§ 4. Some theories of private property. Various theories have been framed to explain the origin and to justify the existence of private property. The occupation theory is that property is based upon the priority of claim of one who finds wealth without an owner and appropriates it. This is not an explanation of the property rights that are arising every moment, nor does it give a logical reason for the continuance of ancient property rights. It is a statement applying to a case that has rarely happened, the settlement of an unoccupied territory.

More adequate to explain many cases is the conquest theory, that property is based on force; for nearly all lands to-day are occupied by the descendants of conquering invaders who took the lands and natural resources from the former inhabitants, who in turn had taken them from other occupants many centuries before. The conquest theory applies, for example, to the invasion of the Roman provinces by barbarian tribes who divided the country and developed the feudal system based on land tenure. But it hardly applies to present-day happenings, and at its best it cannot, to modern minds, "justify" present property rights.

The labor theory, meeting some queries where others fail, is that ownership is based on the act of production. It is declared that every man has a right to that to which his brain and his muscles have imparted value. It is apparent that this test leaves without explanation or justification a great number of things that do exist and have existed as property. Usually the basis of the labor theory of property is declared to be each individual's natural right to the results of his own labor, which claim is assumed to be an ultimate, undebatable, axiomatic fact. However, that type of natural-right doctrine, which makes no appeal to experience and results, is now quite discredited in political science.

Another form of natural-rights theory is that property is necessary for the realization of the dignity of human nature, and every individual has the natural right to self realization. This theory is, in a way, based on an appeal to experience as to the effect of property on human character, and it has the virtue of expressing one of the ideals of modern democracy. Although, in common with various other "natural-rights" theories, it must be deemed too absolute and too individualistic, it contains a far-reaching truth, of which due account must be taken in our social philosophy.

The legal theory is that property exists because the law says it shall. This expresses a truth, but is no more than a truism. The law determines the limits of property, but what determines the limits of the law? What practical or social justification is there for passing and continuing such law? The legal theory does not contain a final explanation.

Each of the five theories has its defects, but each points to some fact important and significant, at certain times and places, in the explanation of this widespread institution. They all find some place within a more comprehensive sixth theory, that of social expediency, which will be outlined below. First, however, let us briefly survey some of the historical and legal qualifications of property as it has been and is.

§ 5. Origin vs. justification. The question of the origin is not the same as that of the present justification of the existing system of private property. The institution of private property has evolved under diverse conditions. In early societies individual property rights were not very clearly marked. Every tribe asserted against other tribes, and tried to uphold by war, its claims upon its customary hunting-grounds; but the claims of the individual hunters on land within the tribe did not often come into conflict. Private properly at the outset was in personal possessions, ornaments, weapons, utensils, which were very meager in that primitive society in which it was the custom "to go calling with a club instead of a card-case." Only later came individual property in land. A few years ago it was generally believed that the organization of the old German tribes was politically an almost perfect democracy, and economically a communism in which all had equal claims upon the land. To-day this opinion is very seriously questioned. It seems probable that there was a goodly measure of communism in the control and use of lands (though not in other things), but this was largely confined to an oligarchy of the favored; whereas the masses lived in subjection, cut off from all but a meager share in the common lands. However that may have been, strong forces within historic times have put an end to the common ownership and tillage of land as it existed among the peasants of Europe. That system was shown by experience to be wasteful. Competition tended to bring the economic agents into more efficient hands, and the movement was furthered by many acts of injustice and violence on the part of those in power.

Inquiries into the origin and development of any social institution are interesting and helpful in forming an estimate of its present significance, but the problems of the past are not those of to-day. Whether or not the ancient beginning of property in Europe was in violence and evil has but a remote bearing on the question as to the present working of it. Social conditions and needs have not changed more than have the forms and limits of property itself. Each generation has its own problems to solve, and, ignoring for the most part the evils of the distant past, each generation must test existing institutions by their present results.

§ 6. Limitations of private property. It is well, in discussing private property, to rid the mind at once of the idea that it is an absolute and unchanging thing. Few realize the manifold ways in which property rights are limited. Unmodified private control of property is unknown; the public makes many reservations in its own interest. There is, first, a whole set of limitations to prevent nuisances. An owner in many situations is not free to build a slaughter-house or to start a glue-factory on his land. Property is governed by general public utility, and anything that threatens to become a nuisance or a danger may be excluded. Under the right of eminent domain, the state or the railroad may take the old homestead from the owner who would live and die there. Although pecuniary damages are paid to him, this is a limitation of his property rights. Rights of way on property exist either by contract or by prescription permitting its public use. Most important of all limitations is the right of taxation, by which society takes more or less of private incomes for purposes of which the individual owners may not approve.

The law enforces a multitude of private claims by some persons against others. A variety of rights called easements or servitudes may attach to private property, modifying its exclusive use. Leases for any period are a limitation of the owner's control. Both the holder of the lease and the owner of the property have certain rights before the law. The lender of money secured by mortgage has a legally recognized and enforceable equity in the mortgaged wealth. Property is left in trust for the benefit of persons or of institutions or of the public, and is administered by trustees who are strictly bound to execute the terms of their instructions. Contracts of many sorts are entered into by owners, limiting their control in manifold ways, and the law enforces these contracts. These all form a complex of equitable claims, which together equal in value one undivided property right, which in turn equals the value of the wealth.3 These claims mutually delimit each other (whether they be called equitable claims, or liens, or property rights), and wealth is not multiplied by multiplying the claims, as is unfortunately sometimes assumed to be the case.

§ 7. Limitations of bequest and inheritance. The term bequest implies a will, usually a written will in which the person, in anticipation of death, expresses his wishes as to the disposition of his property. It is said sometimes that bequest is a " logical" result of private property, but the law does not treat it as necessary. The right of bequest, or of gift at death, is limited in various ways in different countries. In countries where hereditary aristocracies exist, primogeniture is in some cases required by law, in others so strongly favored by public opinion that it is practically always followed. Custom limits bequests in England to members of the family, and wills giving outside the family are rare, and are almost always broken in the courts. John Stuart Mill contrasted this with the practice in America, frequent even in his day and still more frequent now, of rich men giving for public purposes. In France the right of bequest outside the family is legally limited; only the share of one child can be willed away by the father, and the rest must be equally divided among the children. "Settlements" and fidei commissa are limited in many countries because of the recognized social evils resulting from the tying up of estates for generations. Throughout the history of England, Parliament has given attention to the question of mortmain, which chiefly concerned the drifting of great estates into the hands of the church or of corporations as the result of bequests by the pious. In England, of late (and to a less extent in this country), the policy of permitting unlimited endowments to charitable institutions has been seriously questioned, and by legislation some of the old endowments have been diverted from their original purposes when these have ceased to be of social utility. Inheritance, in contrast with bequest, usually means succession to the property of one who has died intestate, that is, has made no will. The law of inheritance likewise varies greatly with time and place.
