What is a Syllogism?
A syllogism is a form of logical reasoning that draws a conclusion from two premises. It's a structured argument that typically consists of three parts:
1. Major Premise: A general statement.
2. Minor Premise: A specific statement related to the major premise.
3. Conclusion: A statement derived logically from the two premises.
