See International Language and Science, 1910, by Couturat, Jespersen, Lorenz, Ostwald, Pfaundler, and Donnan, five professors living in five different countries.

The progress of the movement is recorded in its official journal, Progreso, edited by Couturat, and in De Beaufront's journal, La Langue Auxiliaire.

In the narrow sense Socialism is identical with the definite economic doctrine of the Collectivistic organization of the productive and distributive work of society. It also possesses, as Bosanquet remarks (in an essay on "Individualism and Socialism," in The Civilization of Christendom), "a deeper meaning as a name for a human tendency that is operative throughout history." Every Collectivist is a Socialist, but not every Socialist would admit that he is a Collectivist. "Moral Socialism," however, though not identical with "Economic Socialism," tends to involve it.

The term "Individualism," like the term "Socialism," is used in varying senses, and is not, therefore, satisfactory to everyone. Thus E.F.B. Fell (The Foundations of Liberty, 1908), regarding "Individualism," as a merely negative term, prefers the term "Personalism," to denote a more positive ideal. There is, however, by no means as any necessity to consider "Individualism," a more negative term than "Socialism."
