Readers don't actually catch a glimpse of Boo Radley until the end of To Kill a Mockingbird. For most of the story, we see him through Scout's eyes, and Scout is terrified of him. She doesn't realize it, but she is far more terrified of the Boo Radley that she has created in her mind than the actual man, who is quiet, shy, caring, and tremendously courageous.

When Bob Ewell attacks Scout and Jem one night, Boo Radley defends them vigorously, killing Ewell in the process. He is not about to let the man hurt the children, and he knows that Ewell is out to do more than hurt them. Ewell wants revenge on Atticus in the lowest way possible—namely, killing his children. So Boo steps out of his home and saves the day.

As Scout tells the story to her father and Mr. Tate, she does not yet know that Boo has been involved. She remarks that Ewell was trying to squeeze her to death but then “somebody yanked Mr. Ewell down.” She thinks it was Jem, and then she thinks that Atticus had arrived on the scene. Then she turns around to see her rescuer.

Boo Radley is standing against the wall in Jem's bedroom. He is clearly uncomfortable, even frightened, at being outside the safety of his own home. Yet there he stands, and perhaps this requires more courage than his action against Ewell. As Scout looks at him, he presses his hands against the wall, trying to steady himself. He shakes a bit, but then “the tension slowly drained from his face,” and his “lips parted into a timid smile.” Boo Radley has just conquered one of his greatest fears with the help of a little girl.

Scout suddenly finds herself in the role of Boo Radley's comforter and guide. She leads him to a chair on the porch where he will be comfortable and sits beside him. The fact that Boo sits there at all again shows that he is conquering his fear. Scout and Boo then listen the conversation between Atticus and Mr. Tate. At first Atticus thinks that Jem accidentally killed Ewell, but Mr. Tate knows what really happened, and he finally convinces Atticus. However, Mr. Tate will maintain on the record that Ewell fell on his knife. He does not want Boo exposed to the grateful limelight of the town, which would overwhelm the recluse. Before Scout guides Boo home, Atticus turns to him and says, “Thank you for my children, Arthur.” Boo touches Jem's hair a little as he says goodbye—another victory for him—and then Scout takes her hero home.

Boo Radley's actual saving the children from Bob Ewell is cited in the actions during which Scout narrates as if there is a man she does not know in the action of the story. She reports:

"The man was walking with the staccato steps of someone carrying a load too heavy for him. He was going around the corner. He was carrying Jem. Jem’s arm was dangling crazily in front of him. By the time I reached the corner the man was crossing our front yard. Light from our front door framed Atticus for an instant; he ran down the steps, and together, he and the man took Jem inside."

This demonstrates the man we later come to identify as Boo has just recovered a broken Jem from under the tree that Bob Ewell lies under dead. To cross Bob Ewell, a drunk man with a kitchen knife in the dark, can certainly be considered dangerous.

Another one I like is from Atticus. After Atticus is convinced that Jem destroyed Bob Ewell, Mr. Tate works Atticus over convincing him that Jem couldn't have done it, and that it could look like and accident. However, Tate insinuates Boo's heroism. Atticus finally acknowledges it:

Before he went inside the house, he stopped in front of Boo Radley. “Thank you for my children, Arthur,” he said.

How about this quote from chapter 30? Heck Tate is trying to convince Atticus that it was NOT Jem who killed Bob Ewell. Atticus thinks it was Jem and that Heck Tate is trying to say that Bob Ewell fell on his knife to protect Jem, when really, Heck Tate is trying to protect Boo Radley. It was Boo who stabbed Bob Ewell to protect Scout and Jem, who he has been watching over. Heck Tate tells Atticus:

"I never heard tell that it's against the law for a citizen to do his utmost to prevent a crime from being committed, which is exactly what he did, but maybe you'll say it's my duty to tell the town all
about it and not hush it up. Know what'd happen then? All the ladies in Maycomb includin' my wife'd be knocking on his door bringing angel food cakes. To my way of thinkin', Mr. Finch, taking the one man
who's done you and this town a great service an' draggin' him with his shy ways into the limelight- to me, that's a sin. It's a sin and I'm not about to have it on my head. If it was any other man, it'd be
different. But not this man, Mr. Finch."

This shows that in spite of being a recluse, in spite of being the subject of ridicule, Boo Radley was, in fact, a pretty brave guy when it came to his secret "friends" - Scout and Jem. The reader learns at the end of the novel that Boo has been doing more than just leaving trinkets in the tree stump for Jem and Scout. He has been watching out for them and winds up protecting them from a crazy drunk white trash lunatic, when the rest of the citizens of Maycomb, including Atticus, Heck Tate and the police, could not.

This is a good quote with which to end your essay, since you are at the end of it. You do not need to use the entire quote, though. I think it would be a good one to use to prove that Boo is brave. Many people are underestimated in this novel, and Boo is perhaps one of the most underestimated. He turns out to be the hero -- how about that? It is one of the great ironies of this novel that the person the children have feared the most turns out to be the one who saves them.

We know that ever since Boo was arrested for his “wild” antics with some friends and sent to a reform school, he has been hiding away in the Radley house. Whether or not this hermit-like existence is forced upon him by his father and brother, or if it is a choice, is debatable. We will never know because Harper Lee doesn’t ever give us details about what is really going on with Boo and his family. There are so many rumors about Boo, and no one really knows the truth. However, whether Boo is locked away for his own good or whether it is self-imposed, perhaps venturing out of the house could be a sign of courage for Boo.

When Boo leaves presents for Scout and Jem in the knot hole of the tree, he is really telling them something about himself. The carved soap figures, the gum, and especially the spelling medal shows Scout and Jem that he is not the scary phantom that peeps in peoples’ windows and eats squirrels. He is going against the rumors and superstitions that surround him and wants to prove to Scout and Jem that he is normal. This shows Boo’s courage to reach out and dispel the stories about him. In addition, he covers Scout with a blanket during Miss Maudie’s fire, bringing him out of the house and in the sight of others. Although undetected by anyone, this does show Boo’s courage to help Scout and show his compassion.

If Boo has chosen to keep to himself for whatever reason—maybe he hates society and what it represents or he is embarrassed by his past—venturing out of the Radley house shows his courage to want to change and be different from the tall tales and superstitions that surround him. Although small acts, these decisions by Boo could show that courage isn’t necessarily just saving a life but is doing something so extraordinary that no one would believe it.

Because these events are the only time we see Boo Radley in the story, we must make inferences to the meaning of them and how they could show an inkling of courage by our favorite mockingbird, Boo.

What is a quote that demonstrates Boo Radley's personality in To Kill a Mockingbird?

Depending upon how far along you have read in To Kill a Mockingbird, you have probably already discovered that Boo is both mysterious and invisible to nearly everyone. Apparently, aside from his family, only Atticus and the town doctor have seen him in recent years. Miss Maudie describes him as a nice, polite boy when he was a teenager, but little is known about him until the very end of the novel. In the last chapters, Boo finally makes his appearance, and Scout gets to observe him up close.

     His face was as white as his hands... His cheeks were thin to hollowness; his mouth was wide... and his grey eyes were so colorless I thought he was blind. His hair was dead and thin...
     A strange small spasm shook him... but as I gazed at him in wonder the tension drained from his face. His lips parted into a timid smile...

Scout's brief encounter with Boo doesn't reveal much about his personality, but she comes to understand that he must have been watching out for her during the walk home from the Halloween pageant. When Boo spoke for the only time, it was in a whisper. He gently took Scout's hand when she walked him home, and it was the last time she would ever see him. She later stood on the Radley porch, looking out upon the neighborhood as if through Boo's eyes. He was no longer a night prowler, but a concerned neighbor who gave secret gifts, watched children play, and came to their aid when he was needed. 

Please help me with a qoute from Boo Radley in the novel, To Kill a Mockingbird.

As you probably know, Boo is one of the main characters during the first part of Harper Lee's novel, To Kill a Mockingbird. Jem and Scout (and Dill) spend most of their time trying to lure Boo out into the open. They become even more inquisitve after they begin receiving the mysterious gifts in the knothole of the Radley oak tree. However, Boo is neither seen nor heard until the final chapters of the book. After he saves Jem and Scout from the attack by Bob Ewell, he finally appears, lurking in the shadows of Jem's bedroom. He only speaks one line in the entire book. After softly touching the sleeping Jem's hair, he "almost whispered" to Scout,

    "Will you take me home?"
