A Treatise Concerning the Principles of Human Knowledge

Exploring the nature of reality and perception, this work delves into the philosophical arguments that challenge materialism. Berkeley posits that objects only exist as they are perceived, emphasizing the role of the mind in shaping our understanding of the world. He critiques the idea of substance independent of perception and introduces the concept of immaterialism, suggesting that reality is fundamentally tied to the experiences of conscious beings. This treatise is a foundational text in the study of philosophy and epistemology.
