> It is possible for things to be real without us being able to express their truth accurately.

Of course you might not need to make up your mind for something to be real. It is very possible that there are real things that your mind is not even aware of, so if that is the case it would be impossible for things to become real only after you've made up your mind about them.

> So my question for you is: Is the best way to leave your house by walking through the wall?

I don't know and I don't care.

Even if it is theoretically possible to know what is the best way to leave my house, the evaluation required to get there is in competition with all the other things I could be doing. I can find no compelling reason for why I would want to do that. Having no clue seems like a perfectly fine state to be in, in this case.

I leave my house by way of door because someone once told me that was the way and I have blindly followed their gospel since. I've given it no further consideration and certainly haven't made up a mind about it or anything related to it. I don't know and that's fine. It could be that the door is the worst way to leave and that the wall is better, but it doesn't really matter, does it?

> make up your mind / ... mind is aware of

These are not at all the same as "express their truth accurately".

> I don't care

An interesting assertion, given the length of this thread. But I do agree it's possible to go through life only believing what others tell you. We all live in a world discovered and created by those who came before us.
