This form of individual ownership will then always continue to exist, since it is necessary and perfectly consistent with social ownership of the land, mines, factories, houses, machines, tools and instruments of labor, and means of transportation. The collective ownership of libraries--which we see in operation under our eyes--does it deprive individuals of the personal use of rare and expensive books which they would be unable to procure in any other way, and does it not largely increase the utility that can be derived from these books, when compared to the services that these books could render if they were shut up in the private library of a useless book-collector? In the same way, the collective ownership of the land and the means of production, by securing to everyone the use of the machines, tools and land, will only increase their utility a hundred-fold. And let no one say that, when men shall no longer have the exclusive and transferable (by inheritance, etc.) _ownership_ of wealth, they will no longer be impelled to labor because they will no longer be constrained to work by personal or family self-interest.[57] We see, for example, that, even in our present individualist world, those survivals of collective property in land--to which Laveleye has so strikingly called the attention of sociologists--continue to be cultivated and yield a return which is not lower than that yielded by lands held in private ownership, although these communist or collectivist farmers have only the right of use and enjoyment, and not the absolute title.[58] If some of these survivals of collective ownership are disappearing, or if their administration is bad, this can not be an argument against socialism, since it is easy to understand that, in the present economic organization based on absolute individualism, these organisms do not have an environment which furnishes them the conditions of a possible existence. It is as though one were to wish a fish to live out of water, or a mammal in an atmosphere containing no oxygen. These are the same considerations which condemn to a certain death all those famous experiments--the socialist, communist or anarchist colonies which it has been attempted to establish in various places as "experimental trials of socialism." It seems not to have been understood that such experiments could only result in inevitable abortions, obliged as they are to develop in an individualist economic and moral environment which can not furnish them the conditions essential for their physiological development, conditions which they will, on the contrary, have when the whole social organization shall be guided by the collectivist principle, that is to say, when society shall be _socialized_.[59]
