To begin with, we have the controversy with the Stoics, which,
though it appears in the works of both, bears in each a different
significance. While with Numenius it absorbed his chief controversial
efforts,[673] with Plotinos[674] it occupied only one of his many
spheres of interest; and indeed, he had borrowed from them many
terms, such as "pneuma," the spiritual body, and others, set forth
elsewhere. Notable, however, was the term "hexis," habituation,
or form of inorganic objects,[675] and the "phantasia," or
sense-presentation.[676] Like, them, the name A-pollo is interpreted as
a denial of manifoldness.[677]
Next in importance, as a landmark, is Numenius's chief secret, the name
of the divinity, as "being and essence," which reappears in Plotinos in
numberless places.[678] Connected with this is the idea that essence is
intelligence.[679]
