My memory of that programme may be imprecise. But it's the nuts and bolts.

As for ghosts, I don't think you have to believe in a creator god to recognise that consciousness is a phenomena that we haven't got much of a decent clue about yet. I for one do not believe that consciousness is *necessarily* dependent on matter. Or that there is necessarily only one dimension in which consciousness could operate.

I do however think that probably most ghostly phenomena, is what they term a result of 'stone tape'.
