"The Enquiry Concerning Human Understanding" is a philosophical work by David Hume, published in 1748. It explores the nature of human cognition, emphasizing the limits of human knowledge and the role of experience in shaping our understanding of the world. Hume argues that our beliefs are often based on habit rather than rational justification. The text also introduces the concept of empiricism, which asserts that knowledge comes primarily from sensory experience. Hume critiques the notion of causation, suggesting that we cannot directly observe causal connections, but instead infer them from patterns in our experiences. This work significantly influenced modern philosophy and the development of the scientific method.
