What is logic in argumentative writing?
• “Logic is a formal system of analysis that helps writers • invent,
• demonstrate,
• and prove arguments”
• “To be logical, a proposition must be tested within a logical sequence.”

How does it work?
• “It works by testing propositions against one another to determine their accuracy” to form a conclusion.• Proposition: a statement or assertion that expresses a judgment
or opinion.
• Premise: Proposition used as evidence in an argument.
• Conclusion: Logical result of the relationship between the premises. Conclusions serve as the thesis of the argument.

Example
• Premise 1: All men are mortal.
• Premise 2: Socrates is a man.
• Conclusion: Therefore, Socrates is mortal.
• Aristotle
• This sequence of premise to conclusion is know as a Syllogism

How to use logic in your writing?
• To use logic in argumentative writing:• “lay out each premise clearly
• provide evidence for each premise
• draw a clear connection to the conclusion”
• Logic does not always work to prove your argument because people/readers use other tools to determine accuracy like emotions or experiences.
