  2. Martin Zwick, Dialectics and Catastrophe.
    The Catastrophe Theory of Rene Thorn and E. C. Zeeman' suggests a mathematical interpretation of certain aspects of Hegelian and Marxist dialectics. Specifically, the three 'classical' dialectical principles, (1) the transformation of quantity into quality, (2) the unity and struggle of opposites, and (3) the negation of negation, can be modeled with the seven 'elementary catastrophes' given by Thorn, especially the catastrophes known as the 'cusp' and the 'butterfly'. Far from being empty metaphysics or scholasticism, as critics have argued, the (...)

  3. Jim Marsh, Martin Zwick & Byrne Lovell, Global Optimization Studies on the 1-D Phase Problem.
    The Genetic Algorithm (GA) and Simulated Annealing (SA), two techniques for global optimization, were applied to a reduced (simplified) form of the phase problem (RPP) in computational crystallography. Results were compared with those of "enhanced pair flipping" (EPF), a more elaborate problem-specific algorithm incorporating local and global searches. Not surprisingly, EPF did better than the GA or SA approaches, but the existence of GA and SA techniques more advanced than those used in this study suggest that these techniques still hold (...)

  4. Martin Zwick, Towards an Ontology of Problems.
    Systems theory o ers a language in which one might formulate a metaphysics { or more speci cally an ontology { of problems. This proposal is based upon a conception of systems theory shared by von Bertalan y, Wiener, Boulding, Rapoport, Ashby, Klir, and others,and expressedsuccinctlyby Bunge, who consideredgame theory, information theory, feedback control theory, and the like to be attempts to construct an \exact and scienti c metaphysics." Our prevailing conceptions of \problems" are concretized yet also fragmented and in (...)

  5. Martin Zwick, Understanding Imperfection.
    In this talk, I want to present a conception that I have been working on for a number of years (Zwick, 1983, 1995) about the use of systems ideas. I start from the negative and proceed to the positive. The negative assertion is that systems ideas by themselves , unsupplemented by more specific and concrete knowledge (e.g., from the various disciplines), are insufficient for practical application, either for obtaining knowledge about the world or for solving problems. The reason for this (...)

  6. Martin Zwick & Jeffrey A. Fletcher (2013). Levels of Altruism. Biological Theory 9 (1):1-8.
    The phenomenon of altruism extends from the biological realm to the human sociocultural realm. This article sketches a coherent outline of multiple types of altruism of progressively increasing scope that span these two realms and are grounded in an ever-expanding sense of “self.” Discussion of this framework notes difficulties associated with altruism at different levels. It links scientific ideas about the evolution of cooperation and about hierarchical order to perennial philosophical and religious concerns. It offers a conceptual background for inquiry (...)
