“the sense of being which in calm hours arises, we know not how, in the soul, is not diverse from things, from space, from light, from time, from man, but one with them and proceeds obviously from the same source.... Here is the fountain of action and of thought.... We lie in the lap of immense intelligence.” ― Ralph Waldo Emerson
"Lookie , Ma. I been all day an' all night hidin' alone. Guess who I been thinkin' about? Casy! He talked a lot. Used ta bother me. But now I been thinkin' what he said, an' I can remember---all of it. Says one time he went out in the wilderness to find his own soul, an' he foun' he didn' have no soul that was his'n. Says he foun' he jus' got a little piece of a great big soul. Says a wilderness ain't no good, 'cause his little piece of a great big soul wasn't no good 'less it was with the rest, an' was whole. Funny how I remember. Didn' think I was even listenin'. But I know now a fella ain't no good alone." (p 418)
The Transcendental concept of the Oversoul is expressed in the earthy folk language of Tom Joad and Jim Casy as the belief that all human's souls are really just part of one big soul. Ralph Waldo Emerson, the most well known proponent of transcendentalism, defined the Oversoul as the universal mind or spirit that animates, motivates, and is the unifying principle of all living things. In The Grapes of Wrath Casy makes numerous references to this one large soul that connects all in holiness, and they dovetail nicely with the basic idea of strength in group unity.
Somewhat conversely, American transcendentalism also recognized individualism, a faith in common people and their self-reliance. This concept of the survival of the human life force is symbolized by the survival of the land turtle and Ma's comment, "We're the people — we go on." This combination of rugged individualism and an embracing of all men as part of the same Great Being is physically expressed in the education and re-birth of Tom Joad: His strongly individual nature gives him the strength to fight for the social welfare of all humanity.
