The attention, energy and time which Herzl devoted to literature, at fifteen, his absorption in himself, his activity in the school literary society meant of course so much less given to his school work. He found no time at all for science; Jewish questions likewise disappeared from his interests; he was completely absorbed by German literary culture. This is all the more astonishing when we reflect that anti-Semitism continued to increase steadily. As a grown man Herzl could recall that one of his teachers, in defining the word "heathen," had said, "such as idolators, Mohammedans and Jews." Whether it was this incident,--as the memory of the grown man always insisted--which enraged him beyond endurance, or the increasingly bad school reports, or both circumstances together, the fact remains that on February 4, 1875 Herzl left the Technical School. At sixteen to eighteen in High School, he struggled to define the basic principles of various literary art forms in order that he might see more clearly what he himself wanted to say. He took an active and eager part in the work of the "German Self-Education Society" created by the students of his school. The Jewish world, whose inferior position always wounded his pride, and whose obstinate separatism seemed to him utterly meaningless, drifted further and further out of his mind. At eighteen, after the sudden death of his only sister, the family moved to Vienna where Herzl entered the University as a law student. Herzl, who accounted himself a liberal and an Austrian patriot, plunged eagerly into the activities of a large student Cultural Association, attended its discussions and directed its literary evenings. He had occasion, there, to deride certain Jewish fellow members who, in his view, displayed an excessive eagerness in their loyalty to various movements. This was the extent to which, in these days, he occupied himself with the Jewish question--at least externally. He concerned himself little or not at all with the official Jewish world which was seeking to submerge itself in the surrounding world. He seldom visited the synagogue. He was an omnivorous reader. His extraordinary knowledge of books was evident in his conversation, for he liked to adorn his speech with quotations, which came readily to his memory. Herzl read Eugen Duehring's book _The Jewish-Problem as a Problem of Race, Morals and Culture_--the first and most important effort to find a "scientific," philosophic, biologic and historical basis for the anti-Semitism which was sweeping through Europe in those days (1881). Duehring saw the Jewish question as a purely racial question, and for him the Jewish race was without any worth whatsoever. Those peoples which, out of a false sentiment of humanity, had permitted the Jews to live among them with equal and sometimes even with superior rights, had to be liberated from the harmful intruder, had to be de-Judaized.
