JOEL, MANUEL (1826–1890), rabbi and scholar. Joel, who was born in Birnbaum, Poznan province, was the son of the local rabbi. He studied classics and philosophy at Berlin and obtained a doctorate at Halle. In Berlin he came under the influence of Leopold *Zunz and M. *Sachs. Joining the staff of the *Juedisch-Theologisches Seminar in Breslau on its foundation in 1854, he taught classical languages, religious philosophy, and homiletics
Joel's scholarly importance lies mainly in the field of religious philosophy. He wrote on Ibn Gabirol, Maimonides, Crescas, and Levi b. Gershom, investigating their Greek and Arabic sources, and their influence, in turn, on Christian scholasticism and Spinoza. These essays were collected in his two-volume Beitraege zur Geschichte der Philosophie (1876). His two-volume Blicke in die Religionsgeschichte… (1880–83) was an important and influential contribution to comparative religion. Joel presented (apart from his sermons) his own religious philosophy, based on Kant and also on Schleiermacher's religion of emotion, in his Religionsphilosophische Zeitfragen (1876) and in a posthumously published article "Mosaismus und Heidentum" (in JJGL, 7 (1904), 35ff.), as a belief in revelation as the "thinking of the heart."
