 God is simple being because He is described by being, and being is a unique, simple reality. It is simplicity devoid of essence (Mulla Sadra 2001–5, VI: 45–51). That simplicity is uncontaminated by multiplicity, privation, imperfection or any such negative property. God’s existence is pure and unencumbered by complexity such as an essence that might raise questions of genera, division, composition and definition.
