The Semitic family is divided by M. Renan into two great branches, differing from each other in the form of their monotheistic belief, yet both, according to their historian, imbued from the beginning with the instinctive faith in one God: 1. The nomad branch, consisting of Arabs, Hebrews, and the neighbouring tribes of Palestine, commonly called the descendants of Terah; and 2. The political branch, including the nations of Phenicia, of Syria, Mesopotamia, and Yemen. Can it be said that all these nations, comprising the worshippers of Elohim, Jehovah, Sabaoth, Moloch, Nisroch, Rimmon, Nebo, Dagon, Ashtaroth, Baal or Bel, Baal-peor, Baal-zebub, Chemosh, Milcom, Adrammelech, Annamelech, Nibhaz and Tartak, Ashima, Nergal, Succoth-benoth, the Sun, Moon, planets, and all the host of heaven, were endowed with a monotheistic instinct? M. Renan admits that monotheism has always had its principal bulwark in the nomadic branch, but he maintains that it has by no means been so unknown among the members of the political branch as is commonly supposed. But where are the criteria by which, in the same manner as their dialects, the religions of the Semitic races could be distinguished from the religions of the Aryan and Turanian races? We can recognise any Semitic dialect by the triliteral character of its roots. Is it possible to discover similar radical elements in all the forms of faith, primary or secondary, primitive or derivative, of the Semitic tribes? M. Renan thinks that it is. He imagines that he hears the key-note of a pure monotheism through all the wild shoutings of the priests of Baal and other Semitic idols, and he denies the presence of that key-note in any of the religious systems of the Aryan nations, whether Greeks or Romans, Germans or Celts, Hindus or Persians. Such an assertion could not but rouse considerable opposition, and so strong seems to have been the remonstrances addressed to M. Renan by several of his colleagues in the French Institute that, without awaiting the publication of the second volume of his great work, he has thought it right to publish part of it as a separate pamphlet. In his 'Nouvelles Considérations sur le Caractère Général des Peuples Sémitiques, et en particulier sur leur Tendance au Monothéisme,' he endeavours to silence the objections raised against the leading idea of his history of the Semitic race. It is an essay which exhibits not only the comprehensive knowledge of the scholar, but the warmth and alacrity of the advocate. With M. Renan the monotheistic character of the descendants of Shem is not only a scientific tenet, but a moral conviction. He wishes that his whole work should stand or fall with this thesis, and it becomes, therefore, all the more the duty of the critic, to inquire whether the arguments which he brings forward in support of his favourite idea are valid or not.
