How are the ideas of transcendentalism shown in Chapter 28?

Transcenentalism is an existence or experience beyond the normal or physical level. When Tom does decide to leave the Joad family, he does so with a new purpose that is a combination of political and spiritual belief. He accepts Casy's belief that there is no individual soul, but instead a collective soul of which each person only has a part, and vows to continue Casy's struggle for better treatment of the workers. This is a turning point for Tom. He previously consigned himself to individualist action for himself and his family, but now wishes to work for the common good.
