and advance his life. Since men can think, feel, evaluate, and act only as individuals, it becomes vitally necessary for each man’s survival and prosperity that he be free to learn, choose, develop his faculties, and act upon his knowledge and values. This is the necessary path of human nature; to interfere with and cripple this process by using violence goes profoundly against what is necessary by man’s nature for his life and prosperity. Violent interference with a man’s learning and choices is therefore profoundly “antihuman”; it violates the natural law of man’s needs.

Individualists have always been accused by their enemies of being “atomistic”—of postulating that each individual lives in a kind of vacuum, thinking and choosing without relation to anyone else in society. This, however, is an authoritarian straw man; few, if any, individualists have ever been “atomists.” On the contrary, it is evident that individuals always learn from each other, cooperate and interact with each other; and that this, too, is required for man’s survival. But the point is that each individual makes the final choice of which influences to adopt and which to reject, or of which to adopt first and which afterwards. The libertarian welcomes the process of voluntary exchange and cooperation between freely acting individuals; what he abhors is the use of violence to cripple such voluntary cooperation and force someone to choose and act in ways different from what his own mind dictates.

The most viable method of elaborating the natural-rights statement of the libertarian position is to divide it into parts, and to begin with the basic axiom of the “right to self-ownership.” The right to self-ownership asserts the absolute right of each man, by virtue of his (or her) being a human being, to “own” his or her own body; that is, to control that body free of coercive interference. Since each individual must think, learn, value, and choose his or her ends and means in order to survive and flourish, the right to self-ownership gives man the right to perform these vital activities without being hampered and restricted by coercive molestation.

Consider, too, the consequences of denying each man the right to own his own person. There are then only two alternatives: either (1) a certain class of people, A, have the right to own another class, B; or (2) everyone has the right to own his own equal quotal share of everyone else. The first alternative implies that while Class A deserves the rights of being human, Class B is in reality subhuman and therefore deserves no such rights. But since they are indeed human beings, the first alternative contradicts itself in denying natural human rights to one set of humans. Moreover, as we shall see, allowing Class A to own Class B means that the former is allowed to exploit, and therefore to live parasitically, at the expense of the latter. But this parasitism itself violates the basic economic requirement for life: production and exchange.

The second alternative, what we might call “participatory communalism” or “communism,” holds that every man should have the right to own his equal quotal share of everyone else. If there are two billion people in the world, then everyone has the right to own one two-billionth of every other person. In the first place, we can state that this ideal rests on an absurdity: proclaiming that every man is entitled to own a part of everyone else, yet is not entitled to own himself. Second, we can picture the viability of such a world: a world in which no man is free to take any action whatever without prior approval or indeed command by everyone else in society. It should be clear that in that sort of “communist” world, no one would be able to do anything, and the human race would quickly perish. But if a world of zero self-ownership and one hundred percent other ownership spells death for the human race, then any steps in that direction also contravene the natural law of what is best for man and his life on earth.

Finally, however, the participatory communist world cannot be put into practice. For it is physically impossible for everyone to keep continual tabs on everyone else, and thereby to exercise his equal quotal share of partial ownership over every other man. In practice, then, the concept of universal and equal other-ownership is utopian and impossible, and supervision and therefore control and ownership of others necessarily devolves upon a specialized group of people, who thereby become a ruling class. Hence, in practice, any attempt at communist rule will automatically become class rule, and we would be back at our first alternative.

The libertarian therefore rejects these alternatives and concludes by adopting as his primary axiom the universal right of self-ownership, a right held by everyone by virtue of being a human being. A more difficult task is to settle on a theory of property in nonhuman objects, in the things of this earth. It is comparatively easy to recognize the practice when someone is aggressing against the property right of another’s person: If A assaults B, he is violating the property right of B in his own body. But with nonhuman objects the problem is more complex. If, for example, we see X seizing a watch in the possession of Y we cannot automatically assume that X is aggressing against Y’s right of property in the watch; for may not X have been the original, “true” owner of the watch who can therefore be said to be repossessing his own legitimate property? In order to decide, we need a theory of justice in property, a theory that will tell us whether X or Y or indeed someone else is the legitimate owner.

Some libertarians attempt to resolve the problem by asserting that whoever the existing government decrees has the property title should be considered the just owner of the property. At this point, we have not yet delved deeply into the nature of government, but the anomaly here should be glaring enough: it is surely odd to find a group eternally suspicious of virtually any and all functions of government suddenly leaving it to government to define and apply the precious concept of property, the base and groundwork of the entire social order. It is particularly the utilitarian laissez-fairists who believe it most feasible to begin the new libertarian world by confirming all existing property titles; that is, property titles and rights as decreed by the very government that is condemned as a chronic aggressor.

Let us illustrate with a hypothetical example. Suppose that libertarian agitation and pressure has escalated to such a point that the government and its various branches are ready to abdicate. But they engineer a cunning ruse. Just before the government of New York state abdicates it passes a law turning over the entire territorial area of New York to become the private property of the Rockefeller family. The Massachusetts legislature does the same for the Kennedy family. And so on for each state. The government could then abdicate and decree the abolition of taxes and coercive legislation, but the victorious libertarians would now be confronted with a dilemma. Do they recognize the new property titles as legitimately private property? The utilitarians, who have no theory of justice in property rights, would, if they were consistent with their acceptance of given property titles as decreed by government, have to accept a new social order in which fifty new satraps would be collecting taxes in the form of unilaterally imposed “rent.” The point is that only natural-rights libertarians, only those libertarians who have a theory of justice in property titles that does not depend on government decree, could be in a position to scoff at the new rulers’ claims to have private property in the territory of the country, and to rebuff these claims as invalid. As the great nineteenth-century liberal Lord Acton saw clearly, the natural law provides the only sure ground for a continuing critique of governmental laws and decrees.1 What, specifically, the natural-rights position on property titles may be is the question to which we now turn.

We have established each individual’s right to self-ownership, to a property right in his own body and person. But people are not floating wraiths; they are not self-subsistent entities; they can only survive and flourish by grappling with the earth around them. They must, for example, stand on land areas; they must also, in order to survive and maintain themselves, transform the resources given by nature into “consumer goods,” into objects more suitable for their use and consumption. Food must be grown and eaten; minerals must be mined and then transformed into capital and then useful consumer goods, etc. Man, in other words, must own not only his own person, but also material objects for his control and use. How, then, should the property titles in these objects be allocated?

Let us take, as our first example, a sculptor fashioning a work of art out of clay and other materials; and let us waive, for the moment, the question of original property rights in the clay and the sculptor’s tools. The question then becomes: Who owns the work of art as it emerges from the sculptor’s fashioning? It is, in fact, the sculptor’s “creation,” not in the sense that he has created matter, but in the sense that he has transformed nature-given matter—the clay—into another form dictated by his own ideas and fashioned by his own hands and energy. Surely, it is a rare person who, with the case put thus, would say that the sculptor does not have the property right in his own product. Surely, if every man has the right to own his own body, and if he must grapple with the material objects of the world in order to survive, then the sculptor has the right to own the product he has made, by his energy and effort, a veritable extension of his own personality. He has placed the stamp of his person upon the raw material, by “mixing his labor” with the clay, in the phrase of the great property theorist John Locke. And the product transformed by his own energy has become the material embodiment of the sculptor’s ideas and vision. John Locke put the case this way:

every man has a property in his own person. This nobody has any right to but himself. The labour of his body and the work of his hands, we may say, are properly his. Whatsoever, then, he removes out of the state that nature hath provided and left it in, he hath mixed his labour with it, and joined it to something that is his own, and thereby makes it his property. It being by him removed from the common state nature placed it in, it hath by this labour something annexed to it that excludes the common right of other men. For this labour being the unquestionable property of the labourer, no man but he can have a right to what that is once joined to.2

As in the case of the ownership of people’s bodies, we again have three logical alternatives: (1) either the transformer, or “creator” has the property right in his creation; or (2) another man or set of men have the right in that creation, i.e., have the right to appropriate it by force without the sculptor’s consent; or (3) every individual in the world has an equal, quotal share in the ownership of the sculpture—the “communal” solution. Again, put baldly, there are very few who would not concede the monstrous injustice of confiscating the sculptor’s property, either by one or more others, or on behalf of the world as a whole. By what right do they do so? By what right do they appropriate to themselves the product of the creator’s mind and energy? In this clear-cut case, the right of the creator to own what he has mixed his person and labor with would be generally conceded. (Once again, as in the case of communal ownership of persons, the world communal solution would, in practice, be reduced to an oligarchy of a few others expropriating the creator’s work in the name of “world public” ownership.)

The main point, however, is that the case of the sculptor is not qualitatively different from all cases of “production.” The man or men who had extracted the clay from the ground and had sold it to the sculptor may not be as “creative” as the sculptor, but they too are “producers,” they too have mixed their ideas and their technological know-how with the nature-given soil to emerge with a useful product. They, too, are “producers,” and they too have mixed their labor with natural materials to transform those materials into more useful goods and services. These persons, too, are entitled to the ownership of their products. Where then does the process begin?

If every man owns his own person and therefore his own labor, and if by extension he owns whatever property he has “created” or gathered out of the previously unused, unowned, “state of nature,” then what of the last great question: the right to own or control the earth itself? In short, if the gatherer has the right to own the acorns or berries he picks, or the farmer the right to own his crop of wheat or peaches, who has the right to own the land on which these things have grown? It is at this point that Henry George and his followers, who have gone all the way so far with the libertarians, leave the track and deny the individual’s right to own the piece of land itself, the ground on which these activities have taken place. The Georgists argue that, while every man should own the goods which he produces or creates, since Nature or God created the land itself, no individual has the right to assume ownership of that land. Yet, if the land is to be used at all as a resource in any sort of efficient manner, it must be owned or controlled by someone or some group, and we are again faced with our three alternatives: either the land belongs to the first user, the man who first brings it into production; or it belongs to a group of others; or it belongs to the world as a whole, with every individual owning a quotal part of every acre of land. George’s option for the last solution hardly solves his moral problem: If the land itself should belong to God or Nature, then why as it more moral for every acre in the world to be owned by the world as a whole, than to concede individual ownership? In practice, again, it is obviously impossible for every person in the world to exercise effective ownership of his four-billionth portion (if the world population is, say, four billion) of every piece of the world’s land surface. In practice, of course, a small oligarchy would do the controlling and owning, and not the world as a whole.

But apart from these difficulties in the Georgist position, the natural-rights justification for the ownership of ground land is the same as the justification for the original ownership of all other property. For, as we have seen, no producer really “creates” matter; he takes nature-given matter and transforms it by his labor energy in accordance with his ideas and vision. But this is precisely what the pioneer—the “homesteader”—does when he brings previously unused land into his own private ownership. Just as the man who makes steel out of iron ore transforms that ore out of his know-how and with his energy, and just as the man who takes the iron out of the ground does the same, so does the homesteader who clears, fences, cultivates, or builds upon the land. The homesteader, too, has transformed the character of the nature-given soil by his labor and his personality. The homesteader is just as legitimately the owner of the property as the sculptor or the manufacturer; he is just as much a “producer” as the others.

Furthermore, if the original land is nature- or God-given then so are the people’s talents, health, and beauty. And just as all these attributes are given to specific individuals and not to “society,” so then are land and natural resources. All of these resources are given to individuals and not to “society,” which is an abstraction that does not actually exist. There is no existing entity called “society”; there are only interacting individuals. To say that “society” should own land or any other property in common, then, must mean that a group of oligarchs—in practice, government bureaucrats—should own the property, and at the expense of expropriating the creator or the homesteader who had originally brought this product into existence.

Moreover, no one can produce anything without the cooperation of original land, if only as standing room. No man can produce or create anything by his labor alone; he must have the cooperation of land and other natural raw materials.

Man comes into the world with just himself and the world around him—the land and natural resources given him by nature. He takes these resources and transforms them by his labor and mind and energy into goods more useful to man. Therefore, if an individual cannot own original land, neither can he in the full sense own any of the fruits of his labor. The farmer cannot own his wheat crop if he cannot own the land on which the wheat grows. Now that his labor has been inextricably mixed with the land, he cannot be deprived of one without being deprived of the other.

Moreover, if a producer is not entitled to the fruits of his labor, who is? It is difficult to see why a newborn Pakistani baby should have a moral claim to a quotal share of ownership of a piece of Iowa land that someone has just transformed into a wheatfield—and vice versa of course for an Iowan baby and a Pakistani farm. Land in its original state is unused and unowned. Georgists and other land communalists may claim that the whole world population really “owns” it, but if no one has yet used it, it is in the real sense owned and controlled by no one. The pioneer, the homesteader, the first user and transformer of this land, is the man who first brings this simple valueless thing into production and social use. It is difficult to see the morality of depriving him of ownership in favor of people who have never gotten within a thousand miles of the land, and who may not even know of he existence of the property over which they are supposed to have a claim.

The moral, natural-rights issue involved here is even clearer if we consider the case of animals. Animals are “economic land,” since they are original nature-given resources. Yet will anyone deny full title to a horse to the man who finds and domesticates it—is this any different from the acorns and berries that are generally conceded to the gatherer? Yet in land, too, some homesteader takes the previously “wild,” undomesticated land, and “tames” it by putting it to productive use. Mixing his labor with land sites should give him just as clear a title as in the case of animals. As Locke declared: “As much land as a man tills, plants, improves, cultivates, and can use the product of, so much is his property. He by his labour does, as it were, enclose it from the common.”3
