Definition
"A lógica modal" is a branch of logic that deals with concepts of possibility, necessity, and other modalities. It extends classical logic by introducing operators that express how statements can be necessarily or possibly true, helping to analyze philosophical and linguistic problems.
Etymology
The term "a lógica modal" comes from Latin roots: 'logica' meaning 'logic' and 'modal' derived from 'modus,' meaning 'mode' or 'manner.' This reflects its focus on modes of truth such as possibility and necessity. Did you know? The study of modal logic dates back to Aristotle but was formalized much later.
