L2, you have evaded the black and white questions I asked.Oh, yes. But I would not restrict myself to Porphery’s Tree because the ancients ( including Aristotle ) restricted substance to material being. St. Thomas did not do so, he used a modified " tree " based loosely on Aristotle. In Thomas’ view a substance is any being ( something which exists in any way ), material or spiritual, which existed in reality, which was not a " being of the intellect. "
So the soul and man compose one substance. The soul is not a separate substance in man, nor is the body a separate substance in man. When they are together there is only one substance, the human being, man’s matter and his substantial form. The soul however can exist without the body, which is what this arguement is all about. Alone one would have to say that the soul is an incomplete substance, a " fish out of water " so to speak, a modified substance, a substance lacking something it properly needs - its body. I think Thomas would describe it as a " deprived substance, " or something like that. ( you can look it up if you like, I’m going from memory.).
The soul however is a spiritual substance, not a material substance. And by " spiritual, " I mean a substance or being having no physical constitution of any type, however subtle it may be imagined - utterly simple, limited only by its act of existence.

What you write makes no sense until we clearly define the terms used.
You must know that the Scholastics adapted Porphery’s Tree to include Incorporeal Substance. (The issue is not what particular names any given age gives to the Tree’s branches, its just a means of defining terms at a global level.)
Your comments about Aristotle’s version are spurious and of no consequence.
Ditto for the link site where you went off on tangents.
Just face the question. You must know that Aquinas divided all being into either corporeal or incorporeal substances.
So allow me to repeat the tough questions for a 3rd time:
(1) Where on Porphery’s Tree (of 'Substance") do we place the substance that is “Man”?
(ie under “incorporeal substance” or under “corporeal substance”).
(2) Where on Porphery’s Tree (of 'Substance") do we place the substance that is “Soul?”
(ie under “incorporeal substance” or under “corporeal substance”).
(3) Is human death a “substantial change” or an “accidental change” wrt the substance Man?
If you cannot answer each of these questions in one short sentence then, as my boss puts it, “you don’t actually know”.
That’s fine. But if you are averse to answering these questions then we cannot continue our discussion because our terms will be too slippery and ambiguous.
BTW, “So the soul and man compose one substance” (I think you mean “soul and body” perhaps) sounds like philosophic self-contradictions to me, but we cannot analyse this until you answer the above questions.
