The same consideration forced him to shield himself behind a pseudonym in publishing his anti-hasidic satire _Dibre Tzaddikim_, "The Words of the Tzaddiks," [1] (Vienna, 1830), a rather feeble imitation of _Megalle Temirin_, the Hebrew counterpart of the "Epistles of Obscure Men," by Joseph Perl.

[2] His principal work, entitled _Bet Yehudah_, "The House of Judah," a semi-philosophic, semi-publicistic review of the history of Judaism, remained for a long time in manuscript.

Levinsohn was unable to publish it for the reason that even the printing-press of Vilna, the only one to issue publications of a non-religious character, was afraid of bringing out a book which had failed to receive the approbation of the local rabbis.

Several years later, in 1839, the volume finally came out, clothed in the form of a reply to inquiries addressed to the author by a high Russian official.
