About this course

How can we be certain of what we know? Is true knowledge even possible? For centuries, philosophers have grappled with these fundamental questions, developing a rich tradition of thought known as skepticism. This course offers a clear, text-based journey through the history of philosophical skepticism. You will start with the ancient Greek thinkers who first challenged claims of absolute truth and travel through the pivotal arguments that shaped Western thought. By the end, you will not only grasp the core concepts of skepticism but also develop a more rigorous and thoughtful approach to evaluating claims and your own beliefs. What you'll learn: - Understand the core principles of skepticism, from its origins with Pyrrho to its modern applications. - Analyze the key arguments of influential thinkers like Sextus Empiricus, Montaigne, and David Hume. - Explore the historical impact of skeptical thought on religion, science, and political authority. - Distinguish between different forms of skepticism, such as academic skepticism and Pyrrhonism. - Apply skeptical methods to evaluate arguments and information in contemporary life. - Practice deconstructing and forming philosophical arguments through written exercises. The course begins with foundational terminology and the central problems of knowledge. From there, you will progress chronologically through the major periods and figures, reading concise explanations of their ideas and significance. This course is designed for absolute beginners. No prior background in philosophy is required to start learning. Begin your exploration of philosophical doubt and strengthen your critical thinking skills today.

It's a solid course. The structure is logical and most of the examples were helpful. Could use a few more real-world scenarios though.

Hmm, I wasn't entirely convinced. The examples given didn't always seem to match the theory, and it felt like a lot of information was glossed over. Felt a bit incomplete.
