"So, I use Occam's Razor. It's just adding an extra layer of complexity to what we know, and there is no real evidence to support it. Therefore, it's invalid."

Therefore it's -more likely- to be invalid. Occam's Razor is useful, but it is not foolproof.

The way I understand to use this principle is to not introduce extra complexity into an explanation when there is no evidence to support it.

The principle as I understand it is to not introduce more complexity than is neccesary to explain a hypothesis. The difference is subtle, I will grant, but it is there. Although it's not the basis of my argument against it's use in this case.

Most theists who will actually think about why they believe in god(s) (as opposed to blindly accepting it), will say that it would be impossible to conclusively prove or disprove the existance of said god(s). I also think that it would be quite impossible to prove either way.

On this point the three of us are in total agreement. (You, me and Occam. )

Here's where I think your use of the principle fails. You have already stated you believe that the exsistnace of God to be unprovable, and by applying the razor you say the lack of proof means that God does not exsist. That seems to me to be very circular logic at best. And it also assumes that everything is "knowable" by us, an assumption which I do not accept, although I cannot refute, and which you cannot support. Only time will tell I suppose on that point.

And the issue of this thread has not been been whether or not God exsists, a point which we both agree cannot be proven or disproven here. It has been mainly "Do you really know what you think you know?". If some of the accepted assumptions that seem to support the origin of species by natural selection are incorrect it by no means proves the exsistance of a creator. But adhering to the belief in evolution regardless demonstrates the same level of faith ascribed to those that believe in the origin of species by act of creation.

An absence of evidence is not evidence of absence.

(Wish I knew who originally said that.)

Especially when you can't even get an agreement on what constitutes "evidence".

I thought we were discussing the complexity of life and/or the universe, not the complexity of proving the existance/nonexistance of a god-being. Depending on which issue we are discussing, Occam's shaving device will give (IMHO) very different results.

i) The arguement for a non-chance (most commonly a design argument) derived universe states that the universe is far (ie 10^40 or more) too complex to have come about by chance, so the easiest (Occam's razor) explanation is that it did not arise by chance. Therefore I believe that given current understanding of the complexity of the universe, Occam comes down on the side of "probability has to jump through too many hoops to be likely".

i.a) I'm not a astrophysicist however, so really, my opinion is only valid within the realm of molecular biology. It is my opinion that Occam's razor would dis-favor probability there as well. However Occams is NOT fool-proof as noted in an earlier posting... it simply tells the politicians were they should place their science funding

ii) The arguments to date for the existance of a deity or equivalent (and here I mean independantly of the above discussion of chance and the universe or the separate one on life) suggests that most if not all evidence(s) can be used for either side of the argument. That is to say, there is no complelling evidence for a diety, and so Occam's razor would suggest that all things being equal, don't introduce a diety because that's another level of complexity.

iii) where can one get some Occam's aftershave? I think I've got a little Occam's burn here on my pre-frontal cortex...

On a side note, I had (and in fact, still have) a few days before I have to take finals...

Well it sounds like your brain has warmed up quite well in this thread. I hope you do well on your exams!! What are you studying anyway?

And Candide by Francois-Marie Arouet (A.K.A. Voltaire). The final message of the text I find I agree with... basically, "We'll all be much better off if we stop spending so much time on metaphysico-theologo-cosmolonigology".

Hmmm... but it's the statement of a satisfied, well fed, man of letters, secure in his upper-class position during the peak of his civilizations' power. Perhaps a man, woman or child in Burkino-Faso would hope that there is a greater meaning to life as their family barely scrapes by on 30 cents a day?

And now to prove that I'm one of those typical north american hypocrites, I'm going out with friends to drop $13 (+popcorn) on a Star Trek Movie , night all.

Fyron: I think some of the miscommunication comes from what I read of Hume's arguments. Of course, I just picked the first link I found.

I think we'll just have to agree to disagree here. I accept that any analogy is an imperfect representation; but since there is no perfect analogy, we have to use what there is. Otherwise, we have to throw out any philosophy built on analogy. I also agree that the design argument doesn't prove the identity, number, or purpose of the designer.

Hume's argument that nature naturally produces order supports both sides. If you already believe in a designer, then design happening in nature is further proof of that design. If you don't believe in one, it's further proof that one is not needed.

Further arguments about evil in the world do not contradict the design argument. They fit into the "Since there's design, who designed it?" debates.

I'm sure I had more to say, but I can't remember without checking the thread again.

Oh, yeah. Voltaire should have spent a little less of his life philosophizing, then. "Now that I've said all I'd like to say, then I have just one Last thing to say before you answer me: Let's all just go home and catch some ZZZs, and get a real job in the morning."

The precise definition of "naturally" needs to be nailed down, I think.

I read "naturally" to be "without outside help".
