Concepts are mental constructs alone. They often indeed "piont" to actual things, and they may (or may not) be accurate. But they are still mental constructs, and therefore ephemeral (not primal). When I die, my specific concepts die with my brain (unless I have taken the time to communicate them in some fashion).
Concepts refer to objective characteristics which do not cease when you die. The heat of fire is perceptual and you form the concept "hot" from it. Does that concept die with you? No. YOUR brain and YOUR subjective sense of pain from what is HOT dies and not the referent which imparted the characteristic to you.
See the difference?
The Universe is objective. The characteristics of things are there. If each thing had no defining or identifying characteristic objective to itself-----we could not detect the difference between a lemon and a titmouse!
What you hold in your own mind is like your drawing of the nude lady in art class. How good of an artist are you? THAT is how accurate your drawing is. But, the nude lady is objective.
Science gives us photographs instead of drawings (to continue the analogy).
For arguementation's sake, though, it's easy to label any concept you personally disagree with as a "false concept
No.
If I call the lemon in your iced tea a titmouse it is easy enough to see whose concept is false!
Remember, concepts are connected to actually existing things!
We work with artifical concepts all the time. Does a corporation "exist"? As legal fiction, yes - but it has no specific physical body that you can point to. It can own assets and incur debt, and is a useful concept - but as a "real entity", it is as sorely lacking as the Trinity in your position.
Ahhhh, this is a secondary level of Concept. Concepts made from other Concepts! An abstraction FROM abstractions themselves.
In the case of a Corporation the "Corp" is a representative body or "body". It stands for the owners. A corporation can be sued. If the corporation did not "exist" what would be the point in suing it?
The name of a Corporation is Fiction, but, not the Corporation itself. A Corporation has assets real enough to make lawsuit worthwhile.
We talk about theoretical science. There is actually no proof that Relativity is accurate. We conclude that it is because it is a useful predictor for objects at the macro level. Is Relativity "real"? There is no proof that matter is made up of strings. Is String Theory "real"? Does it point to something "real"?
Relativity Theory describes something in the way of behavior which has, as I recall, been tested (Michaelson-Morley is what comes to mind, I'm too lazy to search.)
But---I'm afraid your departure into the rarefied atmosphere of Theoretical Physics is more a deflection than a rebuttal.
The concepts we use by the millions each day enable us to perform laser surgery on the eye, design space shuttles that travel millions of miles and deploy photographic appartus which sends back digital photos from the surface of Mars! Proof? You need more proof???
As far as the Trinity goes, no specific person has to have seen this Trinity to create a concept about it. I have never seen the Prime Minister of Israel. But I get the concept. I don't even have to believe in the Trinity or the Prime Minister of Isreal in order to conceptualize them.
Special Pleading is a fallacy, as you well know. The Trinity is as vulnerable to our analysis as any other concept and we can reserve no special Plea on its behalf.
The key element to the Concept of Trinity we can defeat immediately is the inherent self-contradiction of pleading IDENTITY for each constituency of PERSON and calling them each/all EQUAL. It is most clear from the referent (if you want to call the Bible a referent) that the Father is prior to the son. (Otherwise, the term "Father" is meaningless) The Son is inferior in knowledge to the Father. The Son begs the Father to grant that "this cup might pass" and, thus, demonstrates a difference is WILL and HIERARCHY in a power arrangement. The Holy Spirit doesn't say much......:)
KNOWING THE DIFFERENCE between conceptualizing a FICTION and a REALITY is what RATIONALITY is all about! Or, did you miss that?
