In the book the Art of Great Speeches the term "Evidence" as it relates to a speech/speech-writing is defined as the most important part of the speech and should be presented in an interesting and appealing manner. In the opening of the chapter it is suggested that a great speech requires more than appeal to the emotion of the audience, showcase the speaker's personality, and exhibit style. A great speech also requires: purpose, substance, structure, evidence, and logic; or what the Greeks referred to as logos. The chapter addresses divisions of a speech, classifications of a speech, and how facts should be used to have the greatest impact in a speech. Evidence/logos within a speech is essential in order for the audience to receive the central message of the speech and to follow the call of action. Generally, the preconception of an audience member is not easily pushed aside. If a speech is difficult to follow and if the argument is fairly weak, the audience member will find it easy to dismiss the speaker's ideas. On the other hand, an organized, clear, and logical argument will be difficult for an audience member to ignore. When combined with a good ethos and pathos, a strong logos will evoke the most stubborn audience member to strongly reconsider his/her ideas.
For my speech topic I will be writing on Veterans and PTSD (Post Traumatic Stress Disorder). I am a military veteran and I know of many fellow veterans who suffer with this mental health issue. I feel that the level of awareness for PTSD isn't as raised as it should be. I also feel that the types of treatment for PTSD should be more in depth and accessible to those who suffer. I want to expand my knowledge of and help bring awareness to PTSD others.
