Levi b. Abraham b. Ḥayim, a popularizer of rationalist philosophy activearound 1300 in Occitania, was identified as a transgressor by proponents of aban on the study of philosophy. The nature of Levi's transgressiveactivities and the reasons why he was targeted have remained elusive, though aconsensus view suggests that his socioeconomic standing and genuinely radicalideas contributed to his being singled out. In fact, a careful reassessment ofthe extant sources demonstrates that Levi, as an established member of the eliteclass, was an inadvertent target, identified in the course of a misunderstandingbetween Solomon Ibn Adret and his confidant in Perpignan, Crescas Vidal. No moreradical than others and one of many popularizers of rationalism, Levi became aconvenient exemplar and test case for ban proponents. They struggled to definethe nature of Levi's potentially dangerous effects on his students,however, and Levi remained an equivocal figure even to his detractors. Thoughvilified and forced out of the home of his patron, Levi was accorded basicrespect and often defended; he was never subject to excommunication, censure, orany type of halakhic prosecution.
