  The modern Jewish philosopher most indebted to Ibn Ezra is Nachman Krochmal. Jay Harris has argued persuasively that “Krochmal’s understanding of Ibn Ezra, and his motivation for that understanding, can only be understood as the fashioning of a response to the most interesting and serious philosophical critique of Judaism the nineteenth century produced” (Harris 1993, 144)—that is, the critiques of Hegel and Schelling. Krochmal also influenced the philological side of Ibn Ezra scholarship, for example, by casting doubt upon the authenticity of Arugat ha-Bosem; there is as yet no consensus on this issue (Greive 1973, 175–177).
