THE MIRACLE IS THAT MATTER PARTICIPATES IN EXISTENCE WITHOUT PARTICIPATING IN IT.
It is indeed impossible that that which is outside of existence should be completely deprived of it; for the nature of existence is to produce beings. On the other hand, absolute nonentity cannot mingle with existence. The result is something miraculous: matter participates in existence without really participating in it, and by approaching to it obtains something, though by its nature matter cannot unite with existence. It therefore reflects what it receives from an alien nature as echo reflects sound in places that are symmetrical and continuous. That is how things that do not reside in matter seem to reside in it, and to come from it.
