Plantinga's Modal Logic

Alvin Plantinga's modal logic explores the nature of possibility and necessity using tools from formal logic and philosophy. It considers different "possible worlds" to analyze whether statements could be true or must be true. For example, something necessarily true is true in all possible worlds, while something possibly true is true in at least one. Plantinga uses this framework to examine questions about God's existence, omnipotence, and the nature of reality, providing a rigorous way to think about what could be true versus what must be true in different hypothetical situations.
