'Catastrophe theory (CT), as a new field in mathematics with many possible ramifications for both the physical and biological sciences, has recently been the subject of much controversy (see [1]-[5]). This controversy, in this reviewer's opinion, has served a valuable purpose insofar as it has stimulated the theory's proponents to refine and delineate their concepts more clearly. Catastrophe theory was developed by the Field prize winner, Rene Thom; but much work has been accomplished by E. C. Zeeman and his group, especially with respect to applications.' pp.609-610. IEEE TRANSACTIONS ON SYSTEMS, MAN, AND CYBERNETICS, VOL. SMC-9, NO. 9, SEPTEMBER 1979. https://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=4310286
'To write a review in this environment has a very personal side for me. On one hand my own work on dynamical systems is closely connected to the origins of CT. I have had a long and close personal and professional relationship with both Thorn and Zeeman. More than 20 years ago I was discussing singularities of maps, transversality, and immersions with René Thom. Thom tried to interest me in an early draft of chapters of his book Structural stability and morphogenesis in 1966.
On the other hand I have remained skeptical and aloof from CT, perhaps due to my conservatism in science. While my colleagues and students were showing enthusiasm for CT, I gave critical lectures, one at the University of Chicago in 1974, one at the Aspen Institute of Physics in 1975. More recently I have been quoted negatively in the "Science" and New York Times references above. This is the first time I have written on the subject, and I should warn the reader of this negative bias, far from shared by many of my fellow mathematicians.' p.1360.
Some defenders of CT may accuse me of discussing very special examples not characteristic of the literature of the subject. I feel that the problem of lack of justification discussed above, is also found in Zeeman's other models. Furthermore Thorn's models are even less specific and less developed. On the other hand, Thorn's work in CT covers many subjects; in this connection Zeeman writes in his Scientific American article, April 1976, p. 65: "The method has the potential for describing the evolution of form in all aspects of nature, and hence it embodies a theory of great generality."' p.1366.
