“The first cause of property,” says M. Matthieu Walkoff,[4] “is the impossibility of matter being moved in more than one direction at one time, or, to state it otherwise, of its being subject at one time to more than one will.” “If matter,” says this eminent economist, “were gifted with ubiquity, like ideas, knowledge, or truth, which several may use simultaneously, and each in his own way, property would never have been constituted; and it is even difficult to imagine how any idea on this phenomenon could have arisen in men’s minds.” “In fact,” he adds, “to preserve property in an idea would have required that it should never have been expressed nor practised, to hinder it, being divulged, which would have been equivalent to its non-existence.” We do not go so far as M. Walkoff; we do not affirm that the impossibility of matter being subject at one time to more than one will is the _first cause_ of property; but we say it is the distinctive character of property, and, like him, we cannot see a subject, for property is a shape, plan, or system, which, to see once, as in a spade, the wheel, the corkscrew, is to possess an indelible idea. Besides, the author whom we have quoted expresses so clearly our opinion on this subject, that we must further borrow from him the following quotation, which will not be uncalled for at a time when property itself is threatened. It is of importance that the lawful bounds should be carefully marked:— “Economists have too much neglected the first cause of the perpetual subjection of matter to exclusive property. They made property to be derived only from a man’s original possession; from himself and his acts; that which leads to possession of the result of his activity. But this reasoning only establishes the indisputable right of the appropriation of that which he appropriates or produces; it does not explain why exclusive property in material things is permanent, and does not show how the very nature of things renders this possession inevitable. It is to the incomplete understanding of the causes of property that is probably attributable the contradictions of those economists who, while professing the doctrine of free labour, are still in favour of the establishment of artificial barriers against the free use by every one of ideas, skill, progress, and other products of the mind, conceived and suggested, or realised, by any one.” Let us remark here that in fact the manufacturing community, more liberal in practice than the economists in theory, are eager freely to submit to inspection at exhibitions the processes in use at their different factories.
