That bit was great, I would taken *a lot* of persuading that was safe! Iain Stewart is one of my favourite BBC documentary makers, I ofetn wish I'd studied Geology as being able to look at a landscape and see how it formed and how old it is must be an awesome dimension of awareness to have. I spent some time in Israel and used to go wandering in the desert and trying to figure out what could have happened to make it look like a huge piece of the Earth's crust had been picked up dropped from a great height. I'm sure the answer will be in his new series at some point. > On the Dawkins topic: for me the core of the debate seems to lie in > understanding the nature of cognitive dissonance or what you call weird > disconnect or wooly thinking.

I asked him if I could meditate in one as his are the state of the art at London's main teaching hospital, but he couldn't see the point. And he gets researchers queueing round the block to finish ground breaking work. No time for curious old hippies! > On the acupuncture topic: I've never done it.

I know lots of people who get a lot out of acupuncture and some who got nothing, like Bhairitu. What interests me is that something I had always assumed had something going for it due to it's great age and sophistication, and it turns out it can't survive a run in with the great leveller of scientific method! But that's how placebo works, the more complex and arcane the system, the greater the message to the unconscious to set off the effect.
