> It sounds like the kind of thing that Russell Brand was wittering about a couple of years ago - that your senses are the only way to interface with reality, and if you can't sense it it's not there,

Can you post a source for this? I listened to a few bits of Brand over the years, and on this subject he'd say that there's a lot more reality out there, but humans are simply unaware of it due to our limited human senses. Nothing non obvious or controversial.
