From the reviews: "This book comprises a very broad and interesting collection of extended versions of papers from the 2011 conference on Philosophy and Theory of Artificial Intelligence. ... this book would be a valuable reference for researchers not only from AI and philosophy, but also those working in the vast number of disciplines that influence their development. The philosophical nature of the discussions should appeal to anyone interested in the big picture of where the discipline is headed." (Gerardo Simari, ACM Computing Reviews, December, 2012)
