But think of Adam and Eve like an imaginary number, like the square root of minus one: you can never see any concrete proof that it exists, but if you include it in your equations, you can calculate all manner of things that couldn't be imagined without it.
Lord Asriel in The Golden Compass (which is soon to be a major motion picture), by Phillip Pullman
though i'm a little sad for the movie, because the script was originally to be done by tom stoppard, who is quite fun, and having just finished pullman's book and having read some stoppard in the past, i think tom would have done a good job because the material (haha its a word joke. the pullman trilogy is called His Dark Materials (which, if you read the very beginning of the book, you'll find is from Paradise Lost)) seems well suited for him.
