Plotinos: Complete Works, v. 1 In Chronological Order,...

Is the infinite identical with the essence of the infinite? There is a distinction between them where there is reason and matter; where however matter is alone, they must be considered identical; or, better, we may say absolutely that here below the infinite does not occur; otherwise it would be a reason, which is contrary to the nature of the infinite. Therefore matter in itself is the infinite, in opposition to reason. Just as reason, considered in itself, is called reason, so matter, which is opposed to reason by its infinity, and which is nothing else (than matter), must be called infinite.
