One effect of _Daniel Deronda_ was to make known to a wide circle of readers the vitality of Judaism as a system which still holds sway over the mental as well as the external life of men. During the few years which have passed since the publication of that great fiction, the interest in modern Judaism has continued to grow. It is but a short time since the Western world was startled by the outbreak of an ancient feeling against the Jews, which had been supposed to be long dead, at least in some of the quarters where it was displayed. The popular literature of the day also seems to indicate that the life of existing Jewish communities is attracting a large share of attention in the reading world. The charming pictures which Emil Franzos has drawn of Jewish life in the villages of Eastern Galicia, are not only popular in Germany, but some have been reproduced in a cheap form in New York to meet the demand of German Americans, and some have also been translated into English. The interest of English readers in the same subject is further shown by the recent translation of Kompert's _Scenes from the Ghetto_, as well as by Mr. Cumberland's still more recent and powerful romance of _The Rabbi's Spell_. Among students of philosophical literature a fresh interest has been awakened in the history of Jewish thought by the revival of the question in reference to the sources of Spinoza's philosophy. The affinities of this system with the familiar tendencies of Cartesian speculation have led the historians of philosophy generally to represent the former as simply an inevitable development of the latter, while the affinities of Spinozism with the unfamiliar speculations of earlier Jewish thinkers have been almost entirely ignored. In these circumstances a special interest may be felt in the life of one of the most remarkable Jews of modern times--a life which forms one of the most extraordinary biographies in the history of literature.
