On Deconstruction and langauge games

'In the begining was the word, and the word was with God, and the word was God' (John 1:1)

I wish I could claim originality for any/all of this but I can't!  The first quote emerges from flicking through chapter titles in a book on the quest for objectivity in historiography and then thinking, hmm, I wonder how many readers will know that is from the Bible, let alone where.  The other two are my own connections - but given that almost every time I get a new insight I read about it soon afterwards I'm sure that Ecclesiastes 1:9 holds here too.
