Brute ignorance

Abstract We know a lot about what the world is like. We know less, it seems, about what we know about what the world is like. According to a common thought, it is easier for us to come to know about the state of the world than to come to know about the state of our own knowledge. What explains this gap? An attractively simple hypothesis is that our ignorance about what we know is explained by our ignorance about the world. There are things we fail to know about what we know about the world because there are things we fail to know about the world. This hypothesis is often motivated by the idea that knowledge requires a margin‐for‐error. In this paper, I'll argue that this simple hypothesis is inadequate. Not all our ignorance of our knowledge can be explained by our ignorance about the world. In this sense, at least some of our ignorance about what we know is brute.
