What if the world you see and touch cannot exist apart from a mind?

In A Treatise Concerning the Principles of Human Knowledge, George Berkeley challenges the idea of matter beneath everything we perceive. He argues that what exists is minds and the ideas they perceive. His starting point is simple, but the stakes are large: what can we know about the world, and what do we mean when we call something real?

Berkeley sees the new science and John Locke’s philosophy as paths toward doubt about the world and God. His answer unfolds in short, numbered sections. He attacks abstract ideas, questions the qualities we assign to objects, and asks whether matter explains anything at all. According to Berkeley, active spirits, rather than matter, cause the ideas we perceive.
