There is no problem more important, or more daunting, than discovering the structure and processes behind human thought. What is Thought? is an important step towards finding the answer. A concise summary of the progress and pitfalls to date gives the reader the context necessary to appreciate Baum's important insights into the nature of cognition.

A major work. Berger offers an elegant examination of issues that have been in controversy for the last forty years and that have been and are being discussed by the best philosophers of language. But where others have tended to offer piecemeal solutions, Berger offers a unified account based on a small set of principles.

A book that is admirable as much for its candor as its ambition.... If What is Thought? can inspire a new generation of computer scientists to inquire anew about the nature of thought, it will be a valuable contribution indeed.

... [Should] engage general readers who wish to enjoy a clear, understandable description of many advanced principles of computer science.

Eric Baum's book is a remarkable achievement. He presents a novel thesis—that the mind is a program whose components are semantically meaningful modules—and explores it with a rich array of evidence drawn from a variety of fields. Baum's argument depends on much of the intellectual core of computer science, and as a result the book can also serve as a short course in computer science for non-specialists. To top it off, What is Thought? is beautifully written and will be at least as clear and accessible to the intelligent lay public as Scientific American.

In his enjoyable and informative book The Evolution of Morality, Richard Joyce distinguishes between explaining how natural selection might explain socially useful behavior in animals and what more is needed to explain morality, with its thoughts about right or wrong, in human beings. Contrary to what others have said, Joyce argues plausibly that, to the extent that our moral concepts and opinions are the results of natural selection, there is no rational basis for these concepts and opinions.
