There has to be more too it, doesn’t there, then simply saying “no one embraces it”? It seems like that isn’t even a true statement.
Do you have a reason why you don’t think it is true beyond the assertion that no one else thinks it true (an assertion, which, I think, is falsifiable)?
That it is dead is a part of the reason. Modern science has simply overwhelmed its claims.
I think part of the reason this has happened is that we realize that things like “bread” aren’t fundamental things. They are a composite of many things, molecules, atoms, etc. So to claim that there is a metaphysical substance “bread” apart from our mind’s conception of what that words means in our language, is quite artificial, since there is also a substance “carbon” and a substance “hydrogen” and several other substances that comprise this composite substance, and even these would be comprised of more fundamental “substances.”
You see, if we posit that the substance of any item can be changed, then we posit the actual existence of these metaphysical “substances” outside of the concept of the human mind, and somewhere they
exist, and exist as part of the physical universe, which is where we cross into the world of physics.
Now, if we’re going to say that the metaphysical substance IS only of the mind and language, and we say that there is a change in the substance of the bread, that means that the change has to happen in the minds of all those who use the language that includes the term “bread”, in which case “real presence” only means that we think it’s there.
And another question arises: Has there always been a substance “bread”, even before the first human made bread? Maybe a better example is: Has there always been a substance “automobile”, even before the first one was made? It seems obvious that there was not. Thus, what is this “substance”? Where does it come from? Who creates it? The substance is nothing more than a concept of the mind expressed in language. And that’s more or less what metaphysics is. Except that Aristotle (and Aquinas and the doctrine of transubstantiation) tries to take this metaphysical concept and make it a “thing” that exists outside of language and human conception.
But, it really might be necessary to formulate a real objection to substance theory.
I don’t have to formulate a real objection as to what Kantian philosophy is dead. It just is. Why would I need to formulate something for Aristotelian ontology?
After all, you are basing your objection on knowing that atoms and subatomic particles make up matter, and, you seem to be saying that if subatomic particles make up matter then that explains the thing itself. But, since you wish to explain a thing itself by appealing to its component parts, then you must also be able to explain the component parts.
Or I can let the experts explain the component parts. Which they do.
So, what makes a subatomic particle a subatomic particle?
Again, not relevant to the conversation, as we know that all matter is made up of these things.
