CUSA CITES AVICENNA (IBN SINA) FOR HIS UNDERSTANDING OF SINGULARITY
there is not [in God] singularity in the sense in which our adversary conceives 
it. Rather, [there is singularity] in the sense in which Avicenna (in his 
Metaphysics [in the section] on confirming the prophet) speaks about the 
singularity of God. Here he admonishes against speaking to the people about this 
singularity - in the sense in which he enjoins that it be kept concealed - is 
Singularity of singularities. And thus God is called unsingularly Singular - 
just as [He is also called] infinite End, limitless Limit, and indistinct 
Distinction. For whoever directs his mind's eye toward the Absolute Singularity 
of all singulars sees clearly enough that the Absolute Maximum coincides with 
the Absolute Minimum, in which [Maximum-Minimum] all things are one.
