An Enquiry Concerning Human Understanding, first published in 1748, is David Hume’s seminal philosophical work on the limits of human knowledge. Through clear and accessible prose, Hume challenges assumptions about causality, religion, and empirical reasoning. His skeptical inquiry into the nature of experience and belief laid the foundation for modern empiricism and has had a profound impact on philosophy, particularly in epistemology and metaphysics. Hume’s arguments continue to provoke discussion and debate among philosophers today.
