Philo did not consider God similar to heaven, the world, or man; his God existed neither in time nor space and had no human attributes or emotions. He argued that God has no attributes (ἁπλοῡς), in consequence no name (ἅρρητος), and for that reason he cannot be perceived by man (ἀκατάληπτος). Further, God cannot change (ἅτρεπτος): He is always the same (ἀἱδιος). He needs no other being (χρήζων ὁυδενòς τò παράπαν), and is self-sufficient (ἑαυτῷ ἱκανός). God can never perish (ἅφθαρτος). He is the simply existent (ó ὤν, τὸ ὅν), and has no relations with any other being (τὸ γὰρ ἢ ὄν ἒστιν ουχὶ τῶν πρός τι).
