9th century philosopher and theologian who translated Pseudo-Dionysius thus was heavily influenced by him.
'God is beyond all meaning and intelligence, and he alone possesses immortality..
'His light is called darkness because of its excellence'
Similarly to Pseudo-Dionysius, Eriugena believes that because God and humanity are at an epistemic distance, humans are physically incapable of describing what God is like.
It is impossible to refine God into a human description because he is beyond this.
God is a mystery to all humans, we are unable to comprehend him.
'We do not know what God is. God does not know what God is because God is not any created thing. Literally God is not, because God transcends being'
When Eriugena says 'God is not', he doesn't mean there is no God, but rather he means God can't be said to exist in the way that other things exist in this world. We cannot equate God to the profane. Using apophatic/via negativa language to show God is different from those in our realm. Eriugena's ideas stop us from anthropomorphising God, and labelling human attributes onto God
