This subtopic investigates the nature and limits of human knowledge, critically examining classical and contemporary sceptical challenges to our claims of knowing. Students explore foundational concepts such as truth, belief, and justification, applying them to key philosophical thought experiments like Gettier cases and brain-in-a-vat scenarios. The practical application lies in developing rigorous analytical skills to assess the reliability of our cognitive faculties and the strength of arguments for and against radical doubt.
