I never said God causes himself--rather, my point was that God is eternal and does not need to be caused.
You said: "God's omnipotence is such that God does not need to be caused himself". How else am I supposed to interpret this statement?
Anyway, eternity is of no help here: you can very well abstract out the whole timeline as a single entity, and ask what caused it to exist. Think of it this way: you can take a 3D universe of infinite extent, and wonder what caused it to exist. And similarly, you can take a 4D universe of infinite extent, which would include the time dimension, and wonder what caused it to exist, within the frame of reference of a second time dimension. The bottom line is that an eternal being
can be caused in a meaningful sense. No matter how you slice it, you can always build the set of "everything", and ask what caused this set to exist.
My take on this whole mess is that there is no metaphysical necessity for
anything to be caused. It doesn't matter whether X is eternal or not. The nature of a thing implies nothing whatsoever about the existence of a causation chain leading to it. An apple is an apple, regardless of how it came to be.
At the core, it's a matter of logical necessity that something must be uncaused, and I frankly don't see any restrictions on whatever that thing would be.
Hence, there is no circular justification, in this regard, for God's existence. He simply "is" as a product of his nature.
Now you're just serving me Anselm's ontological argument. God exists because it is in his nature to exist. But that's absurd. The nature of a thing entails nothing about its existence.
And I maintain that the uncaused causer is incoherent in terms of human grasping. Simply because you can describe the notion in such a way that the gist can be apprehended, it does not follow that you can wrap your mind around the conceivability of such an eternal being.
But that's the thing. I
can wrap my mind around it. If you have trouble grasping the concept of an "uncaused causer", it is because you have a very strong intuition about the universality of causality, strong enough that the concept of an "uncaused causer" seems wrong, incoherent to you. I know the feeling, because I've had it before. But I've thought about it a lot, and I've eventually concluded that my intuitions were out of whack. And as I realized this, they slowly shifted. Now, my intuition about causality is extremely weak: I don't see a necessity for anything to have a cause. Therefore, the concept of an "uncaused causer" does not cause any cognitive dissonance in my mind.
From my experience, I can tell you the following: our intuitions about the world tend to be much stronger than they should be. Therefore, as soon as one enters the realm of metaphysics, one should expect a lot of cognitive dissonance: what is "outside" the universe? What was "before" time? And so on. But the more you chip away at your intuitions to make them weaker and more malleable, the less problems you encounter. Food for thought.
Think of it this way: what makes modus ponens true?
Nothing makes it true. It's valid by definition. Modus ponens is part of the inference system upon which the concept of truth is built. Any other system would not be describing truth, it would be describing something else.
Some say, and I am inclined to agree, that what makes basic logical laws true like modus ponens is some intuitive element where, by the natural light of reason, we see how it must be true.
I have an immensely simpler take on it. Any inferential system on propositions, coupled with an initial assignment, implicitly defines a predicate. Logical laws form such an inference system. "Truth" is the name of the predicate that our observations, coupled with these laws, define. The reason why "truth" is such a prevalent concept in our minds is that it's useful. No more, no less.
I agree with deck in that we need some sort of benevolent divinity for ultimate purpose in life. not saying that i believe in a God quite yet, though. we need God for our lives to have any necessity: "making" our own purpose is a sort of delusion, as it is outside the scope of our powers to create purpose that governs with necessity. purpose needs to be mathematically necessary for it to even be purpose. it's like creating a game and saying that the game has higher purpose: it doesn't, as the game is simply the game. Making our own purpose makes that same purpose completely arbitrary, just like the goal of any particular game is totally arbitrary. something greater than us must exist. so in my opinion it's God or no purpose. not sure which side i lean on
I do not see how a deity could possibly define an ultimate purpose. I mean, of course, God could promulgate some sort of moral code and tell us to follow it, but why exactly should I care? What makes this "ultimate purpose" any more attractive than the purpose I set for myself?
Think about it this way: the purpose of a hammer is to hit nails. One might even say that this is the ultimate purpose of a hammer, as set by ourselves, their makers. But now imagine that hammers become sentient. Do you think a sentient hammer would give two shits about its "ultimate purpose" to hit nails? It would - if it enjoyed hitting nails. Otherwise, it would tell us to fuck off, and rightly so.
You speak of ultimate purpose as if it was desirable. Why is it desirable? I don't want an ultimate purpose. I want to make my own, because it is only through making my own purpose that I can achieve my own goals and satisfy my own aspirations, without the interference of some deity. Why would I want to follow God's purpose, should he exist? Either he offers me a sweet deal, or he forces my hand (with hell threats). Otherwise, I'm going to tell him to fuck off.
And it's not because God sets a purpose that it's not arbitrary. A game we make has an arbitrary goal, but so does a game made by God. Even if you specify a "benevolent" God, benevolence is an external restriction we place on him, so whatever purpose such a God would define could be "objectively" derived from the benevolence assumption. No need for deity.
Brain, I think you are misunderstanding the basis of "belief" here.
I am blatantly ripping off some quote in the Ender's game series, but when you tell your son that you "believe in him", you are not telling him that you "believe he exists."
Belief in God (at least in Christianity) is not belief in existance, but instead more along the lines of faith you have in your loved ones and people important in your life.
You don't "know" that Jack Sanders, your ace CB and dear teammate will make the pass cut and take your high school football team to the state championship. But in those moments in the last minute of the last quarter, as the pass flies through the air, you "believe". Your belief could very well be wrong, but "trying to not be wrong"--that's not the point in your belief.
Really, even if Jack fails and the opposing team makes the pass, that still does not remove the purpose of your "belief."
I do not misunderstand the basis of belief. The passage you quoted was me describing how
my own belief system works. I simply do not "believe" in the sense you describe. I really do almost always try to not be wrong. I do not "believe" as the pass flies through the air. I "hope". I do not "believe in" anyone without good reason, even when I tell them I do. I "hope" they will succeed. Being careful about the expected accuracy of my beliefs is like second nature to me.
The rest of my post, however, was meant to address how the belief systems of religious people, as evidenced by several posts in this thread, works. I'm not sure whether you actually read or understood what I wrote, or whether what I wrote was clear enough, but I don't see where I made a mistake. Your response is perfectly coherent with how I assessed religious belief. In fact, it vindicates it. So color me confused.
