Routley diagrams

Routley diagrams are visual tools used in logic to represent different possible worlds and how they relate, especially in non-classical logic systems like relevance logic. They display points (worlds) connected by relations (like accessibility), allowing us to analyze how truth values change across different scenarios. By using these diagrams, logicians can better understand how certain statements hold or fail depending on the context or "world" considered, providing a clear way to explore complex logical relationships beyond traditional true/false evaluations.
