criticism and the way in which they might be utilised for the purpose of historical studies; he it was who enabled them to trace the genesis of the tradition, and to watch the inner germination of that vast organism. He even indicated to them how they might continue to connect their own lives with it, how they might derive nourishment from it, and in their turn further its growth. I may assert with the utmost confidence that there is scarcely a single page in Krochmal’s book that did not afterwards give birth to some essay or monograph or even elaborate treatise, though their authors were not always very careful about mentioning the source of their inspiration. Thus Krochmal justly deserves the honourable title assigned to him by one of our greatest historians, who terms him the Father of Jewish Science. So far, I have been speaking of the importance of Krochmal’s treatise and of its significance in the region of Jewish Science. It is necessary, I think, to add a few words with regard to the general tendency of his whole work. I have already alluded to the characteristic modesty of Krochmal; I have pointed out how little he cared for publicity, how dearly he loved retirement. The question accordingly presents itself—What can have been the real and sufficient causes that prevailed upon him to yield to the solicitations of his friends and to write upon what the Talmud would term “matters standing on the heights of the world”? The answer to this question may, I think, be found in the title of Krochmal’s book, the _Guide of the Perplexed of the Time_. It is indeed a rather unusual coincidence for the title of a Hebrew book to have any connection with its subject matter. The same merit is possessed by the _Guide of the Perplexed_ of Maimonides, the title of which undoubtedly suggested that of Krochmal’s treatise. There is, however, one little addition in Krochmal’s title that contains a most important lesson for us. I mean the words “of the Time.” By these words Krochmal reminds us that, great as are the merits of the immortal work of Maimonides—and it would be difficult to exaggerate its value and importance—still it will no longer suffice for us. For, as Krochmal himself remarks, every time has its own perplexities, and therefore needs its own guide. In order to show that these words are no idle phrase, I shall endeavour to illustrate them by one example at least. In the _Guide of the Perplexed_ of Maimonides, Part II., Chapter XXVI., occurs a passage which runs thus: “In the famous chapters known as the ‘Chapters of R. Eliezer the Great,’(39) I find R. Eliezer the Great saying something more extraordinary than I have ever seen in the utterances of any believer in the Law of Moses. I refer to the following passage: ‘Whence were the heavens created? He (God) took part of the light of His garment, He stretched it like a cloth, and thus the heavens were extending continually, as it is said (Ps. civ. 2): He
