While at the University, he heard lectures on a wide variety of subjects--on history, philosophy, Oriental languages, even physics--but it does not appear that any left deep traces upon his mind. Even Professor Bernstein, an Orientalist of considerable reputation, who drew him into the circle of his close associates, did not understand how to kindle his pupil’s zeal, usually so impetuous, for the thorough study of Syriac and Arabic. Apparently Graetz had relinquished the ambition to gain mastery of them. The only one to have success was Professor Braniss, a philosopher in high esteem in his day, with whom also Graetz cultivated intimate relations. He at all events must have been instrumental in acquainting him with the Hegelian system of philosophy, and in imbuing him with the recognition, that even in the world of liberty, that is, man’s world of mental endeavor, phases of development succeed each other in conformity with absolute laws, chiefly of an ideal, non-mechanical nature; that therefore the spiritual powers that produce the history of mankind by the realization of ever higher ideas not only follow their indwelling laws, but at the same time submit unconditionally to the law of cause and effect; and that the paradox of opposites, the principle of thesis, antithesis, and synthesis, is particularly helpful in the consideration of historical phenomena. Though Graetz was immersed in his studies, he did not fail to give close attention to the occurrences in the Breslau Jewish community. The events happening there in those days were not merely of local interest. They cast their light and their shadow far beyond the Silesian frontier, and were the cause of intense excitement in all Jewish circles of Germany. In Breslau the orthodox and the reform views of Judaism for the first time rushed at each other with full force in the struggle for supremacy. Storm and conflict raged violently between the old and the new. Blind to the conditions of the time, orthodoxy stubbornly opposed a _non possumus_ to every offer looking to an adjustment of difficulties. The representatives of the two parties, the orthodox Solomon Tiktin on the one side and the progressive Abraham Geiger on the other, sought to get the better of each other with remorseless acrimony. Geiger won the upper hand, and even the disruption of the Breslau congregation caused by Tiktin’s defeat did not derogate from the reform champion’s victory.
