"An Enquiry Concerning Human Understanding" is a philosophical work by David Hume, published in 1748. In this text, Hume explores the nature of human cognition, emphasizing the limits of human knowledge and the role of experience in shaping our understanding of the world. He argues that our beliefs are often based on habit rather than rational justification. Hume also critiques the concept of causation, suggesting that we cannot directly observe causal connections but instead infer them from patterns of experience. This work laid the groundwork for later philosophical discussions on empiricism and skepticism, influencing thinkers such as Immanuel Kant and the development of modern philosophy.
