A great movement, called Zionism, arose among them. Its aim was to assert the national character of Judaism, and the movement was strongly represented in Vienna. To outward appearances it seemed as if only one group of Jews championed this movement, while the great majority disapproved of it, or even repudiated it. But an investigation of the situation showed that those outward appearances were purposely misleading. These outward appearances emerged from a mist of theories which had been produced for reasons of expediency, if not for purposes of downright deception. For that part of Jewry which was styled Liberal did not disown the Zionists as if they were not members of their race but rather as brother Jews who publicly professed their faith in an unpractical way, so as to create a danger for Jewry itself. Thus there was no real rift in their internal solidarity.
