26565, RE: What the hell?!

First of all, let me apologize for taking so long to reply. I've been distracted by my work. I guess we're even on that count now.

Okay, then when you said

"If I say there is a God, and you say there is no God, one of us is wrong. This is the first rule in logical truth-value."

citing the bivalent truth table, you were just being sloppy?

Sure enough. I'm not trying to criticise that premise (even if it deserves some criticism, from a political standpoint).

This is a standard classical perspective, but it is simply not true, once you look close enough.

A quantum superposition of the states |existence> and |nonexistence>. For example, if the one-particle state in some Fock space is labeled |1>, and the Minkowski vacuum is labeled |0>, then one can prepare a system in the state

|psi> = alpha |0> + beta |1>, where |alpha|^2 + |beta|^2 = 1.

Once this state is prepared, the particle both "exists," and "doesn't exist." The probability of measuring it existing is |beta|^2, while that of measuring it not existing is |alpha|^2. You can point out that after such a measurement, it did one or the other, and argue (in the classicist tradition) that it was actually in one state or the other even before the measurement; that our probabilistic description is not primitive, but rather a result of our ignorance of the system. However, this is not true. In a seminal paper, Einstein, Podolsky and Rosen showed that this assumption has measurable, statistical consequences, and the resulting "quantum entanglement" measurements showed beyond any scientific doubt that objects do not take on an objective reality when they are not being directly observed.

I'm very honored by the suggestion, but Schrodinger already won a Nobel prize for this, in 1933.

Okay. That's all I was getting at.

I had no doubt that you were familiar with the Pythagorean theorem. There's a reason I chose to cite the most famous theorem in the history of mathematics. If I wanted the history to go over your head, I would have cited the Morse index theorem, or the Gauss-Bonnet-Chern theorem.

The problem (and again, this is completely irrelevant to the present discussion) was your statement that "numbers" were needed for its proof. Open Euclid again (or Google it again, if that's what you did), and look now at the proof. You will not see any numbers. Go through all thirteen books, and you will not see a single number (aside from those labeling the propositions, definitions and axioms). Even when he was building the foundations of number theory, he was working with purely geometrical structures.

You're the one who's making particular premises about the nature of existence. I'm only here to argue that we should all be ready to rethink our dogmas.

Okay, but I'll remind you that they are not only relevant, but apparently necessary, in describing the natural world (even "existence" in the natural world). This point is not relevant to the supernatural world (whatever that is), but the hard work it took for us to accept it reminds us that sometimes our premises are naive.

Just like Newton knew his corpuscles either did or did not exist.

Ahh. So there ARE things which didn't "come from" other things. If it's so easy for you to accept that God "simply is," why can't you say that the world "simply is"?

Well, they are relevant (and necessary) when describing the existence of physical objects. But I was wrong: for that discussion, you'll probably need a Quantum Mechanics book, not a logic book. I recommend Isham.

That was a goofball comment on my part. I'd apologize, but the statement did more harm to my argument than it did to yours.

True, ordinary photons do conserve energy. But virtual photons do not. That's why they're called "virtual" photons. They are allowed this nonconservation because the definiteness of their existence is limited under restrictions placed by causality.

Don't argue with me on this. I'm writing right now from an office down the hall from the one Stephen Hawking uses every year when he visits my research group. I don't drop that name to brag, only to point out that I really do know what I'm talking about. If I ever want to argue with you about Christian doctrine, I'll be sure to read that Bible first. If you want to argue with me about particle physics, you'll probably want to read Weinberg first.

No, they do not just "exist." Their nature is always a quantum superposition of existence and nonexistence. This superposition is a necessary consequence of their nonconservation of energy.

Tell that to them, not me. Personally, I don't really care to read the Bible "in context." It doesn't interest me any more than Weinberg interests you. This Bible just looks like a bunch of silly culture. It looks no more holy to me than the Koran or the I Ching do to you. If I don't care to follow your doctrine, then I can only judge it by judging those people who claim to be adherents. If you want to make the Christians of the world look respectable, you have a lot of work to do.

Neither. The biggest threat to Christianity is ordinary, level-headed thinking; the recognition that the edifice of Christianity, like all religions, is built on the foundation of a particular culture -- one which is quickly disappearing.
