Natural deduction is a method in formal logic used to derive conclusions from premises through a structured set of rules. It emphasizes the intuitive aspects of reasoning, allowing for the direct application of logical principles to reach valid conclusions. This approach is often used in mathematical proofs and philosophical arguments. In natural deduction, each step in the argument is justified by a specific rule, such as modus ponens or introduction and elimination rules for logical connectives. The goal is to demonstrate the validity of an argument by showing that the conclusion follows logically from the premises without requiring additional axioms or assumptions.
