Think of it as the "thinking" part of persuasion.
Here are some examples of how logos might be used in rhetoric:
* Using data: "Studies have shown that 70% of people who exercise regularly report feeling happier."
* Presenting statistics: "The unemployment rate has decreased by 2% since last year."
* Offering expert opinions: "According to Dr. Smith, a leading expert in the field, this new medication has shown promising results."
* Constructing logical arguments: "If we continue to pollute our environment, the consequences will be dire. Therefore, we must take action to protect our planet."
Logos is just one part of the "rhetorical triangle," which also includes pathos (emotional appeal) and ethos (credibility and trust). By using all three effectively, you can create a more persuasive and compelling argument.
