If we are trying to prove something, either scientifically or philosophically, the burden of proof is with the person claiming the positive result. So if you claim something exists that burden is with you. Now if you ask one of the experts with in the IP world to prove their positive, they don't, why?
--Um, I'm not sure which IP experts you're referring to, but I've asked several to prove themselves to me, and they all have very handily. But here's the thing; in each case I actually had to pull my fat ass up off the couch, get dressed, and venture to their location. I even had to fly to Japan a couple of times. Not a single one of those IP experts knocked on my door and begged to show me their stuff. I'm not sure why that seems unreasonable to you; could you explain further?
