Your reason doesn't decide whether you are in a trickster universe or not. That is a limit of reason.
You could be in a trickster universe and think the same.
The point is that it is a limit for knowledge. For all you and I know only of us could be real in the following sense: Imagine a Boltzmann Brain universe where one of us is on a computer running and the other is a part of the simulation run by the computer. The rest of the universe, as it appears, is a simulation on the computer.
Now consider this:
I see no reason to suppose that I am in a trickster universe, and therefore I will ignore the idea.
I see no reason to suppose that there is no creator God, and therefore I will ignore the idea.
In both cases "I see no reason", will not determine what the really real reality is and there is no functionally difference between the cases of "I see no reason".
I am a skeptic and I try to understand the limits of reason, logic and what not.
I look for the limits of "I see no reason to suppose that I am in a trickster universe, and therefore I will ignore the idea." The limit is that it will not decide what universe you are in.
I know that as a skeptic and I know that I believe in God will not decide what kind of universe I live in.
So do you think, how you think, will decide what kind of universe you live in?
Apparently that is the limit of epistemology and if you Know differently, I like to know how?
