This little book has made its way. In addition to the present translation into English, there are authorized editions in French, Hungarian and Serbian. I am also informed that there are translations published in Japanese, Russian, Hebrew and Yiddish; but these, of course, are pirated. The book has stood the test of criticism, and has been judged both favorably and unfavorably. It has, unquestionably, revived the discussion on the origin and essence of the State.<br><br>Several prominent ethnologists, particularly Holsti, the present Minister of Foreign Affairs of the Finnish Free State, have attacked the basic principle formulated and demonstrated in this work, but they have failed, because their definition of the State assumed the very matter that required to be proven. They have brought together a large array of facts in proof of the existence of some forms of Government and Leadership, even where no classes obtained, and to the substance of these forms they have given the name of "The State." It is not my intention to controvert these facts. It is self-evident, that in any group of human beings, be it ever so small, there must exist an authority which determines conflicts and, in extraordinary situations, assumes the leadership.
