A few more thoughts...
1. Clearly we can agree that when we deal with things outside of mathematics and deductive logic, then we no longer have proof. Right? right, you've already acknowledged that. So why don't we stick with saying that mathematics and deductive logic is how we determine something to be true or not? Clearly mathematics would discard the idea of whether or not you wore a hat yesterday as mathematics and deductive logic can't tell you for sure. I suspect you feel like you're saying something of value when you suggest that science discards non-scientific claims and since some claims, particularly religious ones, fall under that category that they are somehow lesser claims. But I'll point out that we discard nearly all scientific claims when we use mathematics as our standard of truth as mathematics simply doesn't deal with the physical, it only deals with the logical.
You are missing what I am saying. I am saying that there exist, to my knowledge, only two methods of evaluating claims. Neither of these two methods are able to evaluate metaphysical claims.
So: what I am looking for is another method. So far, no-one has presented me with another method. Until they do, I am stuck - I cannot evaluate metaphysical claims.
So: do you have a method whereby you evaluate metaphysical claims? If so, what is it?
2. Why do you arbitrarily suggest that without physical evidence that we should consider a claim to be provisionally false. A claim is either going to be true or false. So why would you arbitrarily pick one as the default? Without evidence you should provisionally say that you don't know if the claim is true or false, you should not pick a side and say that it's more likely to be that than the other.
I do not arbitrarily suggest one. We cannot evaluate the claim using science or logic. However, we
can examine the fact that we cannot evaluate the claim and draw conclusions from that - using science and logic.
Until you - or somebody else - suggest another method for evaluating things, I have no option but to use science and logic.
And as science rejects claims without evidence for them, and there can be no evidence of any kind for a metaphysical claim if we do not have a method of evaluating metaphysical claims, the conclusion the scientific method would have us draw is that all such claims are provisionally false - in other words, they should be considered to be false until someone presents us with a method for evaluating them.
3. You didn't explain why the truth of your claim is logically necessary. You simply said that there has to be some reason for determining truth so it must be the scientific method. Why? And how did people come by the truth before the invention of the scientific method? Does this mean we should arbitrarily throw away every claim before the scientific method was first formalized?
Um, no. I did not say that there has to be some reason for determining truth so it must be the scientific method.
What I said was: the only two methods we have for evaluating claims are logic and the scientific method. Until someone - anyone - can present me with an alternative method, those are the only two methods I can use.
In other words, I cannot use methods I do not have.
Guess what? We
have been discarding claims made prior to the development of the scientific method, although not arbitrarily - we have been testing them, if they are testable. That is why we now know things that we did not know.
Well, let's take your claim that there is no free will for example. You're making that claim. Now by your theory, I should not accept your claim unless it can be verified via the scientific method or unless it's logically necessary. So how do we test your belief via the scientific method?
We are doing it all the time. Genetics, statistical analysis, neurobiology, evolutionary science and psychology are demonstrating that we do not have free will. And so is logic.
In other words, I do not claim that free will is logically necessary or that the lack of free will is logically necessary.
However, given that they are mutually exclusive claims, if only
one of them is logically possible, the other one
must be true.
In other words, if free will is a logical impossibility, the claim, 'We have no free will,'
must be true.
I do not want to turn this into a thread on free will, so I will not bother presenting the arguments here - I have done so on many occassions. All I am showing here is that I am
not being inconsistent - the only methods I am using are logic and science.
I would offer that we can test free will scientifically by putting someone in nearly identical circumstances and asking them to pick a number. If they pick different numbers then it appears we may have come up with scientific evidence using the scientific method supporting free will.
Sorry - 'nearly identical circumstances' does not cut it.
Yes, if anything, free will is backed by the scientific method, by physical evidence, and so forth. The counter claim that free will is an illusion has to deny the physical evidence and doesn't itself offer any scientific experiments backing it's claim. So I'm not sure why you would back down on your system of belief when it comes to free will.
I am not backing down on my system of belief when it comes to free will. The evidence and arguments are on my side - and, even if they were not (for example, assume I am in error about the logical argument - it contains a flaw - and that I am in error about the science - I have not read enough) I am still using logic and the scientific method to evaluate my beliefs. I would just be using them poorly.
If you cannot choose your belief, then there's no rational reason why I should think that your belief is any more correct than mine. If we don't choose our beliefs, rather they are forced upon us, then the same nature that forces your belief also forces my belief. There would of course be different circumstances to cause the differences just as nature one day causes rain and another day causes drought. But there's no rational basis for judging nature to be correct or incorrect in either case. Because of that, I will suggest that free will is logically necessary. Hmm.. so there seems to be 2 separate lines of argument for free will (the scientific method that shows that yes people can and do act randomly and freely and the logical necessity of it required for intelligent creatures).
That is not an argument for free will - it is an argument against it. With free will, logical arguments would never convince anyone of anything - we can choose our beliefs, and so logical arguments are completely redundant. Without free will, logical arguments at least have a chance of getting through the rest of the clutter and forcing our beliefs to change.
But this argument regarding free will is besides the point - which ever of us is right, we are still both attempting to use the scientific method and logic to evaluate the claims.
This whole thread is about asking whether there is any other method for evaluating claims.
