Quite different, on the other hand, are matters conditioned when the inquirer has before him the laws of all the peoples of the earth from the lowest to the highest. Here he has in his possession a picture of the jural consciousness of the mind of humanity, which is no longer subject to alteration, but which, to the extent that the development of human jural life has advanced, is complete. For the execution of its task ethnological jurisprudence first requires a collection of the laws of all the peoples of the earth. Each one of these laws is of equal value to ethnological jurisprudence in so far as the jural consciousness of humanity has found expression in it in any form. Especially deserving of consideration are the laws of the so-called savage peoples that have been so much neglected and contemned hitherto; since they bring to light the jural consciousness of humanity in its germinal stages, and since higher formations are invariably best understood when we know their first beginnings. The solidest basis for ethnological jurisprudence would be furnished by a monographic treatment of the law of every single tribe and people of the earth. By such monographic treatments the entire social organisation of a given tribe or people would be exhibited in all its complicated reciprocal relations, and we should be able to follow the law in all the thousands of minute ramifications that connect it with the remaining provinces of national life. But such a monographic treatment of the law of all the nations of the earth is accompanied with great difficulties, and this part of the task of the science of law has as yet been undertaken only to a limited extent. The condition of affairs is best in this respect where the nations themselves have collected and compiled their legal customs in books of laws. But such collections are found only among peoples that deserve to some extent the appellation of civilised peoples. Among the great majority of peoples the law is simply practised and handed down by oral tradition, so that here the legal customs must be collected by members of foreign civilised nations,—a very difficult labor and one that can be accomplished only by persons who take up their abode permanently among the races in question and become thoroughly familiar with their language and habits of life. Collections of this character we possess unfortunately only to a very limited extent, and our knowledge accordingly of the law of uncivilised peoples is still very meagre. Even the books of law possessed by the various peoples have not all been made available to juristic science. In part they have not yet been printed, and in part they have not yet been translated into a generally understood language. Considerable time will yet be required before the existing material has been made wholly accessible.
