This article examines the works of Adolf Jellinek (1821–1893) on the history of mysticism and the Kabbalah, which were written during his fourteen-year residence in Leipzig. It argues that studying the Spanish Kabbalists allowed Jellinek to work through ideas concerning the development of Jewish theology and the interplay of Jewish and non-Jewish philosophical perspectives. The article briefly describes Jellinek’s early education and attraction to Leipzig; his first writings on Kabbalah; and concludes with an analysis of his larger philological and genealogical projects on the authorship and literary background of the Zohar. Though Jellinek’s later prominence as a rabbi and preacher in Vienna has had the tendency to obscure his years in Leipzig, it was Jellinek’s work in Saxony that laid the groundwork for most of his subsequent scholarship on Jewish mysticism. This article is a brief introduction to this research and one more step toward revealing the still too often forgotten Wissenschaft interest in the history of Jewish mysticism.
Rabbi Eliyahu Eliezer Dessler (1892–1953) is often portrayed as antagonistic to secular studies. However, his writings show more of an intellectual hierarchy that places Torah wisdom at the top and all other wisdom a distant second. R. Dessler expended great effort promoting Torah scholarship while generally refraining from disparaging secular studies. Looking at the writings of his predecessors in the Mussar (moralist) movement, one can see that there was no disapproval of worldly education there, either: In fact, R. Dessler and his predecessors were well-educated in many secular disciplines. This essay looks to places R. Dessler’s attitude toward Wissenschaft des Judentums within the context of his life’s mission to advance talmudic study and his consequent unwillingness to countenance anything that detracted from furthering the learning of Torah. I argue that, whereas his extreme opposition to Wissenschaft was the result of his aversion to its aims, methods and conclusions, his nuanced relationship to Orthodox Wissenschaft was the result of the hierarchy through which he viewed secular as opposed to talmudic study.
Enlisted History
(2018)
Zeev Jawitz (1847–1924) was active in all spheres of culture: history, language, literature and pedagogy, all the while striving for harmonization with the Orthodox outlook. He understood that a people returning to its homeland needed a national culture, one that was both broad and deep, and that the narrow world of the Halakhah would no longer suffice. His main work was the multi-volume Toldot Israel (History of Israel, published 1895–1924) which encompasses Jewish history from its beginning – Patriarchs – until the end of the 19th century. His historical writing, with its emphasis on internal religious Jewish sources, the unity and continuity of Jewish history, and respect of Orthodox principles, comes as an alternative to the historiography of the celebrated historian Heinrich Graetz. The alternative that Jawitz tried to substitute for Wissenschaft des Judentums, was influenced not only by Orthodox ideology, which he supported, but also by his nationalist ideology. He saw himself and his disciples as the “priests of memory,” presenting the true and immanent history and character of the Jewish nation as a platform to the Jewish future in the land of Israel.
The article examines the work of Rabbi Yitzhak Isaac Halevy, arguably the most significant Orthodox response to the Wissenschaft des Judentums school of historiography. Halevy himself exemplified the Orthodox struggle against Wissenschaft, yet his work expressed a commitment to modern historiographical discipline that suggested an internalization of some of the very same premises adopted by Wissenschaft. While criticizing the representatives of Wissenschaft, Halevy was, at the same time, fighting for the internalization of its innovative characteristics into Orthodox society. He saw himself as a leader of a movement working towards the development of Orthodox Jewish studies and his application of modern historiographic principles from an Orthodox worldview as creating critical Orthodox historiography. Halevy’s approach promotes an understanding of Orthodoxy as a complex phenomenon, of which the struggle against modern secularization is just one of many characteristics.
Students of computer science studies enter university education with very different competencies, experience and knowledge. 145 datasets collected of freshmen computer science students by learning management systems in relation to exam outcomes and learning dispositions data (e. g. student dispositions, previous experiences and attitudes measured through self-reported surveys) has been exploited to identify indicators as predictors of academic success and hence make effective interventions to deal with an extremely heterogeneous group of students.
Causes for slow weathering and erosion in the steep, warm, monsoon-subjected Highlands of Sri Lanka
(2018)
In the Highlands of Sri Lanka, erosion and chemical weathering rates are among the lowest for global mountain denudation. In this tropical humid setting, highly weathered deep saprolite profiles have developed from high-grade metamorphic charnockite during spheroidal weathering of the bedrock. The spheroidal weathering produces rounded corestones and spalled rindlets at the rock-saprolite interface. I used detailed textural, mineralogical, chemical, and electron-microscopic (SEM, FIB, TEM) analyses to identify the factors limiting the rate of weathering front advance in the profile, the sequence of weathering reactions, and the underlying mechanisms. The first mineral attacked by weathering was found to be pyroxene initiated by in situ Fe oxidation, followed by in situ biotite oxidation. Bulk dissolution of the primary minerals is best described with a dissolution – re-precipitation process, as no chemical gradients towards the mineral surface and sharp structural boundaries are observed at the nm scale. Only the local oxidation in pyroxene and biotite is better described with an ion by ion process. The first secondary phases are oxides and amorphous precipitates from which secondary minerals (mainly smectite and kaolinite) form. Only for biotite direct solid state transformation to kaolinite is likely. The initial oxidation of pyroxene and biotite takes place in locally restricted areas and is relatively fast: log J = -11 molmin/(m2 s). However, calculated corestone-scale mineral oxidation rates are comparable to corestone-scale mineral dissolution rates: log R = -13 molpx/(m2 s) and log R = -15 molbt/(m2 s). The oxidation reaction results in a volume increase. Volumetric calculations suggest that this observed oxidation leads to the generation of porosity due to the formation of micro-fractures in the minerals and the bedrock allowing for fluid transport and subsequent dissolution of plagioclase. At the scale of the corestone, this fracture reaction is responsible for the larger fractures that lead to spheroidal weathering and to the formation of rindlets. Since these fractures have their origin from the initial oxidational induced volume increase, oxidation is the rate limiting parameter for weathering to take place. The ensuing plagioclase weathering leads to formation of high secondary porosity in the corestone over a distance of only a few cm and eventually to the final disaggregation of bedrock to saprolite. As oxidation is the first weathering reaction, the supply of O2 is a rate-limiting factor for chemical weathering. Hence, the supply of O2 and its consumption at depth connects processes at the weathering front with erosion at the surface in a feedback mechanism. The strength of the feedback depends on the relative weight of advective versus diffusive transport of O2 through the weathering profile. The feedback will be stronger with dominating diffusive transport. The low weathering rate ultimately depends on the transport of O2 through the whole regolith, and on lithological factors such as low bedrock porosity and the amount of Fe-bearing primary minerals. In this regard the low-porosity charnockite with its low content of Fe(II) bearing minerals impedes fast weathering reactions. Fresh weatherable surfaces are a pre-requisite for chemical weathering. However, in the case of the charnockite found in the Sri Lankan Highlands, the only process that generates these surfaces is the fracturing induced by oxidation. Tectonic quiescence in this region and low pre-anthropogenic erosion rate (attributed to a dense vegetation cover) minimize the rejuvenation of the thick and cohesive regolith column, and lowers weathering through the feedback with erosion.
