“Now it cannot subsist of itself, as the Philosopher proves (Metaph. vii, 26, 27, 29, 51) , because sensible matter belongs to the specific nature of sensible things, and is placed in its definition, as flesh and bones in the definition of man. Hence human nature cannot be without sensible matter. Nevertheless, if human nature were subsistent in this way, it would not be fitting that it should be assumed by the Word of God. First, because this assumption is terminated in a Person, and it is contrary to the nature of a common form to be thus individualized in a person.” source
