Whether the formless matter of all corporeal things is the same?

❌ Objection 1 : It would seem that the formless matter of all corporeal things is the same. For Augustine says (Confess. xii, 12): "I find two things Thou hast made, one formed, the other formless," and he says that the latter was the earth invisible and shapeless, whereby, he says, the matter of all corporeal things is designated. Therefore the matter of all corporeal things is the same.

❌ Objection 2 : Further, the Philosopher says (Metaph. v, text. 10): "Things that are one in genus are one in matter." But all corporeal things are in the same genus of body. Therefore the matter of all bodies is the same.

❌ Objection 3 : Further, different acts befit different potentialities, and the same act befits the same potentiality. But all bodies have the same form, corporeity. Therefore all bodies have the same matter.

❌ Objection 4 : Further, matter, considered in itself, is only in potentiality. But distinction is due to form. Therefore matter considered in itself is the same in all corporeal things.
