A Treatise Concerning the Principles of Human Knowledge

First published in 1710, George Berkeley's A Treatise Concerning the Principles of Human Knowledge establishes a foundational perspective in Empiricist philosophy by claiming that the physical world exists solely as ideas within the mind. This groundbreaking work positioned Berkeley as the founder of the immaterialist school of thought, influencing later philosophers like David Hume and Immanuel Kant, and continues to provoke discussion in various fields, including mathematics and metaphysics.
