Introduction to Critical Thinking and Logic
A 29-hour grounding in informal and formal logic built for anyone who wants sharper reasoning rather than a survey of philosophers. Saylor Academy's course opens with meaning analysis and argument structure, then moves into informal fallacies, formal logic, Venn diagrams, scientific reasoning, and strategic and creative thinking, treating each new unit as a layer on top of the last. The stated aim is practical: becoming a more careful reader and listener, a more persuasive writer, and a more rigorous researcher, skills the course frames as useful across law, science, and the humanities alike. It includes a free certificate of completion and is recommended for college credit. All videos, readings, and the course syllabus are free with no login required to start. It pairs naturally with a content-heavy ethics course as the toolkit for evaluating the arguments in it.
