After having learned German, Krochmal proceeded to acquire a knowledge of Latin and French, and to read the best books written in those languages. To deepen his knowledge of Hebrew, he studied Arabic and Syraic, but we are unable to say how far he succeeded in mastering these languages. With these studies, which appear to have occupied our philosopher for an interval of ten years after his marriage, the first period of his life seems also to end. But the hard work of ten years did not pass over the delicate youth without undermining his health for ever. At the age of twenty‐four, Krochmal fell sick of an illness which compelled him to interrupt his work. He was forced to go to Lemberg to consult the doctors of that town, and he had to remain there for a long time. And now began Krochmal’s career as a teacher. For during his stay at Lemberg there gathered round him a band of young scholars whom Krochmal’s fame had already reached. It is useless to enumerate the names of all these students. Among them figured Isaac Erter, Samson Bloch, A. Bodek, and many others. The most gifted of them was undoubtedly Rapoport, who afterwards became even more famous than his master Krochmal. It is not easy to define accurately the relation that subsisted between these two men. Graetz, in his history, calls Rapoport a disciple of Krochmal. Rapoport himself, in his memoir of Krochmal, describes the latter as a dear friend with whom he was wont to discuss literary topics. Zunz does not mention Rapoport at all in his account of our author. It seems to me that this relation may be most aptly defined by the Talmudic term “Talmid‐Chaber,”(23) “disciple‐ colleague.” Indeed, Krochmal’s whole method of teaching was rather that of a companion than of a professor. He gave no set lectures on particular subjects, but conveyed his instruction rather by means of suggestive conversations with his younger friends. His usual habit was to walk with his pupils in the neighbourhood of the town, and to try to influence their minds each in accordance with its bent. If any of his disciples showed an inclination for poetry, Krochmal sought to refine his taste by directing his attention to the best works in Hebrew and German literature. To another, whose fancy strayed into mysticism, he recommended the writings of Philo and Ibn Ezra, at the same time suggesting how the works of the latter should be interpreted. A third who, like Rapoport, was interested in historical researches, Krochmal instructed in the methods of critical inquiry.
