Logic is the study of reasoning and argumentation, focusing on the principles that govern valid inference and correct reasoning. It provides a framework for evaluating the truth of statements and the relationships between them, making it essential in fields like philosophy, mathematics, and computer science. In its various forms, such as Propositional Logic and Predicate Logic, logic helps us understand how to construct sound arguments and identify fallacies. By applying logical principles, we can analyze complex problems and make informed decisions, enhancing our critical thinking skills in everyday life.
