I wondered if you would go down this road. It's a strange one for materialists to take. You've blundered (either knowingly or unknowingly) into the Ship of Theseus problem. Namely, how much change does a thing have to go through before it's not the same thing anymore.
Seriously? Is dishonesty all you have left?
Read your own words, Fud.
What is, in fact, a "two-headed coin"? Unless you are arguing from an antinomian stance (that is, that words have no real meanings), a "two-headed coin" is, in fact, a coin with two faces that show "heads". Now pay attention,because this is where you founder.
If a coin has
less than "two heads"; that is, if a coin has a "tails" face, or
TWO "tails" faces, it is not, by definition, a "two-headed coin". If the label, "two-headed coin" means anything at all, it must refer to a "coin-with-two-heads"--coins with less than two heads need not apply as they do not qualify, by definition.
If you, by your eldridtch magicks,
change a "coin-with-two-heads" into "...something entirely else..." (your words); it is no longer what it was. If it no longer has two "head"-faces, it is no longer a "two-headed coin". (if your legerdemain, for instance, could
change a 2€ coin into a 100¥ coin, after the change, it would no longer be European currency, by definition. It would have been changed, as you say, into "...something entirely other..."; no longer what it was.)
A "bachelor" is not the same thing as a "married man"; it is, in your words, "...something entirely other...",if you intend to be taken as using words in any way correctly, or accurately.
Slow, you are a particular person. Would you say you're essentially the same person you were five minutes ago? Many, many atoms have migrated into and out of your body in that time. Does your identity change with each changing particle, or are you still essentially you?
I wonder if you realize how weak your attempt to torture an analogy makes your argument seem?
In 5 minutes? Not enough "change" to notice; certainly not as much change as (for instance) no longer having two heads, or no longer being single.
5 years ago? I was (measurably, and recordedly) 10-15 IQ points smarter, with better concentration, more patience, and better linguistic facility (sever cerebral trauma will do that). I would not disagree that I am not the same person I was, and that that person no longer exists.
30 years ago? I was white-knuckling heteronormativity, fideonormativity, and socionormativity. i am (thankfully) no longer that person.
45 years ago? Although "the child is the father of the man", the child I was no longer exists; I am not that child.
As distinct, and as irreversible, as those changes have been, none of them are as definitive as a "coin-with-two-heads" being
changed into a "coin-with-at-least-one-tail-to-land-showing".
In case you missed it,
"coin-with-two-heads" =/= "coin-with-one-tails" =/= coin-with-two-tails"
You are claiming that the bachelor (who doesn't even undergo a physical change when he gets married) "ceases to exist". If you were to tell him that he doesn't exist anymore, you would have quite an argument on your hands!
No, but if I were to tell him he was, in fact, no longer a bachelor, he would agree with me (absent a commitment to antinomianism). he could, in fact, face certain legal penalties for
claiming to be a bachelor (although married); in fact, he
no longer fits the definition of "bachelor", and is, in fact (do pay attention) NOT a "bachelor".
"Did you see a bachelor come though here?"
"No, but I did see a married man."
Or maybe you believe that a thing ceases to exist if one tiny change is made.
How "tiny" is a change that sunders a thing from its definition?
A "coin-with-at-least-one-tails-to land-showing" is not the same as a "coin-with-two heads". Do you really want to claim that ias a "tiny" change?
Tell you what: take your "two-headed coin" (by your argument, a "tiny change") to the bank; try to use it to pay a legal debt. Let the Treasury Dept. explain to you how "tiny" that change is...
Is that what you believe? If the two-headed coin changes so that one side is now tails, is there now a brand new coin?
By definition, yes. If the coin
was a "two-headed coin", and now has some-number-other-than-two-heads, it is not (barring a specious commitment to antinomianism) a "two headed coin", but "...something entirely other..." (your words).
If a coin has two tails, or one tail, it is not,
by definition, a "two-headed coin", but "...something entirely other..."
If a coin has multiple holographic programmable faces, it is not a "two-headed coin", but "...something entirely other..."
Are you dishonest enough to claim otherwise?
Are you a completely different person with each breath you take? You could take that position, of course, but it is a very strange one.
Is a coin-with-other-than-two-heads a "two-headed coin"? You could take that position, of course, but it would be a very strange one; nor would it be a defensible one.
