Aristotle said in Metaphysics about the Pythagoreans?
the "limited" (the odd numbers) and the "unlimited" (the even numbers) are not entities of a different order, but that the "unlimited" and unity-as-such are the subject of whatever is predicated. Which is why they consider number to be the substance of all things."
What did he mean by, and unity-as-such are the subject of whatever is predicated?
