Daniel Dennett examines the different elements that make up what we call 'minds' What kinds of minds are there, and how do we know? The first question is about what exists and the second is about our knowledge. The aim of Kinds of Minds is to answer these questions, in general outline, and to show why these two questions have to be answered together. What exists is one thing. What we can know about is something else. But we know enough about minds, Dennett argues, to know that one of the things that makes them different from everything else in the universe is the way we know about them.
