What Is Primary Matter?

Aristotle says there must be something continuous from the old thing to the new and it's called primary matter. Primary matter does not exist on its own. It's a constitutive principle of substances, but not an element or an ab. What is primary is pluripotentency. You could go further and say it's omnipotency. It's potentiality to all forms, to all natural forms. That's what it is. I don't know a lot of science, but I know that sometimes you use the word pluripotentencies or pluripotentya. But nothing comes from nothing according to our fourth principle.
