  Isaac Husik marks Ibn Ezra’s role in the transmission of Andalusian wisdom, which consists of “grammar… mathematics and astronomy…the philosophy of Neo-Platonism, and the scientific and rationalistic spirit generally” (Husik 1969, 187). Like Guttmann, Husik calls attention to the affinity between Ibn Ezra and Ibn Gabirol. In 1973, Hermann Greive published a book-length study of Ibn Ezra under the title, Studien zum Jüdischen Neuplatonismus. Greive paid particular attention to Ibn Ezra’s psychology; this is indeed the branch of philosophy to which Ibn Ezra was most strongly attracted, and the topic exploited most intensively by specialists in Ibn Ezra (Tanenbaum 1990; Levin 1992). However, Greive is well-aware that the presence of neoplatonic teachings in Ibn Ezra’s writings does not mean that Ibn Ezra’s allegiance was limited to that school exclusively.
