its not that its doubtful we will ever understand it. its that by definition any answers about the reality of metaphysics are by nature completely out of reach to beings limited in nature.
I've read your posts on this subject before and you almost make my blood boil. It is not only hugely pretentious to say that we cannot know, but also hugely ARROGANT to say YOU KNOW that we cannot know! Can you not see the hypocrisy and irony in what you are stating?!
Please start saying we don't know, rather than (you know)we can't.
