The Mutazila's Doctrine of Divine Unity Without Eternal Attributes

The Mutazila, a rationalist theological school that flourished in eighth and ninth century Basra and Baghdad, argued that affirming God's attributes, knowledge, power, will and the rest, as eternal realities existing alongside God's essence would compromise the strict unity, tawhid, that Mutazilite theologians treated as Islam's most fundamental commitment, since positing several eternal things alongside God's own eternal essence risked multiplying the eternal into something resembling several co-eternal beings rather than the single, indivisible God the doctrine of tawhid requires. Montgomery Watt's survey of Islamic creedal statements presents the Mutazilite resolution as holding that God's attributes are not separate eternal entities distinct from His essence, nor are they simply identical with it in an ordinary sense, but exist in a relationship the school's theologians worked to define carefully enough to preserve both divine unity and the meaningfulness of describing God as knowing or powerful at all. Marshall Hodgson's history of the classical Islamic world situates this position as the most theologically consequential of several Mutazilite doctrines, opposed vigorously by the later Ash'ari school, which affirmed God's attributes as real and eternal, a dispute that shaped the direction of Sunni theology for centuries after the Mutazila's own political fortunes declined.
