So, in the end, I think we must allow the use of brains to think about thinking; and the use of evolved brains to think about evolution; and the use of inductive brains to think about induction; and the use of brains with an Occam prior to think about whether the universe appears to be simple; for these things we really cannot unwind entirely, even when we have reason to distrust them. Strange loops through the meta level, I think, are not the same as circular logic.
And this have a lot of similarities with my previous conclusion (with significant differences about circular logic and meta loops)

Thank you. This reply actually answer the first part of my question.
The ‘working’ presuppositions include:
Induction
Occam’s razor
I will quote most important part from Fundamental Doubts
