The theological discussion has been fascinating, but as I am completely unqualified to add anything there, I thought I would add a philological observation, which is more my bailiwick ...

It's a shame Pearce didn't remember Tolkien's own explicit disavowal of that very etymology:
"To take a frequent case:
there is no linguistic connexion, and therefore no connexion in significance,
between Sauron a contemporary form of
an older *θaurond- derivative of an
adjectival *θaurā (from a base √THAW)
'detestable', and the Greek σαύρα 'a lizard'." (Draft to Mr. Rang, Letters, #297)
Yes, all too frequent a case. Edmund Wilson, Mr. Rang, and now Joseph Pearce. It appears we need some kind of FAQ: "Middle-earth is not Jurassic Park".
PS. Sorry if the Greek letters don't come through. The Latin transliteration of σαύρα would be saúra.
