In theology, the doctrine of divine simplicity says that God is without parts. The general idea of divine simplicity can be stated in this way: the being of God is identical to the "attributes" of God. In other words, such characteristics as omnipresence, goodness, truth, eternity, etc. are identical to God's being, not qualities that make up that being, nor abstract entities inhering in God as in a substance. Varieties of the doctrine may be found in Jewish, Christian, and Muslim philosophical theologians, especially during the height of scholasticism, though the doctrine's origins may be traced back to ancient Greek thought, finding apotheosis in Plotinus' Enneads as the Simplex.
