The physical having of economic goods, which economically considered constitutes the essence of natural ownership, can only be conceived as having originated through Occupation. Since ownership is not a fact independent of the will and action of man, it is impossible to see how it could have begun except with the appropriation of ownerless goods. Once begun ownership continues, as long as its object does not vanish, until either it is given up voluntarily or the object passes from the physical having of the owner against his will.

It is only slowly and with difficulty that the idea of Law triumphs. Only slowly and with difficulty does it rebut the principle of violence. Again and again there are reactions; again and again the history of Law has to start once more from the beginning.

The earliest attempts to reform ownership and property can be accurately described as attempts to achieve the greatest possible equality in the distribution of wealth, whether or not they claimed to be guided by considerations of social utility or social justice. All should possess a certain minimum, none more than a certain maximum. All should possess about the same amount –that was, roughly, the aim. The means to this end were not always the same. Confiscation of all or part of the property was usually proposed, followed by redistribution.

It is an old trick of political innovators to describe that which they seek to realize as Ancient and Natural, as something which has existed from the beginning and which has been lost only through the misfortune of historical development; men, they say, must return to this state of things and revive the Golden Age. Thus natural law explained the rights which it demanded for the individual as inborn, inalienable rights bestowed on him by Nature.

Socialism is the watchword and the catchword of our day. The socialist idea dominates the modern spirit. The masses approve of it, it expresses the thoughts and feelings of all; it has set its seal upon our time. When history comes to tell our story it will write above the chapter ‘The Epoch of Socialism’.

The starting-point of socialist doctrine is the criticism of the bourgeois order of society. We are aware that socialist writers have not been very successful in this respect. We know that they have misconceived the working of the economic mechanism, and that they have not understood the function of the various institutions of the social order which is based on division of labour and on private ownership of the means of production.

There are two ways of treating the problems which Socialism sets to Science.

It is a matter of dispute whether, prior to the middle of the nineteenth century, there existed any clear conception of the socialist idea — by which is understood the socialization of the means of production with its corollary, the centralized control of the whole of production by one social or, more accurately, state organ. The answer depends primarily upon whether we regard the demand for a centralized administration of the means of production throughout the world as an essential feature in a considered socialist plan.
