Also:
¬(P(X|A) = P(¬X|A) = 1)
Therefore, for any evidence A, Value of information > 0.
Contradictions are not failure conditions in trivialsim.
I wasn't positing this as a failure condition within trivialism, but of trivialism.
According to what I'm seeing here, a perfectly trivialist agent sees no difference between the truth of dying when shooting themselves in the head, the truth of not dying when shooting themselves in the head, and the truth of dying and not dying when being alive. No imaginable action can have any effect on the world, because everything is true, and so there's no real reason to do anything, including living. This too is true, as is the opposite, to said agent.
Basically, a trivialist assigns the null hypothesis over whether to care or not about the universe and themselves? Everything is true, but that doesn't consist in a reason to not act? Everything is true when it lets you write a paper and get grant money, but otherwise some things can safely be considered false for the purposes of living a normal life?
How convenient can question-begging get? Can I become a billionaire doing nothing but this? ("Yes, that's true." says the trivialist)
The way I see it, trivialism rejects logic and any kind of possibly imaginable rule for the purposes of writing philosophy papers, but conveniently ignores itself whenever it's time to go home or eat or live a perfectly normal life just like they would if some possible things were actually false.
Lots of strawman in there- especially with the assumption that trivialism implies meta-trivialism.
Doesn't the strict rationalist have trouble with the truth value of statements conditioned on false statements?
You are looking for a philosophy which tells you what the indicated course of action is. That means that trivialism is poorly suited for you.
You are looking for a philosophy because you want your philosophy to tell you what you should do. That means that trivialism is the perfect philosophy for you to practice.
Trivialism is not nihilism, and only a perfect trivialist could believe that it was.
As a final koan: Why are the characteristics of trivialism that you list negative? So what? Why does that matter?
Sorry, not my intention to strawman. It is alien to me.
No. Not bayesians, at any rate.
What's an "indicated" course of action? How is it different from "what you should do", below?
What does trivialism predict? What does it tell us to do? Does trivialism let me predict anything more accurately than any other theory? A single instance of one thing that it would predict more accurately and/or reliably in reality than any other theory would make it instantly much less worthy of derision.
At present, it is to me nothing more than a humorous thought experiment similar to "This sentence is false."
