Using Nаgel’s discussiоn оf skepticism, reflect оn whаt it meаns to know something. How does Nagel’s skeptical challenge undermine ordinary claims to knowledge, and why does he think these doubts are difficult to answer conclusively? Do you find skepticism compelling, or do you think we are justified in trusting our senses and reasoning despite the lack of absolute proof? In your reflection, discuss at least one everyday belief (for example, that other people exist, that the past is real, or that the physical world continues when you are not looking) and analyze how Nagel’s arguments put that belief into question. Then explain how you respond to this skeptical challenge: should we demand certainty for knowledge, or is a weaker standard enough? Conclude by evaluating whether Nagel helps us better understand the limits of human knowledge, even if skepticism cannot be fully resolved.
