32Saving the distinctions: Distinctions as the epistemologically significant content of experienceIn M. E. Reicher & J. C. Marek (eds.), Experience and Analysis: Papers of the 27th International Wittgenstein Symposium, Austrian Ludwig Wittgenstein Society. 2004.To account for a perceived distinction it is necessary to postulate a real distinction. Our process of experiencing the world is one of, mostly unconscious, interpretation of observed distinctions to provide us with a partial world-picture that is sufficient to guide action. The distinctions, themselves, are acorrigible (they do not have a truth value), directly perceived, structured, and capable of being interpreted. Interpreted experience is corrigible, representational and capable of guiding …Read more

Progress in Scientific Revolutions: The Problem of Semantic IncommensurabilityDissertation, The University of Western Ontario (Canada). 1984.If two successive theories are semantically incommensurable, we have no way to make a complete comparison of their contents. If so, we have no way to verify that the highly confirmed content of the successor is greater than that of its predecessor, and we cannot verify that scientific knowledge has accumulated across the theory change. Thus, incommensurability creates a problem for the justification of the standard cumulative conception of scientific progress. ;To resolve this problem, I disting…Read more

4Every manifestation of information, semiosis and meaning we have been able to study experimentally has a physical form. Neglect of their dynamical (energetic) ground tends towards dualism or idealism, leaving the causal basis of semiosis and the causal powers of representations mysterious. Consideration of the necessary physical requirements for the embodiment of semiotic categories imposes a discipline on semiotics required for its integration into the rest of science, especially for the emergi…Read more

16A Dynamical Account of EmergenceCybernetics and Human Knowing 15 (3-4): 75-86. 2008.Emergence has traditionally been described as satisfying specific properties, notably nonreducibility of the emergent object or properties to their substrate, novelty, and unpredictability from the properties of the substrate. Sometimes more mysterious properties such as independence from the substrate, separate substances and teleological properties are invoked. I will argue that the latter are both unnecessary and unwarranted. The descriptive properties can be analyzed in more detail in logica…Read more

107Prospects for Reconciling Sellars' World ImagesSouth African Journal of Philosophy 29 (4): 343-356. 2010.Almost fifty years ago Wilfrid Sellars described two competing ways of imagining the world, the Manifest Image and the Scientific Image. The Manifest Image is an idealization of common sense aided by critical philosophy, whereas the Scientific Image is the product of our best science. The methodologies of the two images are very different: the Manifest Image deals with experience and looks only at relations among bits of experience and analysis of experience into the relations that must lie behi…Read more

212Holism and Emergence: Dynamical Complexity Defeats Laplace’s DemonSouth African Journal of Philosophy 30 (2): 229-243. 2011.The paradigm of Laplacean determinism combines three regulative principles: determinism, predictability, and the explanatory adequacy of universal laws together with purely local conditions. Historically, it applied to celestial mechanics, but it has been expanded into an ideal for scientific theories whose cogency is often not questioned. Laplace’s demon is an idealization of mechanistic scientific method. Its principles together imply reducibility, and rule out holism and emergence. I will arg…Read more

78Evolutionary Moral RealismRoutledge. 2019.Against standard approaches to evolution and ethics, this book develops the idea that moral values may find their origin in regularly recurring features in the cooperative environments of species of organisms that are social and intelligent. Across a wide range of species that are social and intelligent, possibilities arise for helping others, responding empathetically to the needs of others, and playing fairly. The book identifies these underlying environmental regularities as biological natura…Read more

218A system is autonomous if it uses its own information to modify itself and its environment to enhance its survival, responding to both environmental and internal stimuli to modify its basic functions to increase its viability. Autonomy is the foundation of functionality, intentionality and meaning. Autonomous systems accommodate the unexpected through self-organizing processes, together with some constraints that maintain autonomy. Early versions of autonomy, such as autopoiesis and closure to e…Read more

76Pragmatic IncommensurabilityPSA: Proceedings of the Biennial Meeting of the Philosophy of Science Association 1984 146-153. 1984.Kuhn's incommensurability thesis has generally been interpreted by friends and foes alike so as to preclude direct rational communication across revolutionary divides in science. In this paper, a weaker form of incommensurability is sketched which allows eventual comparison of incommensurable theories, but is consistent with Kuhn's model of science. Incommensurability occurs whenever the knowledge or ability to translate from the language of one theory to that of another is lacking. It can be re…Read more

33Goodman’s account of the ‘grue’ paradox stands at a crossroads in the history of twentieth century epistemology. Published in 1954, Fact, Fiction, and Forecast is a reaction to the logical empiricist views that held sway in the first half of the last century and anticipates many of the conventionalist and/or relativist moves popular throughout the second half. Through his evaluation of Hume’s problem of induction, as well as his own novel reformulation of it, Goodman comes to reject a number of …Read more

17Wilfrid Sellars described his Manifest Image and Scientific Image as idealizations of our common sense and scientific views of the world, including our own special role in the world as humans. If, as Sellars suggested, there is an irreconcilable conflict between these images, it may not be possible to reconcile science with common sense. The Scientific Image, as we have inherited it, has a strong reductionist element that seems to imply that things are not really as they appear to common sense. …Read more

165Entropy in evolutionBiology and Philosophy 1 (1): 5-24. 1986.Daniel R. Brooks and E. O. Wiley have proposed a theory of evolution in which fitness is merely a rate determining factor. Evolution is driven by non-equilibrium processes which increase the entropy and information content of species together. Evolution can occur without environmental selection, since increased complexity and organization result from the likely capture at the species level of random variations produced at the chemical level. Speciation can occur as the result of variation within…Read more

167After the fall: Religious capacities and the error theory of moralityBehavioral and Brain Sciences 27 (6): 751-752. 2004.The target article proposes an error theory for religious belief. In contrast, moral beliefs are typically not counterintuitive, and some moral cognition and motivation is functional. Error theories for moral belief try to reduce morality to nonmoral psychological capacities because objective moral beliefs seem too fragile in a competitive environment. An error theory for religious belief makes this unnecessary.

92Supervenience and Reduction in Biological HierarchiesCanadian Journal of Philosophy, Supplementary Volume 14 (n/a): 209-234. 1988.Supervenience is a relationship which has been used recently to explain the physical determination of biological phenomena despite resistance to reduction. Supervenience, however, is plagued by ambiguities which weaken its explanatory value and obscure some interesting aspects of reduction in biology. Although I suspect that similar considerations affect the use of supervenience in ethics and the philosophy of mind, I don’t intend anything I have to say here to apply outside of the physical and …Read more

2Rhythmic entrainment is the formation of regular, predictable patterns in time and/or space through interactions within or between systems that manifest potential symmetries. We contend that this process is a major source of symmetries in specific systems, whether passive physical systems or active adaptive and/or voluntary/intentional systems, except that active systems have more control over accepting or avoiding rhythmic entrainment. The result of rhythmic entrainment is a simplification of t…Read more
