A Treatise Concerning the Principles of Human Knowledge

George Berkeley · philosophy, 1710 · Philosophy
  • He blames philosophy's confusion on a bad mental habit, not weak minds. In the Introduction, Berkeley says the mind's trouble comes from framing "abstract ideas," like a colour that is "neither red, nor blue, nor white," and then wondering why reasoning collapses into paradox.
  • An apple, he says, is nothing but a bundle of sensations. A colour, taste, smell, figure, and consistence "having been observed to go together, are accounted one distinct thing, signified by the name APPLE." Strip away the sensations and nothing is left to call a fruit.
  • He compresses his whole system into three Latin words. Section 3 states it directly: "their esse is percipi," their being is their being perceived. The table exists, he says, only in the sense that he sees and feels it, or that some other mind does.
  • He dares you to imagine an unperceived tree, then catches you in the act. Picture "trees in a park" with nobody there to see them, he says, then points out the trap: forming that mental picture is itself an act of perceiving, so the unperceived tree was never actually conceived.
  • He argues God is more evident to us than other people are. Since most of our sensations obviously do not come from our own wills, Berkeley concludes some other Spirit must be producing them directly, and calls that Spirit's effects on our senses more constant and convincing than any evidence we have for other minds.
  • He admits the whole book is pointless without a religious payoff. He closes by saying the treatise is worthless to him unless it leaves readers with "a pious sense of the Presence of God" and steers them toward what he calls "the salutary truths of the Gospel."

Why it earns a slot: Why it earns a slot: it pushes empiricism to its most unsettling endpoint, if all we ever access is sensation, matter itself becomes an unnecessary hypothesis, a conclusion physicists would circle back to two centuries later when they started asking what observation does to reality.
