Parts are less real than wholes. IOW, parts only exist virtually until removed from the whole. For example, a splinter only exists when it is removed from a piece of wood. Splinters only exist when they are extracted.
The heart exists virtually inside a man until it is removed.
A man is alive. The heart moves in virtue of his soul. The heart is not a thing that lives distinct from the thing that animates it.
I’m not sure that I can agree that parts are less real than wholes, at least not speaking absolutely. It depends on the “whole” in question. After all, is a class more real than the students that make it up? Sometimes the whole is virtual, and the parts are real. I believe I understand the point you’re trying to make, but I’m not sure that we can make such statements easily when it comes to the human person.
What I would say is that the heart is the heart of a man by definition, and is therefore defined by its relation to a particular man. That the heart is alive is indisputable, at least by all empirical definitions, so by Catholic belief it is animated by a soul. Is this the soul of a man, or is it a vegetative or animal soul?
Once the heart is removed, it exists as an independent thing. It is alive? If so, what spirit animates it? It moves on its own accord which implies it is alive. My opinion at this point is that it as a thing independent from a man has --once independent-- a material spirit. I conclude this because left to it’s own devices, it will never reason. We analyze the nature of things in order to understand their essences.
A child with severe brain damage will never reason, but we consider them a man. A person in a persistent coma will never reason, but we consider them a man. We can’t say that actually reasoning makes a man, and we can’t say that the physical capacity to reason makes a man; we can say that the spiritual capacity to reason makes a man, but we can’t p(name removed by moderator)oint when the spiritual soul ceases to enliven a body. We can say that the spiritual soul has the power to reason, but without the ability to identify where a spiritual soul resides and where it doesn’t this statement doesn’t amount to much. All we can do is say that a thing that reasons has a spiritual soul, but we can’t say that a thing that doesn’t actually reason does not have a spiritual soul, unless we are willing to deny a spiritual soul to the sleeping, the comatose, and the newborn.
If the capacity for actual reasoning is not the basis for determining humanity, then what makes the heart different from the man in a persistent coma? What makes the heart different from the man in a persistent coma who has lost their arms and legs, and therefore is only part of the man they once were? If the heart does not require an immaterial soul because it can’t reason, then what makes us think that the man in a coma has an immaterial soul? Do the severely mentally disabled have immaterial souls? At what point does the body cease to be united by a rational soul and become a mere collection of organs?
