The significance of Jewish history is twofold. It is at once national and universal. At present the fulcrum of Jewish national being lies in the historical consciousness. In the days of antiquity, the Jews were welded into a single united nation by the triple agencies of state, race, and religion, the complete array of material and spiritual forces directed to one point. Later, in the period of homelessness and dispersion, it was chiefly religious consciousness that cemented Jewry into a whole, and replaced the severed political bond as well as the dulled racial instinct, which is bound to go on losing in keenness in proportion to the degree of removal from primitive conditions and native soil. In our days, when the liberal movements leavening the whole of mankind, if they have not completely shattered the religious consciousness, have at least, in an important section of Jewry, effected a change in its form; when abrupt differences of opinion with regard to questions of faith and cult are asserting their presence; and traditional Judaism developed in historical sequence is proving powerless to hold together the diverse factors of the national organism,--in these days the keystone of national unity seems to be the historical consciousness. Composed alike of physical, intellectual, and moral elements, of habits and views, of emotions and impressions nursed into being and perfection by the hereditary instinct active for thousands of years, this historical consciousness is a remarkably puzzling and complex psychic phenomenon. By our common memory of a great, stirring past and heroic deeds on the battle-fields of the spirit, by the exalted historical mission allotted to us, by our thorn-strewn pilgrim's path, our martyrdom assumed for the sake of our principles, by such moral ties, we Jews, whether consciously or unconsciously, are bound fast to one another. As Renan well says: "Common sorrow unites men more closely than common joy." A long chain of historical traditions is cast about us all like a strong ring. Our wonderful, unparalleled past attracts us with magnetic power. In the course of centuries, as generation followed generation, similarity of historical fortunes produced a mass of similar impressions which have crystallized, and have thrown off the deposit that may be called "the Jewish national soul." This is the soil in which, deep down, lies imbedded, as an unconscious element, the Jewish national _feeling_, and as a conscious element, the Jewish national _idea_.
