Do you think that Eustace, a character in C.S. Lewis "Chronicles of Narnia", represents atheists?

I think Eustace, the white witch, and eventually Susan all represent a moving away from childhood fascination with magic and fantasy (which Lewis equates with spirituality). I disagree with Lewis' ociation of fascination with fantasy with spirituality. I think that cheapens spirituality and dampens fantasy. I consider true spirituality to be a life-long, objective search for "truth" and fantasy to be something like the most pure form of fun (literally, creating new worlds of imagination).
