Not disappointing at all! On the contrary, I welcome and enjoy objections to the proof. Let me attempt to defend it. You say:
I understand your argument, but aren't you begging the question when you speak of this new world as being outfitted with "all the tech and societal structures required for a Utopia"? It seems to me that in order to prove that Utopia is possible, you take the existence of Utopia (this "world outfitted for it, populated by all-knowing beings") as a precondition. In my conception, this ideal alien world would have to be subjected to the proof also. I don't think we can take the reality of the concept Utopia as equivalent to the existence of an actual alien world that has the features of a Utopia. But maybe you would distinguish a world "outfitted for Utopia" from an actual Utopia?
I don't think I'm begging the question, but I am close. I don't mean to imply the world is already a Utopia, I mean to say that the pieces necessary for it are there. I identify what pieces are necessary by appealing to the logical consistency of the concept as related to the other concepts required for actual existence (same argument I used for theoretical possibility). So, I'm not taking its existence as a precondition. Rather, I'm taking it's possibility as a precondition. If there is no theoretical possibility, then my argument falls apart.
Maybe, indeed. But if we conceive of the future as the "yet to be present", don't you think that advanced AI may guarantee the perfection of the present, but not of the "yet to be"? Do you think advanced AI might allow us to control the future, under all its shades of contingency, in such a way as to guarantee that all future states of affairs will be already perfect as they become actualised? I'm not sure, but I can't say you're wrong either. I would have to think more about this.
I don't want to go for necessity with the AI example, only possibility. I'm using it as a case counter by concievability. It is reasonably the case that AI could grant the conclusion in your argument without the premise, just to counter the argument.
I think the umf of your argument is missleading. It looks like you try to represent an inductive inference as a deductive proof (given by conclusion 7, where I pushed at). It sounds like your argument functions more like this:
1. A Utopia is a perfect world
2. A perfect world is composed of a perfect state of affairs
3. Perfect states of affairs can only be reached by regular states of affairs becoming perfect.
- this allowed me to push with a case where the perfect state of affairs, in the context of humanity, was not the progression of regular affairs.
4. So, a Utopia can only be reached by regular states of affairs becoming perfect.
5. The world has imperfect states of affairs
6. So, the world is currently not a Utopia.
Now here, I think you're argument can go two ways. The first is weak, and is where I pushed with my second point on 7, but I think I just grasped your second direction.
7a. The world has been attempting to approach perfection, and has failed to do so
8a. If so, then the world could never reach perfection
- You might justify this by saying something like, the world has not been getting closer to being a Utopia, so there is no trajectory to suggest it is possible. Or you might say the world is asymptotically approaching perfection (harder to establish, but I might be sympathetic to that).
9a. So, the world could never reach perfection (Utopia)
Alternatively,
7b. The world continually introduces new non-perfect states.
8b. These states must all approach perfection from their non-perfect starting point
9b. If so, then there will always be at least one non-perfect state
10b. So, the world could never reach perfection (Utopia)
- argument by contradiction in premise 2
However, for this second one to work, I need to better understand how 9b works. Are these new non-perfect states introduced as discrete elements? If so, what is the rate they are introduced? At what rate can these non-perfect states reach perfection in an ideal state? Perhaps a Utopia is a world that fades in and out of existence as it deals with non-perfect states as they develop. I don't know....not really played with these arguments before....
Let me know your thoughts!
