One is not idle because one is absorbed. There is both visible and invisible labor. To contemplate is to toil, to think is to do. The crossed arms work, the clasped hands act. The eyes upturned to Heaven are an act of creation.
I love that contradiction between the ugly and the nice. It's shot in a very gourmet way in the Perfume: The Story Of A Murderer. But then Grenouille doesn't differentiate between what's commonly considered to be good smells and bad. He just takes it all, like a true collector does.
