of Cusa, On God As Not-Other
The late Cusan treatise “Vom Nichtanderen” (1462/63) deals with the nature, being and knowability of God. It is a speculative theology with a methodological-philosophical claim. God is defined here by the non-other, which is considered the essence of the definition, since it defines itself and everything else. The definition of the non-other is: “The ‘non-other’ is nothing other than precisely the ‘non-other’.” (non aliud est non aliud quam non aliud). The reason why the non-other is the essence of the definition, why it therefore defines everything else and itself, is the fact that everything that is is precisely nothing other than what it is.
