It also does not state that any "first cause" must have any type of life or intelligence. It could be totally mechanistic.
It could not be.

Let us assume that you are correct, and that an impersonal, mechanistic first cause set off the Big Bang. Being impersonal, it changes only as the result of another force. It cannot "decide" at any one point in time to explode, for instance.

A rough example. Imagine a Second World War bomb is jettisoned into space, beyond the galaxies and stars. It is in the blackest and most distant reaches of space where even encountering a stray atom is so wildly improbable it never occurs. If that bomb is in a state of total equilibrium so that its atomic structure is stable and its components suspended from any and all forces, and if that bomb does not explode for hundreds of billions of years, we must conclude that it never will.

On the other hand, if it does explode after hundreds of billions of years, we must conclude - since it follows with inevitable logic - that something has changed the total equilibrium of the unit, and thus interfered with its stability. In other words, once something begins, it must have a cause. A cause beyond itself.

In the case of the universe, the cause cannot be a mechanistic or impersonal force,
since the Big Bang created time, space and matter including all the forces that work on matter. Whatever triggered the Big Bang must therefore be beyond space, time and matter (the universe is the equivalent of my bomb analogy) and must have the capacity to begin a process. An impersonal force has no capacity to begin or to cease acting. It acts constantly and consistently.

Since scientists concede that the cosmic singularity that expanded in the Big Bang was stable for at least some of "time" prior to the Big Bang, anything that destablised it - something beyond space, time and matter - must have the capacity to begin a process. By definition a personal actor.

But, this is an hypothetical aside anyway since the premise is speculative. We are talking about "forces" acting in an "environment" in which there is no time, no space, and no matter.

OK, so what makes you so sure that this mechanistic creator of our universe did not also create other universes? Maybe that's what it does - crank out one universe after another, mindlessly. It could have been doing this for all eternity.

What kind of impersonal force could do this? We know that empty space is not really empty, but consists of virtual particles popping in and out of existence. There is absolutely no reason why our universe could be a virtual particle on a vastly larger scale.

It is very possible that outside of our universe there is an endless sea of universes popping in and out of existence.

3. The earliest Christians died for their beliefs.
I list this because I see it so frequently, but it is a poor argument. 9/11 terrorists died for their beliefs as well. It WOULD mean something if Peter of James died for their beliefs, but there's no direct evidence that they did (just legends).
If the argument was that "Christians died for their beliefs therefore their beliefs are true", then it would render Christian philosophers among the most stupid practitioners of their craft in human history. Self-evidently people die for a lot of things: their country, their woman, their god, their politics. The many thousands of German S.S. officers who battled in Berlin to their last breath do not render NAZI theories of Aryan racial ability any more true than if they had not died.

But, of course, this is not the Christian argument. It is a misrepresentation of it. The Christian argument - by knowledgeable and good apologists - is: the early Christians would not knowingly and willingly have suffered and died for a lie. It is an indisputable truism that people seldom die for anything flippantly. Thus this argument tends to be used in an historical context to counter the claims of bias on the part of the early Christians.
4. The rapid growth of Christianity can only be explained by a miracle.
Another poor argument. Christianity grew about as fast as the LDS church. A pretty good clip, but hardly miraculous. It REALLY took off after the emperor became a Christian.
I have never heard this argument. I think this is another misrepresentation of the actual apologetic argument: Christianity should not have been able to grow and spread like it did under the kinds of state and religious persecution it experienced. The effort to make the apologetic argument "Christianity grew therefore it is true" would once again imply that Christians were illogical, or their philosophers imbeciles. That is not what good apologists argue.

The analogy to the LDS church is a fallacious one. Joseph Smith died in a gun-battle. This was seen as a heroic death not at all analogous to the "scandal of the cross" (Gal. 5:11). If Jesus had died in a sword fight, then Smith might indeed be a good analogy to use on that score.

And while it is true that the LDS church was persecuted at its inception, and its members (and some of its leaders) killed, the persecution did not last for more than two hundred years, and was not a savage state persecution that saw its members being set on fire or fed to animals.

The Liber Pontificalis, for instance, describes the Diocletian persecutions killing 17,000 Christians in a thirty day period alone. You would not get even a fifth of that for Mormonism over their entire course of their persecution.

So the analogy is a bad one. If you can find an ancient sect subject to centuries of sporadic violence and persecution, which nevertheless flourished in spite of its Leader and His friends being murdered, it would be a far better comparison.
5. The Gospels provide evidence that Jesus rose from the dead.
Nonsensical. The Gospels were written by believers for believers to support their beliefs. They are not news reports. Fundamentalists try to add credence by insisting the Gospels are eyewitness accounts - but these assumptions are not supported by the evidence.
Again, not the argument. The argument made by good Christian apologists is that when the gospels are treated like historical sources (which they are), they provide testimony to the resurrection that is at least as good, and more often better, than the testimony for any other ancient event. The argument is not, "there is a document therefore our beliefs are true".

The rebuttal that the Gospels were written by believers for believers is a truism. Of course they were. But it does not logically follow that a text written by one believer to another believer is false. That is a fallacy. And if the fallacy were true, then we would have to discount much of the limited ancient documents we possess which are considered to provide good testimony to events generally held to be true.

The idea that news reports are more likely to be true than biographies is begging the question. And what "evidence" exists to show they are not eyewitness accounts? That is again begging the question that we posses hard evidence that shows that the authors of the gospels were not eyewitnesses. Really? Where is this evidence? And how does an historian identify with such absolute certainty the authorship of a document thousands of years after it has been written? Please enlighten us with your historical methodology for it would advance the field many light years! Of course this claim is utterly bogus.
6. Because the Christian faith is based on belief in the Resurrection, it must be true.
Fallacious. I agree that belief in the Resurrection is a core belief of Christians. However, the possession of a belief is not indicative of truth; it just means people believed it and spread this belief.
Again, not the Christian argument. Good Christian apologists might argue that the Resurrection, if true, proves the Christian faith, but I know of no good apologists (and I follow the field closely) that would argue that merely because one believes in a resurrection, therefore the belief is true. That is self-evidently absurd.

As I said previously, when one cannot even bring themselves to represent what the other side says accurately, fairly, and meaningfully, it means that one never has to engage with the argument. Straw men work that way.

And, further: if one prefers to engage with the worst that one side has to offer rather than their best arguments, it seems to me to be a tacit acknowledgement that we are content to be what I call a low altitude flyer on intellectual matters.

Not one of the Christians who willingly suffered and died for Christianity saw Jesus both before and after he died. They died for a belief that they got from others, just as the 9-11 hijackers did.

In that case they are on very shaky ground. We don't have a reliable way to know which events recorded in ancient times are accurate, which are distorted, and which are simply made up. This is even true of events long after Jesus. Did King Arthur really exist? Was there really a Knights of the Round Table? What about Robin Hood? We just don't know.

Are you reading what I write? I am not "sure" about a mechanistic creator, because the post to which you responded contained my explicit rejection of that concept. Instead, I provided some reasons for thinking that anything setting off the Big Bang could be personal, not impersonal and mechanistic. I observe you interacted with nothing that I wrote, and simply repeated an assertion.

The various theories behind the concept of a multiverse, or quantum universes, does not generally propose separate universes as you imagine, but an interconnection of universes, much like the branches off a tree. Or a sequence of bubbles. Even parallel dimensions are usually conceived of having been joined together at some point.

The problem with your idea is that you are proposing a mechanism that lies beyond space, time, matter and energy, which defies the scientific method, and which produces not merely one universe - as the Christian Yahweh is said to have - but endless sequences of unknown universes! Yet this is presented as a more likely hypothesis.
What kind of impersonal force could do this?
Force is not a very accurate term here. A "force" is a physical function and therefore can only occur in an environment containing physical elements. Your impersonal originator of multiple universes exists outside (and beyond) space, time, matter and energy. Therefore, let us simply call it X.

What kind of impersonal X could do this? Good question!
We know that empty space is not really empty, but consists of virtual particles popping in and out of existence.
We do not "know" any such thing. Virtual particles are part of what is called a quantum probability calculation. They were invented by physicists to explain the intermediate stages of Feynman diagrams. There is no point in arguing - as your magazine article attempts to do - whether they are real or not since they cannot be observed. Any effort to observe them necessarily impacts, and changes, the particle processes being conducted.
There is absolutely no reason why our universe could be a virtual particle on a vastly larger scale.
What a shame it is that we cannot amalgamate disparate pieces of knowledge and string them together into a just-so story. For, I could just as easily propose that there is "no reason" (none - other than the total absence of positive evidence) for why our universe could not be a huge, virtual pancake cooking eternally on the virtual red-hot shell of an enormous, virtual cosmic turtle that swims about in a virtual vat of excreta.

Your argument is a fallacious appeal to silence. There are no end of non-existent reasons for why proposition Y is not true. Yet, what is supposed to matter to an intelligent sceptic are the existent reasons for why proposition Y is true.
It is very possible that outside of our universe there is an endless sea of universes popping in and out of existence.
Some people argue with more evidence (surprisingly) than you have marshaled above, that it is "very possible" that extra-terrestrials exist, but I do not believe that proposition to be true either. Possibilities are not probabilities.

The article describes precisely how they were observed:
Are virtual particles really constantly popping in and out of existence? Or are they merely a mathematical bookkeeping device for quantum mechanics?

Gordon Kane, director of the Michigan Center for Theoretical Physics at the University of Michigan at Ann Arbor, provides this answer.

Virtual particles are indeed real particles. Quantum theory predicts that every particle spends some time as a combination of other particles in all possible ways. These predictions are very well understood and tested.
The article describes some of the tests and concludes with:
Thus virtual particles are indeed real and have observable effects that physicists have devised ways of measuring. Their properties and consequences are well established and well understood consequences of quantum mechanics.

Even your article tacitly acknowledges the alternative view, that virtual particles could perhaps be a "mathematical bookkeeping device". In fact, your article is a very good reason for the need to be somewhat sceptical when it comes to popular science magazines which often give the illusion of being a deposit of indisputable scientific knowledge.

Here is an explanation about virtual particles from the University of Vienna's website (http://www.mat.univie.ac.at/~neum/physf ... cs/virtual)

Virtual particles are part of the imagery of quantum field theory.
They are figurative language for abstract mathematics, used by experts
and laymen as imagery for giving abstract recipes for calculating
scattering amplitudes an appearance of intuitive meaning.
However, any attempt to take this language literally gives a very
misleading and unscientific view of the microscopic world.

The virtual particle imagery stems from the 1940s and 1950s when people
tried to understand how quantum electrodynamics and its generalizations
can make sense. For the experts of today, the term is fully exchangable
with ''internal lines in a Feynman diagram'', without any intended
meaning beyond that.

The collection of Feynman diagrams without loops describes _exactly_
the scattering of classical fields in a perturbation theoretic
treatment; the diagrams with k loops describe quantum corrections of
order O(hbar^k).
If virtual particles had a meaning, then they would already exist
in classical field theory, since tree diagrams have internal lines.
But nobody ever claimed that predictions of classical field theories
are caused by virtual particles.


And here is a statement from the University of Stanford's website:
(http://www2.slac.stanford.edu/vvc/theory/virtual.html)

I find it ironic that you are willing to understand a complex concept on the basis of merely a single source - and a popular one at that. This is the very same intellectual behaviour theists are often charged with by sceptics.

Note your article reads:

Virtual particles are indeed real particles. Quantum theory predicts that every particle spends some time as a combination of other particles in all possible ways. These predictions are very well understood and tested.

It is true that virtual particles are predicted as the intermediate state between an initial and a final particle. But they are not the direct result of observation. Indeed, professional physicists seem to avoid arguing whether they are "real" or not. As well they might, for anything that pops in and out of our universe does not hold the properties of "real" as is generally understood. It largely depends on what is defined as "real".
Thus virtual particles are indeed real and have observable effects that physicists have devised ways of measuring. Their properties and consequences are well established and well understood consequences of quantum mechanics.
That is certainly the conclusion of the article - which seems to spend a substantial portion of its thesis in defending the existence of sub-atomic particles, which are of course real - and I agree that it presents the impression of settled science.

Yet this is presented as a more likely hypothesis.
Point out to where that proposition "defies" the scientific method. At best, it "defies" some current theories about space, time, matter, and energy. And really all you are doing is pulling a double standard by proposing that there is a "personal being" that lies beyond space and time.

You've got a long way to go before proving that cosmological argument as sound. Especially if "willful cause" is basically deterministic, in which case saying that the first cause was "personal vs. mechanistic" is completely unintelligible.

It is not necessary to contend that "early Christians died for a lie". They may well have died for stupidity or gullibility (my opinion). They may have actually believed the tales of "miracles" and "resurrections" and "divinity" (and talking donkeys) that they were TOLD by religion promoters (people, such as Paul / Saul, who cannot be shown to have witnessed what they wrote about)

How is that different from Japanese soldiers dying in WWII believing that Hirohito was a "god"? They may have believe it -- SO WHAT?

Dying for beliefs is no assurance that the beliefs are true. Humans are often easily misled by "false prophets" (and "gods" and "godmen" and "demons") -- evidently.

Some modern Christians still believe those tales (and may be willing to endure difficulty or death for their beliefs). Does assure that the beliefs and stories are TRUE?

Yes, and it has statements like this:
Re: How "Real" Are Virtual Particles?

--------------------------------------------------------------------------------

From what I have read about virtual particles, the Lamb shift is a direct measurement of the effect of virtual particles on the hydrogen atom. So yes they do exist.
But I am by no means an expert on this subject. There are other interactions that require virtual particles to exist such as the Coulomb Force, Weak and Strong Nuclear Forces,
and the Casimir effect to name a few. The key to understanding virtual particles is that there existence is limited by an extremely small time and space but they do leave evidence of their existence.
The fact that they leave evidence of their existence has always bothered me because of the law of conservation but I guess the way they get around this is that they leave a +1 effect and a -1 effect that eventually cancel each other out.
CalvinsBulldog wrote: And here is a statement from the University of Stanford's website:
(http://www2.slac.stanford.edu/vvc/theory/virtual.html)
Which says:
We picture the quantum vacuum as a
fluctuating sea of virtual particles; the virtual particles cannot normally be directly
observed without violating energy conservation. But near the surface of a black
hole the effective potential energy can negate the rest energy of a particle and
give it zero total energy, and the surface itself is a one-way membrane which can
swallow particles so that they are henceforth not observable from outside. The
net effect is that for a pair of photons one photon may be absorbed by the black
hole with effective negative energy -E, and the other may be emitted to
asymptotic distances with positive energy +E. The characteristic energy E of the
emitted photons may be estimated from the standard uncertainty principle.

Quantum mechanics is one of those subjects where I read everything I can get my hands on, and I have been doing this since Isaac Asimov was alive. That was simply the first reliable scientific (as opposed to sites like Wikipedia) source I got from a Google search. Scientific American is also a pretty good source.

This is probably where the discrepancies in what I have been reading are coming from - differing opinions as to what is "real".

I define as "real" anything that has observable effects, and virtual particles have observable effects. Because of them black holes evaporate, which is good because they could very well be created in our sun all the time, and we wouldn't want our sun (and all the stars) falling in to them. (No worries, they don't last long enough.) They also produce the Lamb effect and the other effects mentioned in the articles. So, they are "real" enough for me.

It is also worth pointing out that our best measurements of the universe so far show that there is just enough dark matter and dark energy in our universe to exactly cancel out the physical matter, so that the universe adds up to exactly nothing. So, maybe in some absolute sense the universe is not real. But, it is "real" enough for me.

I have got to say that you understand this better than any theist I have known.
