  MANASSEH BEN JOSEPH OF ILYE
  By : Solomon Schechter Herman Rosenthal
        
         Russian rabbinical writer and philosopher; born at Smorgon,
  government of Wilna, 1767; died at Ilye, in the same government, 1831.
  At seven years of age he was acquainted with some original sources in
  rabbinical literature, but his father would not permit him to study
  Hebrew grammar and the Bible lest these might interfere with his
  Talmudic studies. According to the custom of that time Manasseh was
  married early; at the age of thirteen he became the husband of the
  daughter of a wealthy citizen of Smorgon; but he soon divorced her and
  married Sara, the daughter of a merchant in the village of Ilye, where
  he spent most of his life. His erudition early drew a circle of
  friends and disciples around him, and in discussing with them the
  rabbinical laws and regulations he did not hesitate to criticize such
  authorities as the Shulchan 'Aruk and Rashi. He even dared to
  interpret some parts of the Mishnah in contradiction to the
  explanation given by the Gemara; for such daring he probably would
  have been put under the ban had not an influential rabbi, Joseph Mazel
  of Wyazyn, come to his rescue. The latter took great interest in
  Manasseh and threw open to him his extensive and valuable library of
  rabbinical and philosophical literature.
        Relation to Elijah of Wilna.
  Manasseh became acquainted also with Elijah Gaon of Wilna, whom
  he visited once a year; but when Elijah discovered that Manasseh
  visited Zalman of Liozna, the leader of the northern Chasidim, he
  credited those of his disciples who asserted that Manasseh showed
  Chasidic leanings, and held aloof from him, though Manasseh explained
  to the gaon that only a love of knowledge induced him to visit Zalman,
  and that his views differed widely from those of the Chasidim.
  Manassch really sympathized somewhat with the latter, expecting that
  their movement might develop into something better than the existing
  rabbinical orthodoxy. In his writings Manasseh holds Elijah of Wilna
  in high esteem, declaring in "Binat Michra" (Grodno, 1818) that from
  him he had learned to interpret the Talmud by the simple philological
  method of the "pesha," while the majority of Talmudic teachers used
  the less scientific methods of the "derash. "He even says that but for
  Elijah of Wilna the Torah would have been forgotten in Israel ("Alfe
  Menashe," § 102; comp. § 177).
  The suspicions of the Orthodox members of Manasseh's community
  increased when he began to study philosophy, mathematics, and
  astronomy. He had formed the resolution to go to Berlin for the
  purpose of becoming acquainted with the circle of Moses Mendelssohn;
  but at Königsberg he was stopped by some of his Orthodox
  coreligionists, who induced the Prussian authorities to refuse him a
  passport. Thus he was forced to return home, where, with the sole aid
  of some old manuals, he studied German, Polish, natural philosophy,
  and mechanics.
  Shows Advanced Tendencies.
  Manasseh had large ideas of educating the Russo-Jewish youth, but
  the rabbis of his time were not prepared to accept them. In his
"Pesher Dabar" (Wilna, 1807) he complains "that the Jews are divorced
  from real life and its practical needs and demands; that the leaders
  of the Jews are short-sighted men who, instead of enlightening their
  followers, darken their intellect with casuistic restrictions, in
  which each rabbi endeavors to outdo his predecessors and
  contemporaries. The wealthy class thinks only of its profits, and is
  not scrupulous with regard to the means of getting money. Even those
  who are honest and endeavor to help their poorer brethren do it in
  such an unintelligent way that they do harm rather than good. Instead
  of educating the children of the poor to become artisans, they add to
  the number of idlers, and are thus responsible for the dangerous
  consequences of such an education." Plungiansky (see bibliography) is
  of the opinion that these words were directed against Elijah; and from
  the preface to "Pesher Dabar" it is evident that Manasseh desired to
  make peace between the leader of the Chasidim and the gaon. The
  consequences to the author of this daring appeal to the rabbis were
  serious; many rabbis destroyed his book, and some of his disciples and
  nearest friends left him.
  Manasseh's father-in-law having lost his fortune, Manasseh left
  his native town and went to Brody, where he made the acquaintance of
  R. Jacob Landau, who expressed his disapproval of Manasseh's radical
  criticism of Rashi. He went next to Brest-Litovsk, where R. Aryeh Löb
  Katzenellenbogen engaged him as teacher to his sons, on the express
  condition that he adopt the interpretation of Rashi. Manasseh,
  however, could not abandon his critical methods, and, being dismissed,
  returned to Ilye. During his stay in Volhynia, on his way to Brody,
  Manasseh had begun to print his "Alfe Menashsheh," but when the
  printer became acquainted with the radical spirit of the work he threw
  both proofs and manuscript into the fire. Manasseh at once proceeded
  to rewrite his book, and owing to his remarkable memory was able to
  complete it; he published it in Wilna in 1827 (republished in Warsaw
  in 1860 In this work Manasseh demonstrates that in accordance with the
  rabbinical teachings the Rabbis have the power to amend certain Jewish
  legal decisions when there is a necessity for it. Manasseh was
  compelled to suppress the paragraph containing this (§ 20) because
  Samuel Katzenellenbogen threatened that if it were not withdrawn he
  would order the work publicly burned in the synagogue-yard.
  When the Russian government ordered the establishment of
  rabbinical schools, Manasseh wrote a work on higher mathematics,
  mechanics, and strategics and asked his friends to induce some scholar
  to translate this work into Russian in order to show the government
  what a Jew could produce on those lines. His friend Joseph of Wyazyn
  feared, however, the unfavorable comment of the officials, who might
  say that the Jews, instead of working on farms, were preparing war
  plans. It was resolved therefore to burn the manuscript. Judah Löb of
  Kovno, Samuel Eliasberg, and Wolf Adelsohn may be mentioned among
  Manasseh's friends.
  Manasseh was undoubtedly a great scholar, and his mind was
  remarkable for subtlety and power of analysis; he was also a friend of
  the people, and translated his "Samma-de-?ayye" into Judæo-German for
  the purpose of reaching them. In another work, "Shekel ha-kodesh"
  (Shklov, 1823), he defends himself against the accusation of being an
  ambitious innovator. He says that his opponents can not even
  understand that one can risk his peace by antagonizing influential
  rabbis out of mere love for one's people. He asserts that he never
  sought wealth, fame, or pleasure, and that he lived on bread and
  water; but that the thirst for self-perfection would not allow him to
  rest until he had fulfilled his mission. In the same book he shows
  that it iserroneous to suppose that the earthly life is only a vale of
  tears and misery and the antechamber to a future life.
  Manasseh was one of the first victims of the cholera epidemic of
  1831. He did not live to realize any of his aspirations, but he
  prepared the ground for the Maskilim, who disseminated his ideas.
  Besides the above-named works Manasseh left one on mathematics and
  some other writings in manuscript.
  Here is another excerpt from an article on another site:
  Towering above all the disciples of the Gaon, the most outspoken in
  behalf of enlightenment is Manasseh of Ilye (1767-1831). At a very
  early age he attracted the attention of Talmudists by his originality
  and boldness. In his unflinching determination to get at the truth, he
  did not shrink from criticising Rashi and the Shulhan 'Aruk, and dared
  to interpret some parts of the Mishnah differently from the
  explanation given in the Gemara. With all his admiration for the Gaon,
  but for whom, he claimed, the Torah would have been forgotten, he also
  had points of sympathy with the Hasidim, for whose leader, Shneor
  Zalman of Ladi, he had the highest respect. Like many of his
  contemporaries, he determined to go to Berlin. He started on his way,
  but was stopped at Königsberg
  {121}
  by some orthodox coreligionists, and compelled to return to Russia.
  This did not prevent his perfecting himself in German, Polish, natural
  philosophy, mechanics, and even strategics. On the last subject he
  wrote a book, which was burnt by his friends, "lest the Government
  suspect that Jews are making preparations for war!" But it is not so
  much his Talmudic or secular scholarship that makes him interesting to
  us to-day. His true greatness is revealed by his attempts, the first
  made in his generation perhaps, to reconcile the Hasidim with the
  Mitnaggedim, and these in turn with the Maskilim. He spoke a good word
  for manual labor, and proved from the Talmud that burdensome laws
  should be abolished. His Pesher Dabar (Vilna, 1807) and Alfe Menasheh
  (ibid., 1827, 1860) are monuments to the advanced views of the author.
  In the Hebrew literature of his time, they are equalled only by the
  'Ammude Bet Yehudah and the Hekal 'Oneg of Doctor Hurwitz.15

        This is the review of the book, The author of the review s who sent me
  the two Hebrew articles:
        Manasseh of Ilya and Y. Barzilay
        
        I recently finished reading Yitzhak Barzilay's book on R. Manasseh of
  Ilya. R. Manasseh was a fascinating character. He was a student of the
  Vilna Goan, but wrote a pamphlet arguing for reconciliation between
  Hassidim and non-Hassidim. He wrote another work discussing the trop
  or cantilation marks and yet another, his mangum opus, on the Talmud.
  It is the later work that he is most well known for, although not
  necessarily in a positive way. The Tefferet Yisrael (R. Yisrael
  Lifshitz) on the Mishna quotes a brief passage from this commentary.
  R. Menasseh's comments appear on the first Mishna in Perek Alu
  Mitzhut. (Baba Metziah 1:1). He understands the Mishna in a different
  fashion than the Talmud, thus provoking some to argue such a position
  is heritical.
        R. Manasseh was a controversial figure. His book on the
  reconciliation, Pesher Davar, was publicly burnt. His work on Talmud,
  Alphei Menashe, after either the publisher or some outsider (depending
  on the source, there are a couple versions of the story), destroyed it
  right before it was completed. R. Manasseh was forced to reproduce the
  entire work from memory and find a different printer.
        Additionally, although he had a close relationship with the Vilna
  Goan, the Vilna Goan severed that relationship after learning R.
  Manasseh had been in contact with R. Shneur Zalman of Lida (Ba'al
  haTanya).
        All this being said, he is ripe for an excellent biography.
  Unfortunately, Barzilay does not deviate from his norm, and put out
  another poor work. Although Barzilay has written on many other
  interesting figures of Jewish history, almost always he fails to do
  anything substantive or worthwhile with the subjects.
        This work is full of gross supposition that are never supported by any
  facts. For instance we have sentences like this "It may be assumed
  that in a talented person like Manasseh, his critical faculties must
  have awakened rather early, and already in his youth he may have
  arrived at some of his nonconformist views with regard to the Halakhah
  and its historical development." (p. 24). Therefore, Barzilay wants to
  then claim and project back on Manasseh's early years and label him as
  a radical even then based only upon "his critical faculties." While
  that may be the case, there are also a million other possibilities.
  For instance, Manasseh was influenced later in life by someone else or
  he came to his "nonconformist views" based upon years of study and
  when he was 17 (according to Barzilay, again a guess) he did not hold
  these views.
        Another example, where Barzilay is discussing Manasseh's frequent
  trips to his wealthy relatives house who had a terrific library,
  Barzilay makes the following statement: "The role of this library in
  Manasseh's life and intellectual growth cannot be overestimated . . .
  It may be further assumed, with a high degree of probability, that
  there also were to be found there the recent works of the Berlin
  maskilim, as well as those of the enlightened orthodox Jews from both
  Eastern Europe and the Germanies." Barzilay then goes on to cite to
  the many subscribers of various haskalah literature as "proof" this
  library contained these books. There a basic problem with this
  argument. Since Barzilay is able to point to where these books went to
  as the subscriber list, lists both person and place, why then isn't
  this rich relatives name ever listed if he was a collector of such
  works? Instead, Barzilay is satisfied to assume that the books were
  there as there were many haskalah books that "found [their] way among
  the Jews of Eastern Europe."
        These are but two examples from a book that is rife with such sloppy
  work. The only redeeming fact of the book is the extensive quotation
  from R. Manasseh's works. As mentioned above, this is not the first
  book Barzilay wrote that fails miserably. He also did another
  biography on R. Shlomo Yehudah Rapoport (Shir), the son-in-law of the
  Ketzot HaChoshen and one of the leading figures of 19th century
  Eastern European Haskalah. This book is also disappointing.
        unfortunate, the only other biography, Ben Porat Yosef, is no gem
  either. It was written by Mordechai Plungian an editor at the famed
  Romm press. This is more of an anecdotal than scholarly work. However,
  this work got Plungian in trouble as some claimed he attempted to make
  R. Manasseh into a maskil.
        What is particularly strange is that a book review of Plungin's book
  appeared in HaMagid. At the JNUL site, which contains old Hebrew
  newspapers, the version they have appears to have that portion blacked
  out. The review in question appeared in HaMagid on March 8, 1858.
        The full citation for Barzilay's book is Manasseh of Ilya: Precurser
  of Modernity Among the Jews of Eastern Europe (Manges Press, 1999).
