Dive into a comprehensive massively open online course on sentential logic, spanning 4 hours and 30 minutes. Master the fundamentals of logic through 49 engaging lessons, starting with an introduction and overview before delving into simple sentences, logical operators, and truth tables. Progress to more advanced topics such as replacement rules, logical laws, and various forms of syllogisms. Develop critical thinking skills by learning proof strategies, including proof by contradiction and conditional proofs. Practice with increasingly complex problems, explore tautologies, and understand common logical fallacies. By the end of this course, gain a solid foundation in logical reasoning and argumentation techniques applicable to various fields of study and everyday life.
