Another sizzling paper has just materialised on the Astrozero site -

http://www.astrozero.co.uk/articles/chain.htm to be precise.

In this paper, originally written for the MA program at Bath Spa University, Judy Hall advances a case for considering that the idea of a 'chain of being' should be traced, not to the Greece of Plato et al, but rather to the earlier civilisation of Mesopotamia; and that the influence of this idea may also be preserved in the Kabbalah's tree of life.

Thanks for the link Garry. I'm looking forward to reading this and the article that you wrote recently.
