I don't know. Does it matter? Even if I plainly see it produce a chocolate bunny, for what reason would I need to make up my mind on that? I fail to see the utility. "I don't know" remains a sufficient state going forward.

I don't know.

I don't know. And I don't have a justification. For what reason would I need one?

Infinite regress implies making up a mind, no? But since there is no real need to do that...

That's a different question. I'm not asking whether you have a reason to make up your mind on the question, just whether it's rational to think one or the other.

Couple more questions:

Is math an area where you can make up your mind?

Do you know whether you know the answer to the question I posed above? Which was:

>> "Everything I know, I know with the certainty of math, or not at all". Which of the two does this statement itself fall into?
