'm currently having a (unfortunately slow) discussion with Bri over there, and DavoMan complained that the posts are too long. So it's difficult to tell what it polite and what is impolite.
Your right, it is basically impossible to please all people. Then I suggest we just do what we feel is right on this topic
It would be foolish to except to meet anything outside our world face to face (it wouldn't be outside our world, if that would be possible; if a god interacts with our world, or if there is an afterlife (not that I'm expecting one), it would, according to my definition, be part of our world). But if you concede that I am actually able to know something about the IPU, that seems to be sufficient. Yes, it's an analytical truth. So what we are looking for might be some kind of analytical argument.
Agreed on every count, except for the last point. You asked "what is the reason something [i.e. the universe] exists?", which, I took to mean, is looking for a synthetic truth. What good is analytic knowledge, except for describing other knowledge? It is (in my view) pointless to say "anything inside our universe exists" and then when asked why something inside our universe exists answer "because it is inside our universe". Analytic truths, when concerning the natural universe, I tend to find uncapable of quenching the humans thirst for knowledge.
But besides that, why and in what way does the simulated world follow our laws? In your example, no matter how often an apple falls down in our world, never ever will a simulated apple ever fall down in the simulated world.
It follows our physical laws because every single atom and every single bit of 'information' exists in side our made from things from our universe. The fact that inside things fall up is only apparent because, when writing the code for it, we decided to simulate this gravity in a different direction. The whole thing is a simulation (to our point of view), and so they are not real laws. Further more, it is still a law of gravity, albeit in a different direction. How about coming up with a new law that does not, in any way, arrise or get effected by any of our current laws.
I wouldn't call it a "board game". How is the rule 2/23 influenced by our laws? Maybe you are indeed missing the point; should that be the case, I suggest you return to my longer post and re-read the text below the second picture
Opps
Unlike the previous example, the physics of this world is not just the physics of our world, with some twist added. Instead, it is built from scratch. Therefore, it is no surprise that fundamental rules of our world, like the conservation of energy, don't hold in this world.
But the world is still within our world. The physical laws are still just a simulation. And these 'new' laws are still not new! Again, give me one example of a law that is not derived from or influenced by a physical law in our universe. You can't, becuase our thinking is based on these physical laws.
Shifting the claim again a bit, are we?
Nope, I just forgot to post the explanation.
you can't have observations without theory.
Nonsense. First, let me explain my "shifting claim". I said that all knowledge is based on observation, and I stand by this claim. I also said that some knowledge is only observation. Some knowledge is directly based on observation, and all knowledge is indirectly based on observation.
Now, you gave me an example of not skepticism, but dogmatism. They know for certain that they saw a unicorn today because they do not say they saw the unicorn but had a sense experience of a unicorn. This is not a skeptical point of view. And it is pretty dead, because it was quite thoroughly disproved by the skeptic community.
To distinguish our positions, I suggest we call your position "naïve skepticism", and my position "critical skepticism".
Not at all. My position is True Skepticism, which states that no true knowledge is possible, even this statement. Your position seems to be that no true knowledge is possible, except this statement, which is Conditional Skepticism. My comment that all knowledge comes from observation is an argument against dogmatism. And I still challange you to produce some knowledge that is not based on observation.
f I understand you, you allow for the possibility that something is, but doesn't exist. Right?
Yes, there could be something outside the universe, but not only does it not 'exist', we can never study it. Without knowing this 'outside' we cannot know why there is an 'inside'. If we claim to be able to do that through induction, then it won't be knowledge at all, but a guess. If we want to guess, that's all very well and good, but I assume you do not.
