Formal Logic
Formal logic is a branch of logic that focuses on studying the formal structure and rules of reasoning. It employs symbolic and formal methods to ensure the rigor and validity of the reasoning process. The goal of formal logic is to construct a complete system of symbols and rules of inference to accurately express and verify the logical relationships between propositions. Its application value is extensive, not only serving as a foundation in philosophy and mathematics but also being used in computer science, artificial intelligence, law, and other fields for automated reasoning, knowledge representation, and decision support.
