Routley-Meyer semantics

Routley-Meyer semantics is a way to understand modal logic—how “what is possible or necessary” works—using a special kind of model. It involves a set of worlds or situations, with relationships between them that show how one world relates to others. Each world has specific truths, and the relationships help determine whether a statement is necessarily true or possibly true across different scenarios. This approach provides a precise, formal framework for analyzing modal concepts, especially in areas like philosophical logic and theories involving possibility and necessity, by capturing how truth varies across interconnected worlds.
