During the court trial in the book “To Kill a Mockingbird” by Harper Lee, Atticus best uses the rhetorical device of logos to influence the Juryjury. Logos is defined as using rationality to help prove your point towards something. By being logical and using evidence from the case, Atticus could help prove the fact that Bob Ewell could have been the actual abuser. Atticus asks Mayella to describe her injuries and proves Bob may have punched her because his left hand is dominant. According to the book, “...there is circumstantial evidence to indicate that Mayella Ewell was beaten savagely by someone who led almost exclusively with his left...he swore out a warrant, no doubt signing it with his left hand, and Tom Robinson now sits before you, having taken the oath with the only good hand he possesses - his right hand”(232). This proves Atticus’s speculation that Bob Ewell could have potentially been the attacker while Tom Robinson could not have. One might argue that throughout the trial, Atticus best uses emotionsemotion or sympathy to help influence the Judgejudge. Atticus did use these types of rhetoric to sway the jury and show that people of any color should be treated with equality. However, logos was much more effective during the trial compared to ethos and pathos. Atticus does use all forms of rhetoric to prove his claim, but, he mainly used logical reasoning to prove Tom’s innocence. If Atticus did not show any sort of rationality throughout the case, the jury would have declared Tom guilty much sooner into the case.
