What kind of themes can be used for the topic of movement in the book The Elegance of the Hedgehog?

What an
interesting way to approach the theme of this book!  I would say there are two ways you could
broach the subject: by focusing on the movement of ignorance toward knowledge or by focusing on
the movement of loneliness toward fulfillment.  Both of these themes can and should be applied
to the characters of Rene© and Paloma; however, I will fully analyze Rene© in regard to the
first theme and Paloma in regard to the second in order to give you some wiggle room in your
assignment.

The first idea of movement and theme would be that of
"ignorance into knowledge."  Renee moves from one to the other in quite a literal
way.  She hasn't had a lot of formal education (unlike many of the tenants in her building), so
she schools herself by reading the classics.  Even Mr. Ozu realizes fairly early on that she has
named her cat Leo after Tolstoy.  But there is a deeper level that Rene© touches upon as well. 
At the beginning, Rene© is confined by her stuffy French society.
