Frequently, however, the individual Socialist forgets this materialistic theory, and falls back upon his common sense, and his innate conceptions of right and wrong, of free will and responsibility. Instead of regarding the existing land system as a mere product of blind economic forces, he often denounces it as morally wrong and unjust. His contentions may be reduced to two propositions: The proprietor who takes rent from a cultivator robs the producer of a part of his product; and no one has a right to take for his exclusive use that which is the natural heritage and means of support for all the people. Referring to the receipt of 35,000,000 pounds a year in rent by 8,000 British landlords, Hyndman and Morris exclaim: "Yet in the face of all this a certain school still contend that there is no class robbery."[9] Since the claim that the labourer has a right to the full product of his labour applies to capital as well as to land, it can be more conveniently considered when we come to treat of the income of the capitalist. With regard to the second contention, the following statement by Robert Blatchford may be taken as fairly representative of Socialist thought: "The earth belongs to the people.... So that he who possesses land possesses that to which he has no right, and he who invests his savings in land becomes the purchaser of stolen property."[10] Inasmuch as this argument is substantially the same as one of the fundamental contentions in the system of Henry George, it will be discussed in connection with the latter, in the pages immediately following. _Henry George's Attack on the Title of First Occupancy_ Every concrete right, whether to land or to artificial goods, is based upon some contingent fact or ground, called a title. By reason of some title a man is justified in appropriating a particular farm, house, or hat. When he becomes the proprietor of a thing that has hitherto been ownerless, his title is said to be original; when he acquires an article from some previous owner, his title is said to be derived. As an endless series of proprietors is impossible, every derived title must be traceable ultimately to some original title. Among the derived titles the most important are contract, inheritance, and prescription. The original title is either first occupancy or labour. The prevailing view among the defenders of private landownership has always been that the original title is not labour but first occupancy. If this title be not valid every derived title is worthless, and no man has a true right to the land that he calls his own. Henry George's attack upon the title of first occupancy is an important link in his argument against private property in land.
