 Nature is defined as universitas rerum, the “totality of all things”, and includes both the things which are (ea quae sunt) as well as those which are not (ea quae non sunt). This divine nature may be divided into a set of four “species” or “divisions” (divisiones) which nevertheless retain their unity with their source. These four divisions of nature taken together are to be understood as God, presented as the “Beginning, Middle, and End of all things”.
