A central theme of this book is that the main problems of philosophy and certainly the main traditional problems in the theory of knowledge, concern the space between language and the world. Professor Danto distinguishes between descriptive concepts, concerned with saying how the world is and semantic concepts, which have to do with the application of descriptions of the world. Failure to make these distinctions is responsible for a class of seemingly irresolvable disputes over the foundations of knowledge; but when the distinction is appreciated, a plausible philosophical theory of what it is to know the world can be framed which is free from the standard scepticisms.
Arthur C. Danto was Johnsonian Professor Emeritus of Philosophy at Columbia University and art critic for The Nation. He was the author of numerous books, including Unnatural Wonders: Essays from the Gap Between Art and Life, After the End of Art, and Beyond the Brillo Box: The Visual Arts in Post-Historical Perspective.
