Very rarely will the mind confess to us it has no idea what is going on.
This goes both ways. It’s possible to use a belief in the ideas that I know and that I don’t know as a protection.
I know becomes a protection against admitting I don’t really know. He is wrong, is it true? Can I know for certain?
And I don’t know becomes a protection against admitting what I do know. What do I know that I don’t want to know?
