And so what he's trying to do is to as Andrea says erm uncover the truth, get to the, get to what really happened as it were, under the layers of myth and distortion could have been introduced in the Bible story, and as I said if you read the book erm and it is quite fascinating in many ways, it is a bit like a detective story because what Freud does is he tries to get to the truth by analyzing the, the actual texts and the texts contains discrepancies and anybody who's ever tried to erm edit a book, learns this to their cost actually, but er you find no matter how carefully you change things, there's usually things you miss, little discrepancies that give away how it was the first time and er Freud's view is this, this has happened very much to the Bible, it's been so heavily edited and re-written and later  the  the various editings show and if you read it very critically, you can begin to see perhaps the underlying pattern er coming through and erm just as you can tell for instance by reading Genesis, that it's a  of two accounts because there are two  stories, the first  story is Chapter One of Genesis, then in Chapter Three or something there's a second story repeats it with variations.
