* Kim, Scott E. "The Impossible Skew Quadrilateral: A Four-Dimensional Optical Illusion". In David Brisson, ed. Proceedings of the 1978 A.A.A.S. Sym osium on Hypergraphics: Visualizing Complex Relationships in Art and Science. Boulder, Colo.: Westview Press, 1978. What seems at first an inconceivably hard idea-an optical illusion for four-dimensional "people"-is gradually made crystal clear, in an amazing virtuoso presentation utilizing a long series of excellently executed diagrams. The form of this article is just as intriguing and unusual as its content: it is tripartite on many levels simultaneously. This article and my book developed in parallel and each stimulated the other.

Kleene, Stephen C. Introduction to Mathematical Logic. New York: John Wiley, 1967. A thorough, thoughtful text by an important figure in the subject. Very worthwhile. Each time I reread a passage, I find something new in it which had escaped me before.

. Introduction to Metamathematics. Princeton: D. Van Nostrand (1952). Classic work on mathematical logic; his textbook (above) is essentially an abridged version. Rigorous and complete, but oldish.

Kneebone G. J. Mathematical Logic and the Foundations of Mathematics. New York: Van Nostrand Reinhold, 1963. A solid book with much philosophical discussion of such topics as intuitionism, and the "reality" of the natural numbers, etc.

Koestler, Arthur. The Act of Creation, New York: Dell, 1966. Paperback. A wide-ranging and generally stimulating theory about how ideas are "bisociated" to yield novelty. Best to open it at random and read, rather than begin at the beginning.

Koestler, Arthur and J. R. Smythies, eds. Beyond Reductionism. Boston: Beacon Press, 1969. Paperback. Proceedings of Yr conference whose participants all were of the opinion that biological systems cannot be explained reductionistically, and that there is something "emergent" about life. I am intrigued by books which seem wrong to me, yet in a hard-to-pin-down way.

** Kutbose, Gyomay. Zen Koans. Chicago: Regnerv, 1973. Paperback. One of the best collections of koans available. Attractively presented- An essential book for any Zen library. Kuffler, Stephen W. and John G. Nicholls. From Neuron to Brain. Sunderland, deals Mss.: Smauer Associates, 1976. Paperback. A book which, despite its title, deals mostly with microscopic processes in the brain, and quite little with the way people's thoughts come out of the tangled mess. The work of Hubel and Wiesel on visual systems is covered particularly well.

metamathematics. Worth studying. Latos Imre. Proofs and Refutations. New York: Cambridge University Press, 1976. Paperback. A most entertaining book in dialogue form, discussing how concepts are formed in mathematics. Valuable not only to mathematicians, but also to people interested in thought processes.

** Lehninger, Albert. Biochemistry. New York: Worth Publishers, 1976. A wonderfully readable text, considering its technical level. In this book one can find many ways in which proteins and genes are tangled together. Well organized, and exciting.

** Lucas, J. R. "Minds, Machines, and Godel". Philosophy 36 (1961): 112. This article is reprinted in Anderson's Minds and Machines, and in Sayre and Crosson's The Modeling of Mind. A highly controversial and provocative article, it claims to show that the human brain cannot, in principle, be modeled by a computer program. The argument is based entirely on Godel's Incompleteness Theorem, and is a fascinating one. The prose is (to my mind)

incredibly infuriating-vet for that very reason, it makes humorous reading. "Satan Stultified: A Rejoinder to Paul Benacerraf". Monist 52 (1968): 145.

Anti-Benacerraf argument, written in hilariously learned style: at one point Lucas refers to Benacerraf as "self-stultifyingly eristic" (whatever that means). The Lucas-Benacerraf battle, like the Lucas-Good battle, offers much food for thought.

. "Human and Machine Logic: A Rejoinder". British Journal for the Philosophy of Science 19 (1967): 155. An attempted refutation of Good's attempted refutation of Lucas' original article.

** MacGillavry, Caroline H. Symmetry Aspects of the Periodic Drawings of M. C.

Escher. Utrecht: A. Oosthoek's Uitgevermaatschappij, 1965. A collection of tilings of the plane by Escher, with scientific commentary by a crystallographer. The source for some of my illustrations-e.g., the Ant Fugue and the Crab Canon. Reissued in 1976 in New York by Harry N. Abrams under the title Fantasy and Symmetry.

MacKay, Donald M. Information, Mechanism and Meaning. Cambridge, Mass.: M.I.T.

Press, 1970. Paperback. A book about different measures of information, applicable in different situations; theoretical issues related to human perception and understanding; and the way in which conscious activity can arise from a mechanistic underpinning.

• Mandelbrot, Benoit. Fractals: Form, Chance, and Dimension. San Francisco: W. H.

Freeman, 1977. A rarity: a picture book of sophisticated contemporary research ideas in mathematics. Here, it concerns recursively defined curves and shapes, whose dimensionality is not a whole number. Amazingly, Mandelbrot shows their relevance to practically every branch of science.

• McCarthy, John. "Ascribing Mental Qualities to Machines". To appear in Martin Ringle, ed. Philosophical Perspectives in Artificial Intelligence. New York: Humanities Press, 1979. A penetrating article about the circumstances under which it would make sense to say that a machine had beliefs, desires, intentions, consciousness, or free will.

It is interesting to compare this article with the book by Griffin.

Meschkowski, Herbert. Non-Euclidean Geometry. New York: Academic Press, 1964.

Paperback. A short book with good historical commentary.

Meyer, Leonard B. Emotion and Meaning in Music. Chicago: University of' Chicago Press, 1956. Paperback. A book which attempts to use ideas of Gestalt svcholo theory of perception to explain why musical structure is as it is. One of the more unusual the books on music and mind.

. Music, The Arts, and Ideas. Chicago: University of Chicago Press, 1967. Paperback. A thoughtful analysis of mental processes involved in listening to music, and of hierarchical structures in music. The author compares modern trends in music with Zen Buddhism.

Miller, G. A. and P. N. joint son-Laird. Language and Perception- Cambridge, Mass.: Harvard University Press, Belknap Press, 1976. A fascinating compendium of linguistic facts and theories, hearing on Whorl 's hypothesis that language is the same as worldviesv. A typical example is the discussion of the weird "mother-in-law" language of the Dyirbal people of Northern Queensland: a separate language used only for speaking to one's mother-in-law.

Minsky, Marvin L. "Matter, Mind, and Models". In Marvin L. Minskv, ed. Son antic Information Processing. Cambridge, Mass.: M.I.T. Press, 1968.

Cambridge, Mass.: M.I.T. Artificial Intelligence Laboratory, Al Memo 252, 1972. A survey of all the work in Artificial Intelligence done at M.I.T. up to 1972, relating it to psychology and epistemology. Could serve excellently as an introduction to Al.

Monod, Jacques. Chance and Necessity. New York: Random House, Vintage Books, 1971. Paperback. An extremel fertile mind writing in an idiosyncratic way about fascinating questions, such as how life is constructed out of non-life: how evolution, seeming_ to violate the second law of thermodynamics, is actually dependent on it. The book excited me deeply.

A large fraction of Babbage's autobiography is reprinted here, along with several articles about Babbage's machines and his "Mechanical Notation".

Mvhill, John. "Some Philosophical Implications of Mathematical Logic". Review of Metaphysics 6 (1952): 165. An unusual discussion of ways in which Godel's Theorem and Church's Theorem are connected to psychology and epistemology. Ends up in a discussion of beauty and creativity.

Nagel, Ernest. The Structure of Science. New York: Harcourt, Brace, and World, 1961. A classic in the philosophy of science, featuring clear discussions of reductionism vs.

holism, teleological vs. nonteleological explanations, etc.

Nagel, Ernest and James R. Newman. Godel's Proof. New York: New York University Press, 1958. Paperback. An enjoyable and exciting presentation, which was, in many ways, the inspiration for my own book.

An odd but charming book.
