I don't think I would ever have argued with that.

Mechanical languages though, mechanical systems. Not particularly interested in quantum physics. That breaks things down so much to the point that everything can unfold into a somewhat distorted method of processing your own knowledge. Like trying to understand something from both yourself, and what is not yourself.

Mathematics. Logic. Those things can be accepted at face value. I think that's the closest one can get to complete knowledge. That's my opinion though.
