Re: William Lane Craig and Kevin Scharp | Is There Evidence for God?

Of all the laws from present science, I like fine-tuning the most, but to say that I like something the most from a class of arguments I don't particularly care for, isn't to say much in its favor.

Before we address Kevin's particular work up of the argument, does anybody here in particular find the fine-tuning argument ultimately compelling? I myself am not even particularly convinced that it can get you to a transcendent level, let alone to God.

Thanks, that's helpful. Let's look at versions of the cosmological argument that depend on principles of causation.

The problem is that armchair reasoning about causation is completely unreliable because cause and effect are two very old and imprecise concepts. Our intuitions about them can easily be led astray; for example, that causation is transitive—if a causes b and b causes c then a causes c. But it’s easy to come up with counterexamples to this—a hiker sees a boulder bouncing toward her and ducks to avoid it. The threat of the boulder caused her to duck and her ducking caused her to survive but the threat of the boulder didn’t cause her to survive. Moreover, there are other principles about causation that seem to go against this argument—causes are governed by natural laws, causes and effects are events, causes precede their effects. None of these is compatible with God’s agency causing the universe.

Trying to uncritically use the concepts of cause and effect in the context of general relativity and quantum field theory would be like if Aristotle were transported to a contemporary chemistry conference and complained that fire isn’t on the periodic table.  “Don’t you believe in fire?” “Yes, we do, but we just don’t think it’s fundamental any more.”


Causation is not a conceptual tool of advanced scientific theories. For example, in the statement of Quantum Mechanics, the word ‘cause’ doesn't appear at all, nor does it in the statement of general relativity. Instead, what you have is a complicated mathematical structure (e.g., an infinite dimensional, separable, Hilbert space that has inner products—this is a particular kind of object commonly studied in the branch of mathematics called abstract algebra, one studies it typically as an advanced undergraduate in math or physics) and a way of interpreting it (e.g., various things that can be measured are associated with different aspects of the mathematical structure—e.g., time as an self-adjoint operator on the space). General relativity works the same way by applying tensor fields—a kind of mathematical structure studied in differential geometry, one studies it typically as a new graduate student in math or physics. Very roughly, scientists observe the world, feed their measurements into a mathematical model, use the model to calculate predictions and then try to test those predictions. Using the concept of causation need not come into it. Notice—I didn’t say that it cannot come into it, so when Craig throws together a bunch of quotes of scientists (usually in popularizations of course) using the word ‘cause’, that will be totally irrelevant. He’s going to do it if he ever bothers to respond to this objection because that’s his number one research tool, and now you know that it will be just as illicit this time as it always is. Instead, the point is that the concept of causation is dispensable in mature sciences that rely heavily on mathematical models. Using causes to make predictions turns out to be vastly less precise than using mathematical models. Remember, causal concepts by themselves provide much in the way of understanding or predictive power. Cause and effect aren’t scientific concepts. Moreover, causation isn’t just dispensable, it’s easy to show that using it all to reason about certain aspects of scientific theories leads one into contradictions. Causation, it turns out is part of a way of thinking about the world that dominated for a long time, but is now slowly being replaced by much more precise ways of thinking about the world. So any time Craig makes point using the concept of causation, he needs to stop and first provide a detailed justification for thinking that causation is even the right concept to be using here. That would be tantamount to justifying the claim that our world is a world governed completely by the principle of cause and effect. Check out John Norton’s paper “Causation as Folk Science,”—it’s free and it does a good job of summarizing and defending this point.
 
WLC Cause Example
“If a cause is sufficient to produce its effect, then if the cause is there, the effect must be there, too. For example, the cause of water’s freezing is the temperature’s being below 0 degrees Celsius. If the temperature has been below 0 degrees from eternity, then any water around would be frozen from eternity.”  This is a perfect example of the imprecision of using the concepts of cause and effect to try to reason about the existence of anything much less gods or Christianity. The cause of water’s freezing is the temperature being below 0 degrees C. If a cause is sufficient to produce its effect then if the cause is there, the effect must be there. But anyone who takes an intro to chemistry class knows that water can be below 0 degrees C and still be water. In fact you can take liquid water down below -50C if you don’t allow crystals to form. You can also experience this supercooled water in the form of freezing rain. So although you might all nod your head and say “yeah, that sounds really obvious” when asked if having a temperature below 0C is the case of water’s freezing, it isn’t true. Or maybe it is true that that’s part of a cause or whatever. The point is that causal talk is not very precise and totally inadequate for the uses of science, which is ultimately measured by predictive success. So Craig’s own example illustrates perfectly the confusion I’m talking about and this kind of confusion is rampant throughout his work.

Re: William Lane Craig and Kevin Scharp | Is There Evidence for God?

Will be storming into all of this tomorrow folks. And many thanks to Poe for that write-up,

Only one thing to add till then: for the Cosmological Argument should we look at the PSR Argument from Contingency based on the 'weak' PSR as some times employed by WLC (though that particular formulation came from Stephen Davis originally)? There's similar formulations scattered around on this forum. Alternatively someone can dig out a copy of Reasonable Faith.

Even if we grant you that causation is not a useful concept for high-level mathematical physical theories, this does not address how it might be used in biological, medical, geological, and possibly even chemical fields of scientific study; as you have argued against Craig himself, the sciences are a package deal, and unless one is a reductionist, which you are not, I cannot see why causation cannot at least be a useful concept in those other fields of study, even if it's not at the level of theoretical physics.

And even if we grant you that the sciences don't deal with cause and effect, why would that prove their unreality? Science does not deal with the abstract objects, but that doesn't mean they are therefore off the conceptual table. Heck, try writing a history book without ever speaking of causation!

Also, I find your example quite strange; why is it that water can stay unfrozen in generally unexpected way not just a sign that we were moving too fast in our generalization? Most people would grant you the premise that, say, all penguins are black and white, but that there is a non black and white penguin does not show that people are somehow conceptually confused about the color black and white.

Furthermore, please design for me an experiment that makes no use of the notion of cause and effect; even if theoritical physics need not discuss it, how exactly are we to confirm theories without causes?

Re: William Lane Craig and Kevin Scharp | Is There Evidence for God?

Also, before we get too far down the rabbit whole, are we talking about Humean causation, with its "loose and separate" view of cause and effect, it's treatment of cause and effect as two separate events, it's complete identification of cause and effect with close correlation of cause and effect in space-time, and it's complete repudiation of any talk of casual powers? **Boo!**

Or are we talking about a more Aristotelian account, which features a necessary connection between cause and effect, treats cause and effect as one event looked at from two different perspective or with two different aspects, is quite hesitant to jump from a mere correlation to causation, and can get hardly a word out without referring to casual powers? **Yeah!**

Which idea of causation we have in mind will radically change the discussion, and also how we think causation is supposed to work.

Re: William Lane Craig and Kevin Scharp | Is There Evidence for God?

I understand him to be dismissing all such notions as obsolete, imprecise, etc etc.

It's interesting always to hear a philosopher poison the well by speaking of armchair theorizing. It is a strange sort of man with a strange sort of audience who disparages himself as a means of victory.

The concept of causation is old indeed, but it is not at all imprecise. The Kramers–Kronig relations imply that in physical systems causality is logically equivalent to stating the analyticity of response functions in the closed upper half plane.

This flies in the face of modern philosophy of science. Let me put it to you like this: if causality could be "reduced" to something more fundamental, then we no longer need to replicate scientific experiments, as we could simply build equipment that detects the "particles of causality" and prove induction right then and there.

Except that it absolutely is a tool of advanced scientific theories. This statement is flat out false. The opposite of truth.

KevinScharp wrote:

However, the Kramers–Kronig relations do appear in quantum mechanics when it comes to determining the properties of any linear response function, such as that of an photon, and can even be used to calculate optical properties such as the absorption coefficient and permittivity.

KevinScharp wrote:

One of the reasons why General Relativity uses tensor fields is because tensors are invariant with respect to coordinate transformations, and it is a metaphysical (meaning the "physics of physics") requirement that the laws of physics are the same regardless of choice of coordinates. So here in General Relativity we see that metaphysical considerations are used to determine what theories are physically admissible. Causality also plays the same role here: it limits the admissible mathematical structure of the universe to that of a globally orientable Lorentzian manifold.

(1) No it isn't, as I have demonstrated before.

(2) You are setting up a false dilemma, as if causality and mathematical modeling are mutually exclusive, but in some circumstances, causality can actually be formulated in explicitly mathematical terms!
