What does Ms. Maudie tries Jem to understand?

Jem is discouraged and disappointed with the people of Maycomb, who he formerly thought were "the best people in the world." He thinks that no one but Atticus worked on Tom's behalf, but Miss Maudie points out that many people helped, including Mr. Tate the sheriff, the black community, and especially Mr. Taylor the judge, who offered Atticus the case in the first place. Mr. Tate assigned Atticus to the case because he knew Atticus would truly dedicate himself to the cause. Miss Maudie says that even though she knew Atticus couldn't win, he did manage to keep the jury out in discussion for longer than anyone else could, which is an achievement in and of itself. She says, "we're making a step - it's just a baby step, but it's a step."
