Natural Deduction is a method in formal logic used to derive conclusions from premises through a structured set of rules. It allows for the direct application of logical principles, enabling the construction of valid arguments step by step. Each step follows logically from the previous ones, ensuring clarity and rigor in reasoning. In Natural Deduction, rules are categorized into introduction and elimination rules for various logical connectives, such as conjunction, disjunction, and implication. This system emphasizes the importance of proof construction, making it easier to understand how conclusions are reached and to verify the validity of arguments in a systematic way.
