Fallacies in Famous Speeches

1. "Let both sides unite to heed in all corners of the earth the command of Isaiah -- to 'undo the heavy burdens... and let the oppressed go free.'"
2. In this quote, John F. Kennedy commits the fallacy of Appeal from Authority. JFK uses a quote from Isaiah, who is an authority figure or an expert to many religious people. This is a fallacy because even though Isaiah is a figure of authority, his words may not necessarily be credible or true. He is using these words to try to persuade his audience, so it is a fallacy.
3. Even though this speech commits so many fallacies, it is so effective and still famous today because JFK used the fallacies in a way that made them believable and easy to agree with. Most of the fallacies that he used in his speech are used to stir up some sort of emotion or rally the people of America, so that very easily can cover up the fact that they really are fallacies. If people are having their spirits raised and being rallied, they probably won't be paying much attention to the credibility of the argument. Also, JFK used fallacies that people were sure to agree with, like Appeal to faith, Appeal to tradition, Argumentum ad baculum, and many others.
