In [[economics]] and [[political economy]], there are three broad forms of property: [[private property]], [[public property]], and [[collective property]] (or ''cooperative propert''y).<ref>{{Cite book |title=Comparing Economic Systems in the Twenty-First Century |year=2003 |last1=Gregory |first1=Paul R. |last2=Stuart |first2=Robert C. |location=Boston |publisher=Houghton Mifflin |isbn=0-618-26181-8 |page=27 |quote=There are three broad forms of property ownership—private, public, and collective (cooperative).}}</ref> Property may be jointly owned by more than one party equally or unequally, or according to simple or complex agreements; to distinguish ownership and easement from rent, there is an expectation that each party's will with regard to the property be clearly defined and unconditional.{{citation needed|date=August 2013}}. The parties may expect their wills to be unanimous, or alternatively each may expect their own will to be sufficient when no opportunity for dispute exists.

In [[Law of the United States|American law]], the first [[Restatements of the Law|Restatement]] defines property as anything, tangible or intangible, whereby a legal relationship between persons and the State enforces a possessory interest or legal title in that thing. This mediating relationship between individual, property, and State is called a property regime.<ref>{{cite web |last1=Pellissary |first1=Sony |last2=Dey Biswas |first2=Sattwick |title=Emerging Property Regimes in India: What it Holds for the Future of Socio-economic Rights? |url=https://www.irma.ac.in/pdf/randp/1175_17402.pdf |website=www.irma.ac.in |publisher=Institute of Rural Management Anand |access-date=26 October 2021 |date=November 2012}}</ref>

In [[sociology]] and [[anthropology]], property is often defined as a relationship between two or more individuals and an object, in which at least one of these individuals holds a bundle of rights over the object. The distinction between collective and private property is regarded as confusion, since different individuals often hold differing rights over a single object.<ref>{{cite book |last1=Graber |first1=David |author1-link=David Graeber |title=Toward an Anthropological Theory of Value |title-link=Toward an Anthropological Theory of Value |year=2002 |publisher=Palgrave |location=New York |isbn=978-0-312-24044-8 |page=9}}</ref><ref>Max Planck Institute for Social Anthropology, Property in Anthropology, {{cite web |url=http://www.eth.mpg.de/cms/en/research/d2/completed/property/moreinfo/ |title=Max Planck Institute for Social Anthropology |access-date=2015-01-15 |url-status=dead |archive-url=https://web.archive.org/web/20150116101316/http://www.eth.mpg.de/cms/en/research/d2/completed/property/moreinfo/ |archive-date=2015-01-16 }}</ref>

Types of property include [[realty|real property]] (the combination of land and any improvements to or on the ground), [[personal property]] (physical possessions belonging to a person), private property (property owned by legal persons, business entities or individual natural persons), public property (State-owned or publicly owned and available possessions) and [[intellectual property]]—including exclusive rights over artistic creations and inventions. However, the latter is not always widely recognized or enforced. An article of property may have physical and incorporeal parts. A [[title (property)|title]], or a right of [[ownership]], establishes the relation between the property and other persons, assuring the owner the right to dispose of the property as the owner sees fit.{{citation needed|date=October 2011}} The unqualified term "property" is often used to refer specifically to real property.

==Overview==
{{property law}}
Property is often defined by the code of the local [[sovereignty]] and protected wholly or – more usually, partially – by such entity, the owner being responsible for any remainder of protection. The [[Standard of proof|standards of the proof]] concerning proofs of ownerships are also addressed by the code of the local sovereignty, and such entity plays a role accordingly, typically [[Recorder of deeds|somewhat managerial]]. Some philosophers{{who|date=April 2012}} assert that property [[rights]] arise from [[Convention (norm)|social convention]], while others find justifications for them in [[morality]] or in [[natural law]].{{citation needed|date=April 2023}}

Various scholarly disciplines (such as [[law]], [[economics]], [[anthropology]] or [[sociology]]) may treat the concept more systematically, but definitions vary, most particularly when involving [[contract]]s. [[Positive law]] defines such rights, and the [[judiciary]] can adjudicate and enforce property rights.

According to [[Adam Smith]] (1723–1790), the expectation of profit from "improving one's stock of capital" rests on private-property rights.<ref>{{cite book |date=2004 |url=https://books.google.com/books?id=9Kw5vLbYq-4C&q=Adam+Smith,+the+expectation+of+profit+from+%22improving+one%27s+stock+of+capital%22+rests+on+private+property+rights&pg=PA355 |title=Understanding the Global Economy, Howard Richards (p. 355) |publisher=Peace Education Books |isbn= 978-0-9748961-0-6 }}</ref> [[Capitalism]] has as a central assumption that property rights encourage their holders to develop the property, generate [[wealth]], and efficiently allocate [[factors of production|resources]] based on the operation of markets. From this has evolved the modern conception of property as a right enforced by positive law, in the expectation that this will produce more wealth and better standards of living. However, Smith also expressed a very critical view of the effects of property laws on inequality:<ref>{{cite book |access-date=2011-12-15 |url= https://books.google.com/books?id=jH5bTCHDYTgC |title=An inquiry into the nature and causes of the wealth of nations | page = 177 |publisher=Hackett Publishing Company|isbn=0-87220-204-6 |year=1993 }}</ref>
{{blockquote|Wherever there is a great property, there is great inequality … Civil government, so far as it is instituted for the security of property, is in reality instituted for the defense of the rich against the poor, or of those who have some property against those who have none at all.}}

In his 1881 text "The Common Law", [[Oliver Wendell Holmes Jr.|Oliver Wendell Holmes]] describes property as having two fundamental aspects.<ref>{{Cite web |title=The Common Law, by Oliver Wendell Holmes, Jr. |url=https://www.gutenberg.org/files/2449/2449-h/2449-h.htm |access-date=2025-05-20 |website=www.gutenberg.org}}</ref> The first, possession, can be defined as control over a resource based on the practical inability to contradict the ends of the possessor. The second title is the expectation that others will recognize rights to control resources, even when not in possession. He elaborates on the differences between these two concepts and proposes a history of how they came to be attached to persons, as opposed to families or entities such as the church.
* [[Classical liberalism]] subscribes to the [[labor theory of property]]. Its proponents hold that individuals each own their own life; it follows that one must acknowledge the products of that life and that those products can be traded in free exchange with others.

:: "Every man has a property in his person. This nobody has a right to, but himself." ([[John Locke]], "[[Second Treatise on Civil Government]]", 1689)

:: "The reason why men enter into society is the preservation of their property." ([[John Locke]], "Second Treatise on Civil Government", 1689)

:: "Life, liberty, and property do not exist because men have made laws. On the contrary, it was the fact that life, liberty, and property existed beforehand that caused men to make laws in the first place." ([[Frédéric Bastiat]], [[The Law (1849 book)|''The Law'']], 1850)
* [[Conservatism]] subscribes to the concept that freedom and property are closely linked - building on traditions of thought that property guarantees freedom<ref>

 |quote                = [ A quote from 1768] demonstrates again the centrality of property ownership to the colonists' concept of freedom: property was what made men free, and not 'slaves' or 'like beasts subdued by whips and goads.' [...] Property had the potential of creating independence for the individual because, by utilizing and shaping the earth through one's labor and having exclusive (property) right to it, one created the means to act freely in the world. [...] In a letter that Thomas Jefferson wrote [...] thirty years after the American Revolution, he also expressed the importance of private property if an individual was to be free [...]. [...] Owning landed property could satisfy the wants and needs of the individual, this made him or her free.
}}
</ref> The more widespread the possession of the private property, conservatism propounds, the more stable and productive a state or nation is. Conservatives maintain that the economic leveling of property, especially of the forced kind, is not economic progress.

:: "Separate property from private possession and [[Leviathan]] becomes master of all... Upon the foundation of private property, great civilizations are built. The conservative acknowledges that the possession of property fixes certain duties upon the possessor; he accepts those moral and legal obligations cheerfully." ([[Russell Kirk]], ''The Politics of Prudence'', 1993)
* [[Socialism]]'s fundamental principles center on a critique of this concept, stating (among other things) that the cost of defending property exceeds the returns from private property ownership and that, even when property rights encourage their holders to develop their property or generate wealth, they do so only for their benefit, which may not coincide with advantage to other people or society at large.
* [[Libertarian Socialism]] generally accepts property rights with a short abandonment period. In other words, a person must make (more-or-less) continuous use of the item or else lose ownership rights. This is usually referred to as "possession property" or "[[usufruct]]." Thus, in this usufruct system, absentee ownership is illegitimate, and workers own the machines or other equipment they work with.
* [[Communism]] argues that only [[common ownership]] of the [[means of production]] will assure the minimization of unequal or unjust outcomes and the maximization of benefits and that; therefore humans should abolish private ownership of [[capital (economics)|capital]] (as opposed to property).

Both communism and some forms of socialism have also upheld the notion that private ownership of capital is inherently illegitimate. This argument centers on the idea that private ownership of capital always benefits one [[Social class|class]] over another, giving rise to domination through this privately owned capital. Communists do not oppose personal property that is "hard-won, self-acquired, self-earned" (as "[[The Communist Manifesto]]" puts it) by members of the [[proletariat]]. Both socialism and communism distinguish carefully between private ownership of capital (land, factories, resources, etc.) and private property (homes, material objects, and so forth).

=== Types of property ===
Most [[legal system]]s distinguish between different types of property, especially between land ([[immovable property]], [[estate in land]], [[real estate]], [[real property]]) and all other forms of property—[[goods]] and [[Personal property|chattels]], [[movable property]] or [[personal property]], including the [[Face value|value of legal tender]] if not the [[Legal tender|legal tender itself]], as the [[Currency#Control and production|manufacturer]] rather than the possessor might be the owner. They often distinguish [[tangible property|tangible]] and [[intangible property]]. One categorization scheme specifies three species of property: land, improvements (immovable man-made things), and personal property (movable man-made things).<ref>{{Cite web|url=https://www.law.cornell.edu/cfr/text/13/314.1|title=13 Code of Federal Regulations § 314.1 ("Definitions")|access-date=2021-05-09|website=Cornell University's Legal Information Institute|author-link=Economic Development Administration|quote=Property means Real Property, Personal Property and mixed Property. [...] Real Property means any land, whether raw or improved, and includes structures, fixtures, appurtenances and other permanent improvements, excluding moveable machinery and equipment. Real Property includes land that is served by the construction of Project infrastructure (such as roads, sewers, and water lines) where the infrastructure contributes to the value of such land as a specific purpose of the Project.}}</ref>

In [[common law]], [[real property]] ([[immovable property]]) is the combination of [[Rights|interests]] in land and improvements thereto, and [[personal property]] is interest in movable property. Real property rights are rights relating to the land. These rights include ownership and usage. Owners can grant rights to persons and entities in the form of [[lease]]s, [[license]]s, and [[easement]]s.

Throughout the last centuries of the [[2nd millennium|second millennium]], with the development of more complex theories of property, the concept of personal property had become divided{{By whom|date=May 2013}} into tangible property (such as [[Automobile|cars]] and [[clothing]]) and intangible property (such as [[financial asset]]s and related rights, including [[capital stock|stock]]s and [[Bond (finance)|bonds]]; [[intellectual property]], including [[patent]]s, [[copyright]]s and [[trademark]]s; [[digital file]]s; [[communication channel]]s; and certain forms of [[identifier]], including [[domain name|Internet domain names]], some forms of [[network address]], some forms of [[Call sign|handle]] and again trademarks).

Treatment of intangible property is such that an article of property is, by law or otherwise by traditional conceptualization, subject to expiration even when [[Inheritance|inheritable]], which is a key distinction from tangible property. Upon expiration, the property, if of the intellectual category, becomes a part of [[public domain]], to be used by but not owned by anybody, and possibly used by more than one party simultaneously due to the inapplicability of [[scarcity]] to intellectual property. Whereas things such as communications channels and pairs of electromagnetic spectrum bands and signal transmission power can only be used by a single party at a time, or a single party in a divisible context, if owned or used. Thus far or usually, those are not considered property, or at least not private property, even though the party bearing right of exclusive use may transfer that right to another.

In many societies the [[human body]] is considered property of some kind or other. The question of the ownership and rights to one's body arise in general in the discussion of [[human rights]], including the specific issues of [[slavery]], [[conscription]], rights of children under the [[age of majority]], [[marriage]], [[abortion]], [[prostitution]], [[drugs]], [[euthanasia]] and [[organ donation]].

==Issues in property theory==

=== Principle ===
The two major justifications are given for the original property, or the [[homestead principle]], are effort and scarcity. [[John Locke]] emphasized effort, "mixing your labor"<ref>{{cite web |url=http://www.constitution.org/jl/2ndtr05.htm |title=John Locke: Second Treatise of Civil Government: Chapter 5 |access-date=14 May 2015 |url-status=dead |archive-url=https://web.archive.org/web/20150613041353/http://www.constitution.org/jl/2ndtr05.htm |archive-date=Jun 13, 2015 |website=Constitution.org }}</ref> with an object, or clearing and cultivating virgin land. [[Benjamin Tucker]] preferred to look at the [[Telos (philosophy)|telos]] of property, i.e., what is the purpose of property? His answer: to solve the scarcity problem. Only when items are relatively scarce concerning people's desires, do they become property.<ref>{{cite web |url=http://www.zetetics.com/mac/libdebates/ch6intpr.html |title=Intellectual Property {{!}} Copyright and Patent in Benjamin Tucker's periodical Liberty |first=Wendy |last=McElroy |date=11 May 2008 |access-date=14 May 2015 |url-status=dead |archive-url=https://web.archive.org/web/20080706115752/http://www.zetetics.com/mac/libdebates/ch6intpr.html |archive-date=6 July 2008 }}</ref>  For example, hunter-gatherers did not consider land to be property, since there was no shortage of land.  Agrarian societies later made arable land property, as it was scarce. For something to be economically scarce, it must necessarily have the "exclusivity property"—that use by one person excludes others from using it. These two justifications lead to different conclusions on what can be property. [[Intellectual property]]—incorporeal things like ideas, plans, orderings and arrangements (musical compositions, novels, computer programs)—are generally considered valid property to those who support an effort justification, but invalid to those who support a scarcity justification, since the things don't have the exclusivity property (however, those who support a scarcity justification may still support other "intellectual property" laws such as [[Copyright]], as long as these are a subject of [[contract]] instead of government arbitration). Thus even ardent [[propertarian]]s may disagree about IP.<ref>{{cite web |url=http://praxeology.net/anticopyright.htm |title=Molinari Institute – Anti-Copyright Resources |access-date=14 May 2015 |website=Praxeology.net}}</ref> By either standard, one's body is one's property.

From some [[anarchism|anarchist]] points of view, the validity of property depends on whether the "property right" requires enforcement by the State. Different forms of "property" require different amounts of enforcement: [[intellectual property]] requires a great deal of state intervention to enforce, ownership of distant physical property requires quite a lot, ownership of carried objects requires very little. In contrast, requesting one's own body requires absolutely no state intervention. So some anarchists don't believe in property at all.

Many things have existed that did not have an [[owner]], sometimes called the [[commons]]. The term "commons," however, is also often used to mean something entirely different: "general collective ownership"—i.e. [[common ownership]]. Also, the same term is sometimes used by [[Statism|statists]] to mean government-owned property that the general public is allowed to access ([[public property]]). Law in all societies has tended to reduce the number of things not having clear owners. Supporters of property rights argue that this enables better protection of scarce resources due to the [[tragedy of the commons]]. At the same time, critics say that it leads to the 'exploitation' of those resources for personal gain and that it hinders taking advantage of potential [[network effects]]. These arguments have differing validity for different types of "property"—things that are not scarce are, for instance, not subject to the [[tragedy of the commons]]. Some apparent critics advocate general collective ownership rather than ownerlessness.

Things that do not have owners include: [[idea]]s (except for [[intellectual property]]), [[seawater]] (which is, however, protected by anti-pollution laws), parts of the [[seafloor]] (see the [[United Nations Convention on the Law of the Sea]] for restrictions), gases in [[Earth's atmosphere]], animals in the wild (although in most nations, animals are tied to the land. In the [[United States]] and [[Canada]], wildlife is generally defined in statute as property of the State. This public ownership of wildlife is referred to as the North American Model of Wildlife Conservation and is based on The Public Trust Doctrine.<ref>{{cite web |url=http://joomla.wildlife.org/index.php?id=171&option=com_content&task=view |title=The North American Model of Wildlife Conservation and Public Trust Doctrine |url-status=dead |access-date=2012-08-19 |archive-url=https://web.archive.org/web/20120119010211/http://joomla.wildlife.org/index.php?id=171&option=com_content&task=view |archive-date=2012-01-19 |website=The Wildlife Society }}</ref>), celestial bodies and outer space, and land in [[Antarctica]].

The nature of children under the [[age of majority]] is another contested issue here. In ancient societies, children were generally considered the property of their parents. However, children in most modern communities theoretically own their bodies but are not regarded as competent to exercise their rights. Their parents or [[legal guardian|guardians]] are given most of the fundamental rights of control over them.

Questions regarding the nature of ownership of the body also come up in the issue of [[abortion]], [[drugs]], and [[euthanasia]].

In many ancient legal systems (e.g., early [[Roman law]]), religious sites (e.g. [[temple]]s) were considered property of the [[God]] or gods they were devoted to. However, [[religious pluralism]] makes it more convenient to have sacred sites owned by the [[spiritual body]] that runs them.

[[Intellectual property]] and air ([[airspace]], [[no-fly zone]], pollution laws, which can include tradable [[emissions trading|emissions rights]]) can be property in some senses of the word.

Ownership of land can be held separately from the ownership of rights over that land, including sporting rights,<ref>{{cite web |url=http://www.basc.org.uk/media/2001_definition_of_sporting_rights.pdf |title=Definition of sporting rights |website=BASC |access-date=2007-12-31 |url-status=dead |archive-url=https://web.archive.org/web/20080227003852/http://www.basc.org.uk/media/2001_definition_of_sporting_rights.pdf |archive-date=2008-02-27 }}</ref> [[mineral rights]], development rights, [[air rights]], and such other rights as may be worth segregating from simple land ownership.

=== Ownership ===
{{Main|Ownership}}
Ownership laws may vary widely among countries depending on the nature of the property of interest (e.g., firearms, real property, personal property, animals). Persons can own property directly. In most societies [[Juristic person|legal entities]], such as [[corporations]], [[Trust law|trusts]] and nations (or governments) own property.

In many countries women have limited access to property following restrictive inheritance and family laws, under which only men have actual or formal rights to own property.

In the Inca empire, the dead emperors, considered gods, still controlled property after death.<ref>Mckay, John P. , 2004, "A History of World Societies". Boston: Houghton Mifflin Company</ref>

=== Government interference ===
In 17th-century [[England]], the legal directive that nobody may enter a home (which in the 17th century would typically have been male-owned) unless by the owner's invitation or consent, was established as common law in Sir [[Edward Coke]] 's "[[Institutes of the Lawes of England]]". "For a man's house is his castle, et domus sua cuique est tutissimum refugium [and each man's home is his safest refuge]." It is the origin of the famous dictum, "an Englishman's home is his castle".<ref name= "Pitt">{{cite web |title=An Englishman's home is his castle |url=https://www.phrases.org.uk/meanings/an-englishmans-home-is-his-castle.html |website=Phrases.org.uk |access-date=6 December 2018}}</ref> The ruling enshrined into law what several English writers had espoused in the 16th century.<ref name=" Pitt"/> Unlike the rest of Europe the British had a proclivity towards owning their own homes.<ref name=" Pitt"/> British Prime Minister [[William Pitt, 1st Earl of Chatham]] defined the meaning of castle in 1763, "The poorest man may in his cottage bid defiance to all the forces of the crown. It may be frail – its roof may shake – the wind may blow through it – the storm may enter – the rain may enter – but the King of England cannot enter."<ref name=" Pitt"/>

That principle was carried to the United States. Under U.S. law, the principal limitations on whether and the extent to which the State may interfere with property rights are set by the Constitution. The [[Takings clause]] requires that the government (whether State or federal—for the 14th Amendment's due process clause imposes the 5th Amendment's takings clause on state governments) may take private property only for a public purpose after exercising due process of law, and upon making "just compensation." If an interest is not deemed a "property" right or the conduct is merely an intentional tort, these limitations do not apply, and the doctrine of [[sovereign immunity]] precludes relief.<ref>See, for example, "[[United States v. Willow River Power Co.]]" (not a property right because the force of law not behind it); "[[Schillinger v. the United States]]," 155 U.S. 163 (1894) (patent infringement is a tort, not taking of property); "Zoltek Corp. v. United States", 442 F.3d 1345 (Fed. Cir. 2006).</ref> Moreover, if the interference does not almost completely make the property valueless, the interference will not be deemed a taking but instead a mere regulation of use.<ref>" Penn Central Transportation Co. v. City of New York", 438 U.S. 104 (1978).</ref> On the other hand, some governmental regulations of property use have been deemed so severe that they have been considered "[[regulatory taking]]s."<ref>See ''United States v. Riverside Bayview Homes'', 474 U.S. 121 (1985).</ref> Moreover, conduct is sometimes deemed only a nuisance, or another tort has been held a taking of property where the conduct was sufficiently persistent and severe.<ref>''United States v. Causby'', 328 U.S. 256 (1946).</ref>

== Theories ==
There exist many theories of property. One is the relatively rare [[first possession theory of property]], where ownership of something is seen as justified simply by someone seizing something before someone else does.<ref>"Property". Graham Oppy. "The shorter Routledge encyclopedia of philosophy." Editor [[Edward Craig (philosopher)|Edward Craig]]. Routledge, 2005, p. 858</ref> Perhaps one of the most popular is the [[natural rights]] definition of property rights as advanced by [[John Locke]]. Locke advanced the theory that God granted dominion over nature to man through Adam in the book of Genesis. Therefore, he theorized that when one mixes one's labor with nature, one gains a relationship with that part of nature with which the labor is mixed, subject to the limitation that there should be "enough, and as good, left in common for others." (see [[Lockean proviso]])<ref>{{cite web |title=The Second Treatise of Civil Government |year=1690 |first=John |last=Locke |url=http://www.constitution.org/jl/2ndtr05.txt |access-date=2010-06-26}}</ref>

In his [[encyclical letter]] ''[[Rerum novarum]]'' (1891), [[Pope Leo XIII]] wrote, "It is surely undeniable that, when a man engages in remunerative labor, the impelling reason and motive of his work is to obtain property, and after that to hold it as his very own."<ref>Leo XIII (1891), [https://www.vatican.va/content/leo-xiii/en/encyclicals/documents/hf_l-xiii_enc_15051891_rerum-novarum.html Rerum novarum] ''On the Rights and Duties of Capital and Labor'', paragraph 5, accessed 30 January 2023</ref>

Anthropology studies the diverse ownership systems, rights of use and transfer, and possession<ref>Hann, Chris "[http://www.ingentaconnect.com/search/article?title=anthropology&title_type=tka&year_from=1998&year_to=2007&database=1&pageSize=20&index=14 A new double movement? Anthropological perspectives on property in the age of neoliberalism]" Socio-Economic Review, Volume 5, Number 2, April 2007, pp. 287–318(32)</ref> under the term "theories of property". As mentioned, western legal theory is based on the owner of property being a legal person. However, not all property systems are founded on this basis.

In every culture studied, ownership and possession are the subjects of custom and regulation, and "law" is where the term can meaningfully be applied. Many tribal cultures balance individual rights with the laws of collective groups: tribes, families, associations, and nations. For example, the 1839 Cherokee Constitution frames the issue in these terms:

{{blockquote|Sec. 2. The lands of the Cherokee Nation shall remain common property. Still, the improvements made thereon, and in possession of the citizens respectively who made, or may rightfully own them:  Provided, that the citizens of the Nation possessing the exclusive and indefeasible right to their improvements, as expressed in this article, shall possess no right or power to dispose of their improvements, in any manner whatever, to the United States, individual States, or individual citizens thereof; and that, whenever any citizen shall remove with his effects out of the limits of this Nation, and become a citizen of any other government, all his rights and privileges as a citizen of this Nation shall cease: Provided, nevertheless, That the National Council shall have power to re-admit, by law, to all the rights of citizenship, any such person or persons who may, at any time, desire to return to the Nation, on memorializing the National Council for such readmission.}}

Communal property systems describe ownership as belonging to the entire social and political unit. Common ownership in a hypothetical [[communist society]] is distinguished from primitive forms of common property that have existed throughout history, such as [[Communalism (Bookchin)|Communalism]] and [[primitive communism]], in that communist common ownership is the outcome of social and technological developments leading to the [[Post-scarcity|elimination of material scarcity]] in society.<ref>{{Cite journal|last=Engels|first=Friedrich|title=The Principles of Communism|url=https://www.marxists.org/archive/marx/works/1847/11/prin-com.htm|journal=Vorwärts|via=Marxist Internet Archive}}</ref>

Corporate systems describe ownership as being attached to an identifiable group with an identifiable responsible individual. The Roman property law was based on such a corporate system. In a well-known paper that contributed to the creation of the field of [[law and economics]] in the late 1960s, the American scholar [[Harold Demsetz]] described how the concept of property rights makes social interactions easier:

{{Blockquote
|text=In the world of [[Robinson Crusoe]], property rights play no role. Property rights are an instrument of society and derive their significance from the fact that they help a man form those expectations which he can reasonably hold in his dealings with others. These expectations find expression in society's laws, customs, and more. An owner of property rights possesses the consent of fellowmen to allow him to act in particular ways. An owner expects the community to prevent others from interfering with his actions, provided that these actions are not prohibited in the specifications of his rights.
|author=Harold Demsetz (1967)
|source="Toward a Theory of property Rights", ''The American Economic Review'' 57(2), p. 347.<ref>Cited in Merrill & Smith (2017), pp. 238–39.</ref>
}}

Different societies may have other theories of property for differing types of ownership. For example, [[Pauline Peters]] argued that property systems are not isolable from the social fabric, and notions of property may not be stated as such but instead may be framed in negative terms: for example, the taboo system among Polynesian peoples.

== Property in philosophy ==
In [[medieval]] and [[Renaissance]] [[Europe]] the term "property" essentially referred to land. After much rethinking, land has come to be regarded as only a special case of the property genus. This rethinking was inspired by at least three broad features of early modern Europe: the surge of commerce, the breakdown of efforts to prohibit [[interest]] (then called "[[usury]]"), and the development of centralized national [[monarchy|monarchies]].

=== Ancient philosophy ===
[[Urukagina]], the king of the [[Sumer]]ian city-state [[Lagash]], established the first laws that forbade compelling the sale of property.<ref>[[Samuel Noah Kramer]]. "From the Tablets of Sumer: Twenty-Five Firsts in Man's Recorded History." Indian Hills: The Falcon's Wing Press, 1956.</ref>

The Bible in [[Leviticus]] 19:11 and 19:13 states that the [[Israelites]] are not to steal.<ref>{{bibleverse|Leviticus|19:11-13|HE}}</ref>

[[Aristotle]], in ''Politics,'' advocates "private property".<ref>{{Cite web|url=https://www.nytimes.com/books/first/p/pipes-property.html|title=Property and Freedom|website=www.nytimes.com|access-date=2018-01-10}}</ref> He argues that self-interest leads to neglect of the commons. "[T]hat which is common to the greatest number has the least care bestowed upon it. Everyone thinks chiefly of his own, hardly at all of the common interest, and only when he is himself concerned as an individual."<ref>This bears some similarities to the over-use argument of Garrett Hardin's "[[Tragedy of the Commons]]."</ref>

In addition, he says that when property is common, there are natural problems that arise due to differences in labor: "If they do not share equally enjoyments and toils, those who labor much and get little will necessarily complain of those who labor little and receive or consume much. But indeed, there is always a difficulty in men living together and having all human relations in common, but especially in their having common property." ([http://www.cavehill.uwi.edu/bnccde/PH19C/tutorial10.html ''Politics, 1261b34''])

[[Cicero]] held that there is no private property under [[natural law]] but only under [[human law]].<ref>{{cite book |last1=Carlyle |first1=A.J. |title=Property: Its Duties and Rights |date=1913 |publisher=Macmillan |location=London |page=121 |url=https://archive.org/stream/propertyitsdutie00gorerich#page/122/mode/1up |access-date=4 April 2015}}  citing Cicero, [[De officiis]], i. 7, "Sunt autem privata nulla natura".</ref>  [[Seneca the Younger|Seneca]] viewed property as only becoming necessary when men become avaricious.<ref>{{cite book |last1=Carlyle |first1=A.J. |title=Property: Its Duties and Rights |date=1913 |publisher=Macmillan |location=London |page=122 |url=https://archive.org/stream/propertyitsdutie00gorerich#page/122/mode/1up |access-date=4 April 2015}} citing Seneca, Epistles, xiv, 2.</ref>  [[St. Ambrose]] later adopted this view and [[St. Augustine]] even derided heretics for complaining the Emperor could not confiscate property they had labored for.<ref>{{cite book |last1=Carlyle |first1=A.J. |title=Property: Its Duties and Rights |date=1913 |publisher=Macmillan |location=London |page=125 |url=https://archive.org/stream/propertyitsdutie00gorerich#page/125/mode/1up |access-date=4 April 2015}}</ref>

=== Medieval philosophy ===

==== Thomas Aquinas (13th century) ====
The canon law ''[[Decretum Gratiani]]'' maintained that mere human law creates property, repeating the phrases used by St. Augustine.<ref>{{cite book |last1=Carlyle |first1=A.J. |title=Property: Its Duties and Rights |date=1913 |publisher=Macmillan |location=London |page=127 |url=https://archive.org/stream/propertyitsdutie00gorerich#page/127/mode/1up |access-date=4 April 2015}}  citing Decretum, D. viii.

===Modern philosophy===

==== Thomas Hobbes (17th century) ====
The principal writings of [[Thomas Hobbes]] appeared between 1640 and 1651—during and immediately following [[First English Civil War|the war between forces]] loyal to King [[Charles I of England|Charles I]] and those loyal to [[Parliament]]. In his own words, Hobbes' reflection began with the idea of "giving to every man his own," a phrase he drew from the writings of [[Cicero]]. But he wondered: How can anybody call anything his own?

==== James Harrington (17th century) ====

A contemporary of Hobbes, [[James Harrington (author)|James Harrington]], reacted to the same tumult differently: he considered property natural but not inevitable. The author of "[[Oceana (book)|Oceana]]," he may have been the first political theorist to postulate that political power is a consequence, not the cause, of the distribution of property. He said that the worst possible situation is when the commoners have half a nation's property, with the crown and nobility holding the other half—a circumstance fraught with instability and violence. He suggested a much better situation (a stable republic) would exist once the commoners own most property.

In later years, the ranks of Harrington's admirers included American revolutionary and founder [[John Adams]].

==== Robert Filmer (17th century) ====

Another member of the Hobbes/Harrington generation, Sir [[Robert Filmer]], reached conclusions much like Hobbes', but through [[Biblical]] [[exegesis]]. Filmer said that the institution of kingship is analogous to that of fatherhood, that subjects are still, children, whether obedient or unruly and that property rights are akin to the household goods that a father may dole out among his children—his to take back and dispose of according to his pleasure.

==== John Locke (17th century) ====

In the following generation, [[John Locke]] sought to answer Filmer, creating a rationale for a balanced [[constitution]] in which the monarch had a part to play, but not an overwhelming part. Since Filmer's views essentially require that the [[House of Stuart|Stuart]] family be uniquely descended from the [[patriarchs]] of the [[Bible]], and even in the late 17th century, that was a difficult view to uphold, Locke attacked Filmer's views in his [[Two Treatises of Government#First Treatise|First Treatise on Government]], freeing him to set out his own views in the [[Second Treatise on Civil Government]]. Therein, Locke imagined a pre-social world each of the unhappy residents which are willing to create a [[social contract]] because otherwise, "the enjoyment of the property he has in this state is very unsafe, very insecure," and therefore, the "great and chief end, therefore, of men's uniting into commonwealths, and putting themselves under government, is the preservation of their property."<ref>John Locke, "The Second Treatise of Civil Government" (1690), Chap. IX, §§&nbsp;123–124.</ref> They would, he allowed, create a [[monarchy]], but its task would be to execute the will of an elected legislature. "To this end" (to achieve the previously specified goal), he wrote, "it is that men give up all their natural power to the society they enter into, and the community put the [[Legislative power]] into such hands as they think fit, with this trust, that they shall be governed by declared laws, or else their peace, quiet, and property will still be at the same uncertainty as it was in the [[state of nature]]."<ref>John Locke, "The Second Treatise of Civil Government" (1690), Chap. XI, §&nbsp;136.</ref>

Even when it keeps to proper legislative form, Locke held that there are limits to what a government established by such a contract might rightly do.

<blockquote> "It cannot be supposed that [the hypothetical contractors] they should intend, had they a power so to do, to give anyone or more an absolute arbitrary power over their persons and estates, and put a force into the magistrate's hand to execute his unlimited will arbitrarily upon them; this were to put themselves into a worse condition than the State of nature, wherein they had a liberty to defend their right against the injuries of others, and were upon equal terms of force to maintain it, whether invaded by a single man or many in combination. Whereas by supposing they have given themselves up to the absolute arbitrary power and will of a legislator, they have disarmed themselves, and armed him to make a prey of them when he pleases..."<ref>John Locke, "The Second Treatise of Civil Government" (1690), Chap. XI, §&nbsp;137.</ref></blockquote>

Both "persons" and "estates" are to be protected from the arbitrary power of any magistrate, including legislative power and will." In Lockean terms, depredations against an estate are just as plausible a justification for resistance and revolution as are those against persons. In neither case are subjects required to allow themselves to become prey.

To explain the ownership of property, Locke advanced a [[labor theory of property]].

==== David Hume (18th century) ====

In contrast to the figures discussed in this section thus far [[David Hume]] lived a relatively quiet life that had settled down to a relatively stable social and political structure. He lived the life of a solitary writer until 1763 when, at 52 years of age, he went off to [[Paris]] to work at the British embassy.

In contrast, one might think to his polemical works on [[religion]] and his [[empiricism]]-driven [[philosophical skepticism|skeptical]] [[epistemology]], Hume's views on law and property were quite conservative.

He did not believe in hypothetical contracts or the love of humanity in general and sought to ground politics upon actual human beings as one knows them. "In general," he wrote, "it may be affirmed that there is no such passion in the human mind, as the love of mankind, merely as such, independent of personal qualities, or services, or of relation to ourselves." Existing customs should not lightly be disregarded because they have come to be what they are due to human nature. With this endorsement of custom comes an endorsement of existing governments because he conceived of the two as complementary: "A regard for [[liberty]], though a laudable passion, ought commonly to be subordinate to a reverence for established [[government]]."

Therefore, Hume's view was that there are property rights because of and to the extent that the existing law, supported by social customs, secure them.<ref>This view is reflected in the opinion of the [[United States Supreme Court]] in "[[United States v. Willow River Power Co.]]".</ref> He offered some practical home-spun advice on the general subject, though, as when he referred to [[avarice]] as "the spur of [[Private industry|industry]]," and expressed concern about excessive levels of taxation, which "destroy industry, by engendering despair."

====Adam Smith====
{{blockquote| "Civil government, so far as it is instituted for the security of property, is, in reality, instituted for the defense of the rich against the poor, or of those who have property against those who have none at all." | [[Adam Smith]], ''[[The Wealth of Nations]]'', 1776<ref>''[[An Inquiry Into the Nature and Causes of the Wealth of Nations]]'', by [[Adam Smith]], Cooke & Hale, 1818, p. 167</ref>}}

"The property that every man has in his labour is the original foundation of all other property, so it is the most sacred and inviolable. The inheritance of a poor man lies in the strength and dexterity of his hands, and to hinder him from employing this strength and dexterity in what manner he thinks proper without injury to his neighbor, is a plain violation of this most sacred property. It is a manifest encroachment upon the just liberty of the workman and those who might be disposed to employ him. It hinders the one from working at what he thinks proper, so it hinders the others from employing whom they think proper. To judge whether he is fit to be employed may surely be trusted to the discretion of the employers whose interest it so much concerns. The affected anxiety of the law-giver lest they should employ an improper person is as impertinent as it is oppressive."
— (Source: [[Adam Smith]], ''[[The Wealth of Nations]]'', 1776, Book I, Chapter X, Part II.)

By the mid 19th century, the industrial revolution had transformed England and the United States and had begun in France. As a result, the conventional conception of what constitutes property expanded beyond land to encompass scarce goods. In France, the revolution of the 1790s had led to large-scale confiscation of land formerly owned by the church and king. The restoration of the monarchy led to claims by those dispossessed to have their former lands returned.

====Karl Marx====

Section VIII, "[[Primitive accumulation of capital|Primitive Accumulation]]" of Capital involves a critique of Liberal Theories of property rights. Marx notes that under Feudal Law, peasants were legally entitled to their land as the aristocracy was to its manors. Marx cites several historical events in which large numbers of the peasantry were removed from their lands, then seized by the nobility. This seized land was then used for commercial ventures (sheep herding). Marx sees this "Primitive Accumulation" as integral to the creation of English Capitalism. This event created a sizeable un-landed class that had to work for wages to survive. Marx asserts that liberal theories of property are "idyllic" fairy tales that hide a violent historical process.

==== Charles Comte: legitimate origin of property ====

[[Charles Comte]], in "Traité de la propriété" (1834), attempted to justify the legitimacy of private property in response to the [[Bourbon Restoration in France|Bourbon Restoration]]. According to David Hart, Comte had three main points: "firstly, that interference by the state over the centuries in property ownership has had dire consequences for justice as well as for economic productivity; secondly, that property is legitimate when it emerges in such a way as not to harm anyone; and thirdly, that historically some, but by no means all, property which has evolved has done so legitimately, with the implication that the present distribution of property is a complex mixture of legitimately and illegitimately held titles."<ref>[http://homepage.mac.com/dmhart/ComteDunoyer/Ch6.html#RTFToC4 ''The Radical Liberalism of Charles Comte and Charles Dunoyer''] {{webarchive|url=https://web.archive.org/web/20060130070015/http://homepage.mac.com/dmhart/ComteDunoyer/Ch6.html |date=2006-01-30 }}</ref>

Comte, as Proudhon later did, rejected [[Roman law|Roman legal tradition]] with its toleration of slavery. Instead, he posited a communal "national" property consisting of non-scarce goods, such as land in ancient hunter-gatherer societies. Since agriculture was so much more efficient than hunting and gathering, private property appropriated by someone for farming left remaining hunter-gatherers with more land per person and hence did not harm them. Thus this type of land appropriation did not violate the [[Lockean proviso]] – there was "still enough, and as good left." Later theorists would use Comte's analysis in response to the socialist critique of property.

==== Pierre-Joseph Proudhon: property is theft ====
{{Main|Property is theft!}}

In his 1840 treatise ''What is Property?'', [[Pierre Proudhon]] answers with "[[Property is theft!]]". In natural resources, he sees two types of property, ''de jure'' property (legal title) and ''de facto'' property (physical possession), and argues that the former is illegitimate. Proudhon's conclusion is that "property, to be just and possible, must necessarily have equality for its condition."

His analysis of the product of labor upon natural resources as property ([[usufruct]]) is more nuanced. He asserts that land itself cannot be property, yet it should be held by individual possessors as stewards of humanity, with the product of labor being the producer's property. Proudhon reasoned that any wealth gained without labor was stolen from those who labored to create that wealth. Even a voluntary contract to surrender the product of work to an employer was theft, according to Proudhon, since the controller of natural resources had no moral right to charge others for the use of that which he did not labor to create did not own.

Proudhon's theory of property greatly influenced the budding socialist movement, inspiring anarchist theorists such as [[Mikhail Bakunin]] who modified Proudhon's ideas, as well as antagonizing theorists like [[Karl Marx]].

==== Frédéric Bastiat: property is value ====

[[Frédéric Bastiat]] 's main treatise on property can be found in chapter 8 of his book "Economic Harmonies" (1850).<ref>{{cite book |title=Bastiat: Economic Harmonies }}</ref> In a radical departure from traditional property theory, he defines property, not as a physical object, but rather as a relationship between people concerning a thing. Thus, saying one owns a glass of water is merely verbal shorthand for "I may justly gift or trade this water to another person." In essence, what one owns is not the object but the object's value. By "value," Bastiat means "market value"; he emphasizes this is quite different from utility. "In our relations with one another, we are not owners of the utility of things, but their value, and value is the appraisal made of reciprocal services."

Bastiat theorized that, as a result of technological progress and the division of labor, the stock of communal wealth increases over time; that the hours of work an unskilled laborer expends to buy e.g., 100 liters of wheat, decreases over time, thus amounting to "gratis" satisfaction.<ref>{{cite web |url=http://oll.libertyfund.org/?option=com_staticxt&staticfile=show.php?title=79&chapter=35530&layout=html&Itemid=27 |title=Economic Harmonies (Boyers trans.) – Online Library of Liberty |access-date=14 May 2015}}</ref> Thus, private property continually destroys itself, becoming transformed into communal wealth. The increasing proportion of communal wealth to private property results in a tendency toward equality of humanity. "Since the human race began in greatest poverty, that is, when there were the most obstacles to overcome, all that has been achieved from one era to the next is due to the spirit of property."

This transformation of private property into the communal domain, Bastiat points out, does not imply that personal property will ever totally disappear. On the contrary, this is because man, as he progresses, continually invents new and more sophisticated needs and desires.

==== Andrew J. Galambos: a precise definition of property ====

[[Andrew Joseph Galambos|Andrew J. Galambos]] (1924–1997) was an astrophysicist and philosopher who innovated a social structure that sought to maximize human peace and freedom. Galambos' concept of property was essential to his philosophy. He defined property as a man's life and all non-procreative derivatives of his life. (Because the English language is deficient in omitting the feminine from "man" when referring to humankind, it is implicit and obligatory that the feminine is included in the term "man.")

Galambos taught that property is essential to a non-coercive social structure. He defined freedom as follows: "Freedom is the societal condition that exists when every individual has full (100%) control over his property."<ref>Galambos, Andrew (1999). Sic Itur Ad Astra. San Diego, California: The Universal Scientific Publications Company, Inc. pp. 868–869. {{ISBN|0-88078-004-5}}.</ref> Galambos defines property as having the following elements:
* Primordial property, which is an individual's life
* Primary property, which includes ideas, thoughts, and actions
* Secondary property includes all tangible and intangible possessions that are derivatives of the individual's primary property.

Property includes all non-procreative derivatives of an individual's life; this means children are not the property of their parents.<ref>Galambos, Andrew (1999). Sic Itur Ad Astra. San Diego, California: The Universal Scientific Publications Company, Inc. p. 23. {{ISBN|0-88078-004-5}}.</ref> and "primary property" (a person's own ideas).<ref>Galambos, Andrew (1999). Sic Itur Ad Astra. San Diego, California: The Universal Scientific Publications Company, Inc. pp. 39, 52, 84, 92–93, 153, 201, 326. {{ISBN|0-88078-004-5}}.</ref>

Galambos repeatedly emphasized that actual government exists to protect property and that the State attacks property.
For example, the State requires payment for its services in the form of taxes whether or not people desire such services. Since an individual's money is his property, the confiscation of money in the form of taxes is an attack on property. Military conscription is likewise an attack on a person's primordial property.

===Contemporary views===

Contemporary political thinkers who believe that natural persons enjoy rights to own property and enter into contracts espouse two views about John Locke. On the one hand, some admire Locke, such as [[William Harold Hutt|William H. Hutt]] (1956), who praised Locke for laying down the "quintessence of individualism." On the other hand, those such as [[Richard Pipes]] regard Locke's arguments as weak and think that undue reliance thereon has weakened the cause of individualism in recent times. Pipes has written that Locke's work "marked a regression because it rested on the concept of [[Natural Law]]" rather than upon Harrington's sociological framework.

[[Hernando de Soto Polar|Hernando de Soto]] has argued that an essential characteristic of the capitalist market economy is the functioning state protection of property rights in a formal [[property system]] which records ownership and transactions. These property rights and the whole legal system of property make possible:
* Greater independence for individuals from local community arrangements to protect their assets
* Clear, provable, and protectable ownership
* The standardization and integration of property rules and property information in a country as a whole
* Increased trust arising from a greater certainty of punishment for cheating in economic transactions
* More formal and complex written statements of ownership that permit the more straightforward assumption of shared risk and ownership in companies, and insurance against the risk
* Greater availability of loans for new projects since more things can serve as collateral for the loans
* Easier access to and more reliable information regarding such things as credit history and the worth of assets
* Increased [[fungibility]], standardization, and transferability of statements documenting the ownership of property, which paves the way for structures such as national markets for companies and the easy transportation of property through complex networks of individuals and other entities
* Greater protection of biodiversity due to minimizing of [[shifting agriculture]] practices

According to de Soto, all of the above enhance [[economic growth]].<ref>{{cite web |url=http://www.imf.org/external/pubs/ft/fandd/2001/03/desoto.htm |title=Finance & Development, March 2001 – The Mystery of Capital |work=Finance, and Development – F&D |access-date=14 May 2015}}</ref> Academics have criticized the capitalist frame through which property is viewed pointing to the fact that commodifying property or land by assigning it monetary value takes away from the traditional cultural heritage, particularly from first nation inhabitants.<ref name= "ReferenceA">Kristen A.
