Bibliography

The presence of two asterisks indicates that the hook or article was a prime motivator of my book. The presence of a single asterisk means that the book or article has some special feature or quirk which I want to single out.

I have not given many direct pointers into technical literature; instead I have chosen to give "meta-pointers": pointers to books which have pointers to technical literature.

Allen, John. The Anatomy of LISP. New York: McGraw-Hill, 1978. The most comprehensive book on LISP, the computer language which has dominated Artificial Intelligence research for two decades. Clear and crisp.

Anderson, Alan Ross, ed. Minds and Machines. Englewood Cliffs, N. J.: PrenticeHall, 1964. Paperback. A collection of provocative articles for and against Artificial Intelligence. Included are Turing's famous article "Computing Machines and Intelligence" and Lucas' exasperating article "Minds, Machines, and Godel".

Babbage, Charles. Passages from the Life of a Philosopher. London: Longman, Green, 1864. Reprinted in 1968 by Dawsons of Pall Mall (London). A rambling selection of events and musings in the life of this little-understood genius. There's even a play starring Turnstile, a retired philosopher turned politician, whose favorite musical instrument is the barrel-organ. I find it quite jolly reading.

Baker, Adolph. Modern Physics and Anti-physics. Reading, Mass.: Addison-Wesley, 1970. Paperback. A book on modern physics-especially quantum mechanics and relativity-whose unusual feature is a set of dialogues between a "Poet" (an antiscience

"freak") and a "Physicist". These dialogues illustrate the strange problems which arise when one person uses logical thinking in defense of itself while another turns logic against itself.

Ball, W. W. Rouse. "Calculating Prodigies", in James R. Newman, ed. The World of Mathematics, Vol. 1. New York: Simon and Schuster, 1956. Intriguing descriptions of several different people with amazing abilities that rival computing machines.

Barker, Stephen F. Philosophy of Mathematics. Englewood Cliffs, N. J.: Prentice-Hall.

1969. A short paperback which discusses Euclidean and non-Euclidean geometry, and then Godel's Theorem and related results without any mathematical forms lism.

* Beckmann, Petr. A History of Pi. New York: St. Martin's Press, 1976. Paperback.

Actually, a history of the world, with pi as its focus. Most entertaining, as well as a useful reference on the history of mathematics.

* Bell, Eric Temple. Men of Mathematics. New York: Simon & Schuster, 1965.

Paperback. Perhaps the most romantic writer of all time on the history of mathematics.

He makes every life story read like a short novel. Nonmathematicians can come away with a true sense of the power, beauty, and meaning of mathematics.

Benacerraf, Paul. "God, the Devil, and Godel". Monist 51 (1967): 9. One of the most important of the many attempts at refutation of Lucas. All about mechanism and metaphysics, in the light of Godel's work.

Benacerraf, Paul, and Hilary Putnam. Philosophy of Mathematics-Selected Readings.

Englewood Cliffs, N. J.: Prentice-Hall, 1964. Articles by Godel, Russell, Nagel, von Index

Neumann, Brouwer, Frege, Hilbert, Poincare, Wittgenstein, Carnap, Quine, and others on the reality of numbers and sets, the nature of mathematical truth, and so on.

* Bergerson, Howard. Palindromes and Anagrams. New York: Dover Publications, 1973.

Paperback. An incredible collection of some of the most bizarre and unbelievable wordplay in English. Palindromic poems, plays, stories, and so on.

Bobrow, D. G., and Allan Collins, eds. Representation and Understanding: Studies in Cognitive Science. New York: Academic Press, 1975. Various experts on Artificial Intelligence thrash about, debating the nature of the elusive "frames", the question of procedural vs. declarative representation of knowledge, and so on. In a way, this book marks the start of a new era of Al: the era of representation.

* Boden, Margaret. Artificial Intelligence and Natural Man. New York: Basic Books, 1977. The best hook I have ever seen on nearly all aspects of Artificial Intelligence, including technical questions, philosophical questions, etc. It is a rich book, and in niv opinion, a classic. Continues the British tradition of clear thinking and expression on matters of mind, free will, etc. Also contains an extensive technical bibliography.

. Purposive Explanation in Psychology. Cambridge, Mass.: Harvard University Press, 1972. The book to which her Al book is merely- "an extended footnote", says Boden.

* Boeke, Kees. Cosmic View: The Universe in 40 Jumps. New York: John Day, 1957.

The ultimate book on levels of description. Everyone should see this book at some point in their life. Suitable for children.

** Bongard, M. Pattern Recognition. Rochelle Park, N. J.: Hay den Book Co., Spartan Books, 1970. The author is concerned with problems of determining categories in an ill-defined space. In his book, he sets forth a magnificent collection of 100 "Bongard problems" (as I call them)-puzzles for a pattern recognizer (human or machine) to test its wits on. They are invaluably stimulating for anyone whoo is interested in the nature of intelligence.

Boolos, George S., and Richard Jeffrey. Computability and Logic. New York: Cambridge University Press. 1974. A sequel to Jeffrey's Formal Logic. It contains a wide number of results not easily obtainable elsewhere. Quite rigorous, but this does not impair its readability.

Carroll, John B., Peter Davies, and Barry Rickman. The American Heritage Word Frequency Book. Boston: Houghton Mifflin, and New York: American Heritage Publishing Co., 1971. A table of words in order of frequency in modern written American English. Perusing it reseals fascinating things about out- thought processes.

Cerf, Vinton. "Parry Encounters the Doctor". Datamation, July 1973, pp. 62-64. The first meeting of artificial "minds"-what a shock!

Chadwick, John. The Decipherment of Linear B. New York: Cambridge University Press, 1958. Paperback. A book about a classic decipherment-that of a script from the island of Crete-done by a single man: Michael Ventris.

Chaitin, Gregory J. "Randomness and Mathematical Proof"'. Scientific American, May 1975. An article about an algorithmic definition of randomness, and its intimate relation to simplicity. These two concepts are tied in with Godel's Theorem, which assumes a new meaning. An important article.

Cohen, Paul C. Set Theory and the Continuum Hypothesis. Menlo Park, Calif.: W. A.

Benjamin, 1966. Paperback. A great contribution to modern mathematics-the demonstration that various statements are undecidable within the usual formalisms for Index

set theory-is here explained to nonspecialists by its discoverer. The necessary prerequisites in mathematical logic are quickly, concisely, and quite clearly presented.

Cooke, Deryck. The Language of Music. New York: Oxford University Press, 1959.

Paperback. The only book that I know which tries to draw an explicit connection between elements of music and elements of human emotion. A valuable start down what is sure to be a long hard road to understanding music and the human mind.

* David, Hans Theodore.J. S. Bach's Musical Offering. New York: Dover Publications, 1972. Paperback. Subtitled "History, Interpretation, and Analysis". A wealth of information about this tour de force by Bach. Attractively written.

** David, Hans Theodore, and Arthur Mendel. The Bach Reader. New York: W. W.

Norton, 1966. Paperback. An excellent annotated collection of original source material on Bach's life, containing pictures, reproductions of manuscript pages, many short quotes from contemporaries, anecdotes, etc., etc.
