One use these an alleged contradiction in these three principles to attack causal versions of the Cosmological Argument, but few defenders of that argument, and maybe even realists about causation as a whole would accept them. Point 2, although one WLC would be willing to endorse for the sake of the argument, would be opposed by those who hold an Agent/Substance as opposed to Event view of causation. Point 3 would be denied by virtually all defenders of the Cosmological Argument as well as others (Kant and perhaps Armstrong come to mind).

In both cases these stances are not motivated by independent metaphysical reasons and not a priori commitments to theism. In order to make the above objection stick the critic is going to have to turn his fire on these positions and their metaphysical backdrop itself.

I don't think so. You're missing my point -- I agree that defenders of cosmological arguments will tend to reject principles 1 2 and 3 as long as they realize the inconsistency. My point, however, is that these principles have the same status as the principle of causality that cosmological arguments use. They're all equally plausible and arguably constitutive of the concept of causation. And that undermines the justification for the principle of causality in cosmological arguments.
 

But neither the CA defender nor many realist causation theorists will accept they're at all plausible; in fact they will claim we have strong reasons to think them all false.
 
If you don’t mind me saying you seem to be working under the assumption that defenders of the CA will operate along the lines of WLC’s modus operandi in debates, that is to set forth a number of points as plausible e.g. acceptable to people with a wide range of differing metaphysical commitment, to which you will response that those points given above are just as plausible (at which point in a debate scenario the onus would shift to him to justify why his points are stronger).
 
That isn’t what most theistic metaphysicians, certainly not those from the older traditions, will do though. They will enter the dispute* with (according to them) strong independent reasons why their theory of causation is correct. If one wants to undermine the CA one has to challenge their arguments for the other aspects of their metaphysics e.g. their theory of causation, on which it depends.
 
*I’m using dispute as a neutral way of framing ‘debate’ in order to avoid confusion with debate as in timed debate scenarios of the kind WLC specialises in

Good -- thanks for the contrast between the Craig approach and the theistic metaphysician approach. I can see why you'd think I was presupposing the former. I'm arguing against any theory of causation that takes the concept of causation to be governed by a consistent set of rules. That means any of the theistic metaphysicians' theories of causation are my targets. From my perspective, any theory of causation you're talking about is going to pick a more or less consistent subset of the constitutive principles for the concept of causation and focus on them. So, even though the principles I listed above might be rejected as false by some, you'd need to argue that they aren't meaning-constitutive in order to avoid the point I'm making here.

However, there is a much more important point, which is that anyone who uses the principle of causality in a cosmological argument needs to justify using it there. Why think that this principle of causation can be applied in this arena?

Right, but my point was that one might be pretty certain that causation is transitive even after thinking about it for a while by considering the matter apriori -- that is by reasoning with principles that seem to be constitutive of causation. That causation is transitive is a principle like this as are principles used in the cosmological arguments (note that Craig mentioned in his most recent Defenders podcast that his confidence level in the latter is 100%). I'm saying that even if some principle is constitutive of causation, it can turn out to be false. Ex: transitivity. The principle of causality is too.

That goes for everything you're writing too. Unless you have a paper showing your arguments in computer-verifiable proof form, you're relying on intuition. Even Euclid reasoned with intuition, and it took over 1,900 years for others to figure out that the Axiom of Pasch was needed to formalize Euclidean geometry (meaning that he made a leap of logic in his proofs).

So...you're agreeing with me? The person who uses the principle of causality in a cosmological argument owes us a justification for thinking that it is applicable and even that it doesn't have any counterexamples elsewhere in similar circumstances.

Just to answer all of these together, my point is not that the theories will contain cause and effect but that the theories pre-suppose cause and effect in them. There is no need to include everything you pre-suppose in the first place to build a theory. 

As an example I will like to take something that you mentioned to Tomislav as follows.

First, Kinsler is not saying that causality is ubiquitous in physics -- in fact, he gives examples of physical theories that have no causal interpretation at all (F=ma is his example).

My physics is a little rusty (feel free to correct me if I am wrong) but F=ma shows the relationship with force(s), mass and acceleration but we could not even come to this conclusion if we did not pre-suppose cause and effect in it i.e. The force(s) are causing the mass to accelerate, which means that the relationship between force(s), mass and acceleration can only be empirically verified when there are force or forces (cause or causes) acting upon a mass whose effect is acceleration. So yes if you look at the formula as a stand alone there is no cause or effect but you need to look at what is being pre-supposed into it to see causality.

I don't accept that all science presupposes cause and effect -- that's one reason we can find putative counterexamples to cause and effect (e.g., virtual particles in quantum field theory) in some sciences (the Norton paper contains another). How are you going to argue this?

The standard interpretation is that 'F=ma' is a definition of force, not a causal relationship. Force just IS the product of mass and acceleration (look at the units). It's not that force causes mass to accelerate any more than acceleration causes mass to have force. Neither of these is right. Moreover, in the Kinsler paper, he assumes that unless a differential equation has some quantity that has a time differential in the denominator, it does not have a cause/effect interpretation at all.

And I know for a fact that you're relying on intuition because if you weren't then you would present your arguments as a computer-verifiable mathematical proof (you don't and can't), therefore you must be relying on intuition.

Aristotle defined causality as the explanation of how something comes into being. Nobody doubts that the cosmos is both an object in its own right (because it has structure) and at some point came into being. You, on the other hand, seem to be arguing that it's sometimes okay to seek an explanation of why something came into being (bicycles, lifeforms, and stars)  and sometimes it's not okay to seek an explanation of why something came into being (the cosmos, and this seems to be the only object on your list).

But it is you who has it completely backwards. The onus isn't on us to explain why causality is applicable. The onus is on you to justify your completely arbitrary and irrational partitioning of the universe of discourse into two sets (called "everything not the cosmos" on the left and "the cosmos" on the right) and saying that it's only okay to ask how objects belonging to the set on the left came into being.

The Schrodinger equation is completely deterministic. The initial conditions completely determine the evolving state of the quantum potential. If "nothing" causes the virtual particles to come into being, then the evolution of the SE can't be determined by initial conditions, meaning that the SE is not deterministic. However, this contradicts what we are given. Therefore, you must be interpreting pair-antipair creation in a bogus manner.

First of all, F = ma is only true in classical, Newtonian physics. in special relativity, F != ma, but rather, F = dp/dt. In Newtonian mechanics, these are equivalent, but in special relativity, they are not. This doesn't take away from your point, but I feel that it's nonetheless important to point out.

But why stop at F = ma? None of the laws of physics make reference to concrete physical objects. In fact, all of the laws of physics can be formulated in terms of abstract mathematical objects. So we can conclude that the existence of physical objects is just an illusion created by our intuitions and that we live in a Pythagorean style universe where only abstract mathematical objects exist.

See how stupid that sounds?

Firstly, my point was not all science presupposes cause and effect. My point is that the theories we are building presuppose cause and effect.

Secondly, for virtual particles at least we do have explanations. When physicist’s use the word nothing they do not mean philosophical nothing (a lot of ink has been spilt on this see http://edwardfeser.blogspot.ca/search?q=nothing). This means the virtual particles coming into and out of existence in a quantum vacuum does not mean that they are coming out of nothing. Quantum vacuum not only includes other virtual particles as a field but also space time exists in it (this is not nothing). In case you are wondering you can read this http://www.wall.org/~aron/blog/a-universe-from-nothing/ from a postdoctoral quantum gravity researcher in Princeton. I do not know anything about the Norton paper so I cannot comment.

My point was that there is a relationship between Force, mass and acceleration. In order to empirically verify this, we will need to cause a force whose effect would be acceleration on a mass. Lets say, if we are able to accurately measure net forces on a moving car then the acceleration in the car and the mass would be equal to the Force. One of the force in the net force would have to be the engine of the car which would be the cause of the car accelerating.

Causality is not dependent on time; cause and effect could be instantaneous but that does not mean the cause does not exist.

No that's not my point. I'm not objecting to anyone relying on intuition per se. I'm objecting to unreflective reliance on intuitions about causation. My reason is specifically that these intuitions are unreliable because the rules governing the concept of causation are inconsistent with each other.

I have no idea why you think computer-verifiable mathematical proof has anything to do with not relying on intuition. But we don't need to go down this road since your comment is based on a misunderstanding of my objection.

It is hard to know whether you're just being a bit sloppy when you say things like this or whether you just don't know the topic well. Yes, people doubt that the universe came into being -- it might be eternal, it might be finite without a beginning (think Hartle-Hawking), or it might even be necessary. Each of these views has had and continues to have advocates.

Moreover, you're mixing up causal principles (used in the Kalam) with principles of explanation (used in the Leibniz contingency argument). You need to be more careful about what you're defending.

I'm not partitioning the domain in the way you suggest -- I don't think we can just apply causal principles to anything in the universe. You're the one defending the use of causal principles in cosmological arguments. The person making the claim is the one who has the obligation to defend it. Moreover, I've already explained by we shouldn't unreflectively rely on causal principles in cosmology. So I have explained why it's problematic.

Again, it's hard to tell how well you actually know this stuff. If you do understand it, then you also know that the whole issue of quantum indeterminacy comes down to how one understands measurement and which interpretation one gives of the quantum formalism. Pointing out that the wave equation is deterministic is irrelevant.

In addition, this was just an example -- there are plenty of others: radioactive decay, proton decay, and the kinematic example in the Norton paper.

I agree 100%. I often use the concept of mass defined in Newtonian mechanics as an example of a defective concept (like causality) since it has incompatible rules governing it.

I do see how stupid that sounds. But that's not a reflection on me. I don't know what you mean that the laws don't make reference to concrete physical objects -- that's just false on the most obvious interpretation. The standard model of particle physics refers to all kinds of physical objects. And I'm not saying causation is an illusion, which would be the analogy. So I'm not committed to anything like Pythagoreanism. So your analogy is based on a misunderstanding of what I'm doing and a false assumption about theories in physics.

You're exactly right about this, and it's part of a larger rift between philosophy and physics. However, I'm not saying they come out of nothing. I'm saying they don't obey the law of causality (i.e., they have no obvious cause). I'm not saying that they are caused by nothing.

He's assuming that the cause and effect can be at the same time, but he is also presupposing that causality requires some change with respect to time (even if that change is infinitesimal -- hence his reliance on time differentials).

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

On Aquinas' Five Ways

Someone posted earlier that many on this forum are moved by the kinds of arguments found in Aquinas' "The Five Ways". So I thought I might say a bit about my take on them.  (By the way -- is there a search function? I can't find it.)

1. First mover. Everything moved is moved by something else and there is no infinite chain of movers.

I am curious about how many people find this one plausible. There are several major problems right off the bat  -- A. motion is relative to an observer, it isn't an objective feature of reality. B. some things do move themselves -- for example, a binary star system has parts that affect the motion of the whole, and irregularly shaped macro objects do this when they are the only source of gravity (the distribution of their mass in spacetime warps spacetime in a way that makes that very distribution of mass change), and it is an active area of research in physics how a particle's gravitational and electromagnetic fields impact its behavior.

2. First cause.

I've already said a bit about this one.

3. The necessary being.

It is straightforward to present consistent systems of possible worlds where there are no necessary beings. So what additional assumptions are in play here? It has to be something about contingent beings relying for their existence on necessary beings. I'm not sure what kinds of principles are involved in defending something like that. 

4. Gradations. Some properties can be predicated in different quantities (i.e., more or less). Therefore, there are maximal levels of these properties. So there is something that is maximally good, etc.

This one seems to me to be the least plausible. We know now that quantities come with different scale types. Some scales allow for comparative judgments (X is more F than Y) but not for superlative judgments (X is maximally F). Desire is an example -- in the standard theory, desire comes in degrees (so we can say that someone desires one thing more than another) but there is no maximal degree of desire (for anything you desire, you can desire something else more). Greater than and less than on the positive integers are another example.

5. Design

I've already talked a bit about fine tuning. Are the people on this forum interested in discussing other kinds of design arguments?
