Douglas Hofstadter's new book is called Fluid Concepts and Creative Analogies:
Computer Models of the Fundamental Mechanisms of Thought.
His first two books, Goedel, Escher, Bach and Metamagical Themas discussed a number
of ideas relevant to artificial intelligence and cognitive science, such as recursivity
and emergent behavior, but this new book looks back from the perspective of having grappled
with those ideas in the course of implementing actual computer models. Programs that model
creativity and analogy-making have been designed by Doug and his graduate students, and the
story of their past, present and future development is the subject of the book, co-authored
by the students in the Fluid Analogies Research Group (FARG). There is an incredible wealth of
information in this book.There is a 1995 review of the book at Byte Magazine's online archive which provides a little more background.
The fancy font used for the capital letters in the title (FCCA) is, by the way, Magnificat.
