I agree 100%, but I'll try to make the case from my agnostic point of view.I like to hold ideas in my mind that are both possible in themseves, but contradictory in relation to each other. I know i know, Jung wouldn't recommend it, but it's how my mind works. Easy example, perception is local, reliable/ perception is non-local, fictional. So yes, in making this statement on this forum I'm accepting the realness of it. The word belief has always struck me the wrong way though, it feels more like a leaning to me. I hear what you're saying though, it's mastubatory to quote the matrix or Descartes conversationally because the conversation itself is based in certain logical assumptions. Abstract absolute doubt is useful as a thought excercise. It helps me to think with zero boundaries and no ego regarding any concept or problem I'm focusing on.
