Edit: I'm adding some words from an email Cláudia sent today:
The Cheshire Cat is one of the most frightening characters in universal fiction. Its smile is pure mock of our need of wholeness and clear distinction between objects in the world. We are always looking for light, transparency and well cut shapes. We don't like blur because we cannot divide blur into small pieces. The Cartesian reasoning demands us to understand the pieces to get to the whole but what do we do if we can't separate the pieces?
Well, I've written about uncertainty as if it were something I can handle in a serene Zen way. But I don't always enjoy it, no, no.
