  The two most “philosophical” of his writings are Hayy ben Meqitz, a poetic visionary recital to be discussed in a separate section below, and Arugat ha-Bosem.  The latter is also poetic in style. The doctrine it presents, for example atomism, is very much part and parcel of the kalam tradition, rather than philosophy, strictly speaking. For that reason, Ibn Ezra’s authorship has been called into question (Greive 1973, 181–189, including German translation of the entire text). However, even such a committed neoplatonist as Isaac Israeli had no compunction about contributing to the kalam, and there is no reason a priori to think that the situation would have been different for Ibn Ezra. Allegiances to streams of thought in that period were not necessarily exclusivist.
