What do you believe in that hasnt been proven to exist?

[Excited Penguin]

I think trying to assign such properties as knowable and provable to existence itself is an exercise in futility. Experience of the world is there. The world itself is there, in some sense, no matter what may turn out to be the case. Therefore, I still think this questioning of or indeed belief in reality is simply meaningless and useless at best.

I don't understand your contradiction.  If the assigning the property 'knowable' to existence is futile, then how can 'experience of the world be there'?

Again, you're not getting what I'm saying.  Yes, the world is there, however we take the meaning of 'there' - it is either there outside and irrespective of my consciousness, or it is 'there' only within my consciousness.  I opt - without proof - for the former.

Please understand that I'm not trying to demonstrate that one view or another is correct, but simply answering the question posed in the thread title.

I know that is what you're doing. I was merely attempting a discussion on this point, though , admittedly , this may not be the best place for it .

I will say this though. I believe our experience of the world is ultimately inseparable from what we call knowledge, yes, even allowing for the senses. So to wonder whether reality is ultimately external or internal in relation to our minds is to confuse matters. I believe it is both.
