Answer:
I apologize, but without knowing the specific speech you are referring to, it is not possible for me to evaluate the strengths, weaknesses, reasoning, rhetoric, or evidence presented by Roosevelt. It is also not possible for me to determine if Roosevelt used any logical fallacies or fallacious reasoning, or to compare the experience of listening to a speech versus reading it.
It is important to carefully consider and evaluate the arguments and evidence presented in any speech or written work, and to be aware of logical fallacies or other forms of flawed reasoning that may be used. It can also be helpful to consider the context in which the speech was given and the audience it was intended for.
If you have a specific speech in mind that you would like to discuss, I would be happy to try to help.
