What is the process for testing the validity of a categorical syllogism using Venn Diagrams?
To test validity, draw three intersecting circles representing the terms, diagram the premises, and see if the conclusion is already diagrammed. If so, the argument is valid; if not, it’s invalid.
What does a Venn Diagram help us understand?
A Venn Diagram helps us understand the relationships, similarities, and differences between different classes or categories through visual representation.
