A Fault in Carrier's Logic Perception


Correspondence of Hans Georg Lundahl : With Richard Carrier · Carrier carries on the obtusity on a key point ... · somewhere else : Two Observations, Carrier! What if logically necessary means God? · Various Responses to Carrier · A Fault in Carrier's Logic Perception

As you may have perhaps gathered from previous two posts on this blog, I think the 8 propositions do not conclude, as Carrier thinks, in "nothing would give rise to anything, including everything we know, even without God", but in "nothing would give rise to anything, including everything we know, even without God unless God is the necessary being".

He thinks that even though he has all along admitted that whatever it is necessary to exist must exist, both because it must and for this to result, this still excludes God ... from being that necessary being.

Now, I was a bit sloppy in responding a few days ago, and missed a nuance or two in one of his responses.

Here it is:

Wow. I can't believe you are this dense. "Gravity explains the motion of the planets." "Maybe it doesn't, because angels do it. It's possible! Therefore you cannot conclude gravity causes it." "We have logically demonstrated that 1+1=2." "Maybe some hypothetical future logical demonstration will prove 1+1 doesn't = 2. It's possible! Therefore you cannot conclude it has been logically demonstrated or even that it's true that 1+1=2!" "Fermat's Last Theorem has been formally proven." "Maybe there is an error in the proof, some logically necessary fact we don't yet know about that entails the theorem is false. It's possible! Therefore Fermat's Last Theorem has not been formally proven and we shouldn't believe it's true." And on and on. This is how you are arguing. It's the stupidest argument on the planet. Because it entails you should deny all knowledge, because "maybe" some unknown fact refutes it. It displays total ignorance of how logic works, how probability works, how knowledge works, and how sanity works.


As with God being the necessary being, so also angels moving planets is one of the historically available options on the palette.

As long as you don't exclude it, positively, like by saying explicitly "angels don't exist" (which atheists can and Christians can't) you cannot exclude that gravity is a non-explanation OR incomplete explanation of planetary movements.

Obviously, this is sth quite other than appealing to a very tenuous potentiality of a future demonstration 1+1 NOT = 2 or Fermats Last Theorem to be disproven.

As to Fermat's Last Theorem, I am for the moment agnostic, but may be more positive once I have reviewed the apt video on Numberphile or some other math channel on youtube.

But as to 1+1=2, it is the very definition of 2. Precisely as 1+2 is the very definition of 3. And so on.

You cannot disprove a basic definition.

You also cannot disprove a conclusion which follows syllogistically from such, like 2 + 2 = 4.

2 = 1 + 1 (definition)
Therefore + 2 = + 1 + 1 (transitivity of + function)
Therefore 2 + 2 = 2 + 1 + 1
But 2 + 1 = 3 (definition)
Therefore 2 + 1 + 1 = 3 + 1
Therefore 2 + 2 = 3 + 1
But 3 + 1 = 4 (definition)
Therefore 2 + 2 = 4. QED

Here each step has been explicitly argued. I have not counted on omitting sth which could be there.

I have not said "we have 2 + 2" (before my eyes) when I could be wrong and there could be 2 or 4 more hidden (under a table or behind my back). I have not counted on omitting any proposed solutions to a problem.

But if you argue that gravity and inertia explain (exclusive of alternative or complementing explanations) planetary motions from the masses of themselves and of the star they orbit and from initial conditions, and from that, that geocentrism must be wrong, you have omitted that angels could explain planetary and solar motions around the Zodiac (itself in daily motion around earth, a motion explainable by God), and you have omitted that they could explain part of the motions (like a bikers nudges explains part of the bike's motions, while inertia and gravity explain and weight of biker and surface under bike explain a lot of them). Such an omission means you have not demonstrated what you claim to have demonstrated, that "gravitation [and inertia] adequately and correctly explains planetary motions, which means we have to ditch geocentrism, despite its being prima facie empiric".

The best you have is, "if we ditch geocentrism, we can explain daily and periodical motions without God or angels", to which I counter, "if we accept God and angels, we can accept geocentrism, which is good since it is prima facie empiric".

And if you omit to show that God is not involved as the necessary being in your premises, you have also not shown that nothing would give rise to anything without God, you have only shown that nothing would give rise to anything under the circumstances of being only relatively nothing and involving existence of logically necessary existance. Which, as long as you have not excluded that, could be God.

If you like, it could be Dr. Who, as long as you have not excluded that. So, let's exclude Dr. Who from being so.

Dr. Who according to the televised series is actually suffering a few death threats (I have gathered). But the necessary being as such cannot cease to exist nor start to exist. Therefore, Dr. Who cannot be the necessary being as such. If you were claiming he could be an incarnation of the necessary being, I think you know there is a better candidate for that. You have spent books on arguing against that, right?

Done. Dr. Who is not the necessary being.

YOUR TURN, for excluding God, if you can!
