Tom Joad's farewell and mission

Tom Joad's farewell and mission is the climactic transformation of the novel, in which the fugitive killer, hiding in a cave after killing a vigilante, articulates a new philosophy of collective action and social justice, vowing to be present wherever people struggle for dignity and food, and thus becomes the spiritual heir of the martyred preacher Jim Casy.

The Circumstances of the Farewell

After Ruthie Joad, in a childish fight over Cracker Jack, revealed that her brother was hiding from a killing, Ma Joad knew Tom could no longer stay with the family. She crept through the willows beside the stream to the culvert where she left his food, and then into a thicket to wait. When Tom appeared, she followed him to his hideout—a cave beneath a great mound of wild blackberry vines, where he had been living "like a rabbit." In the absolute darkness, Ma could not see him; she touched his face, feeling the bad scar and his crooked nose, and pressed seven dollars into his hand, insisting he take it. She wanted him to go far away, to a big city like Los Angeles where they would never look for him.

Tom's Reflection on Casy's Philosophy

Tom had been alone in hiding for days, and the solitude had forced him to think. He told Ma that he had been remembering everything Jim Casy said. Casy had gone into the wilderness to find his own soul, only to discover he had no soul that was his alone—he had just a little piece of a great big soul, and that little piece was no good unless it was with the rest and whole. Tom now understood that "a fella ain't no good alone." He recalled Scripture Casy had quoted twice, from the Preacher: "Two are better than one, because they have a good reward for their labor. For if they fall, the one will lif' up his fellow, but woe to him that is alone when he falleth, for he hath not another to help him up." And the rest: "Again, if two lie together, then they have heat: but how can one be warm alone? And if one prevail against him, two shall withstand him, and a three-fold cord is not quickly broken." Ma asked if that was Scripture, and Tom said Casy called it the Preacher.

The New Mission

Tom told Ma he had been thinking about how it was in the government camp, where the people took care of themselves and kept order without cops waggling their guns. He wondered why they could not do that everywhere—throw out the cops that were not their people, all work together for their own thing, all farm their own land. When Ma asked what he aimed to do, he answered simply: "What Casy done." Ma protested that they killed Casy, but Tom said Casy did not duck quick enough; he was not doing anything against the law. He had been thinking about their people living like pigs while the good rich land lay fallow, or one fella with a million acres while a hundred thousand good farmers were starving. He wondered what would happen if all their folks got together and yelled, like the few of them at the Hooper ranch. Ma warned they would drive him and cut him down like they did to Pretty Boy Floyd. Tom replied, "They gonna drive me anyways. They drivin' all our people." He admitted he had not thought it out clear yet, but as long as he was an outlaw anyway, maybe he could do something.

The Vow: "I'll Be There"

When Ma asked how she would know about him—if they might kill him and she would not know—Tom laughed uneasily and said maybe, like Casy said, a fella does not have a soul of his own, only a piece of a big one. Then it did not matter: "I'll be all aroun' in the dark. I'll be ever'where—wherever you look. Wherever they's a fight so hungry people can eat, I'll be there. Wherever they's a cop beatin' up a guy, I'll be there. If Casy knowed, why, I'll be in the way guys yell when they're mad an'—I'll be in the way kids laugh when they're hungry an' they know supper's ready. An' when our folks eat the stuff they raise an' live in the houses they build—why, I'll be there. See? God, I'm talkin' like Casy. Comes of thinkin' about him so much. Seems like I can see him sometimes." Ma said she did not understand, and Tom admitted he did not either—it was just stuff he had been thinking about, and a person thinks a lot when he is not moving around. He took the money, and Ma left him, her eyes wet and burning but not crying. As she went, the rain began to fall, big drops and few, splashing on the dry leaves heavily.

The Significance of the Transformation

Tom Joad's farewell marks the completion of his arc from a paroled killer who killed a man in a drunken fight to a conscious organizer willing to sacrifice his safety for collective justice. His vow echoes and extends Jim Casy's philosophy of the "one big soul" and the holiness of human connection, transforming it into a political and spiritual mission. The "I'll be there" speech is the novel's most direct statement of solidarity and the belief that individual salvation is meaningless without communal struggle. Tom's departure also signals the final dissolution of the Joad family as a self-contained unit, even as his mission represents the family's values projected outward onto the larger community of the dispossessed.
