Mieses was a strong opponent of Hasidism. His main work, Kin'at ha-Emet (Vienna, 1828; 2nd ed., Lemberg, 1879),[2] contains an introduction and three dialogues between Maimonides and Solomon of Chelm. In it Mieses advocates for a "pure Judaism" free from superstitious beliefs. He sharply criticizes Hasidic leaders for spreading superstition, and for exploiting the credulity of the ignorant masses. He appends to his book, under the title Likkute Feraḥim, extracts from the writings of Judah ha-Levi, Joseph ibn Ezra, Kimhi, Albo, Abravanel, Joseph Delmedigo, and others, in support of his views.
He also wrote additions to David Caro's Tekunat ha-Rabbanim,[3] which include a plan for modern Jewish education.[1]
