 One prominent feature in most variants of Neoplatonist thought is Negative Theology, the idea that one cannot predicate anything of God. The problems which this approach intended to avoid were two undesired implications arising from predication of a quality of God—namely, that if we attribute a particular quality to God, this quality exists co-extensively with God, and must hence be co-eternal; secondly, it introduces multiplicity to God. The Neoplatonists, in the main, wished to conceive of God as a simple and radical unity, preceding all multiplicity in the world, and as such, must precede the existence of qualities. Hence the only two allowable predications of God are God’s Unity and God’s Existence. In none of the surviving materials do we find Israeli expressing Negative Theology explicitly. Israeli’s pupil Dunash Ibn Tamim promotes negative theology in his commentary on the mystical work Sefer Yetzirah, which lead scholars Altmann and Stern (Isaac Israeli, pp. 157–8) to conclude that we can safely assume that Israeli held this opinion as well.
