- David L. Hull (1988). A Mechanism and its Metaphysics: An Evolutionary Account of the Social and Conceptual Development of Science. Biology and Philosophy 3 (2).The claim that conceptual systems change is a platitude. That our conceptual systems are theory-laden is no less platitudinous. Given evolutionary theory, biologists are led to divide up the living world into genes, organisms, species, etc. in a particular way. No theory-neutral individuation of individuals or partitioning of these individuals into natural kinds is possible. Parallel observations should hold for philosophical theories about scientific theories. In this paper I summarize a theory of scientific change which I set out in considerable detail in a book that I shall publish in the near future. Just as few scientists were willing to entertain the view that species evolve in the absence of a mechanism capable of explaining this change, so philosophers should be just as reticent about accepting a parallel view of conceptual systems in science evolving in the absence of a mechanism to explain this evolution. In this paper I set out such a mechanism. One reason that this task has seemed so formidable in the past is that we have all construed conceptual systems inappropriately. If we are to understand the evolution of conceptual systems in science, we must interpret them as forming lineages related by descent. In my theory, the notion of a family resemblance is taken literally, not metaphorically. In my book, I set out data to show that the mechanism which I propose is actually operative. In this paper, such data is assumed.Reading list | Discuss | Edit | Categorize |My bibliography

The fundamental dialectic of Science as a Process is the interaction between two narrative levels. At one level, the book is a historical narrative of one aspect of one ongoing problem in systematics. At the second level, Hull presents a theoretical model of the scientific process which draws heavily on invoked similarities between biological and scientific change. I first situate the model as one alternative among several which loosely fit under the umbrella of 'evolutionary epistemologies.' Second, I explore one of the implications of Hull's model, namely, that insofar as scientific theories are [parts of] "conceptual lineages," they are "conceptual individuals.".

Conceptual Systems explores how these new concepts are entered into our systems along with sufficient continuity with older ideas to ensure understanding. The encyclopaedic breadth of this text highlights the many different aspects and disciplines that together present an insightful view into the various theories of concepts. Harold Brown, a reputable author in the philosophy of science examines several historically influential theories of concepts as well as providing a clear view on the general theory of conceptual change. Interesting case studies examine examples of conceptual change in the history of physics including the move in seventeenth century physics from Galileo to Descates to Newton; and the conceptual framework of the "standard model" in the late twentieth century high- energy physics. The key central themes in the philosophy of science that are explored in- depth in this enormous book make it an essential read for academics in this field.

We show that the changes characteristic of scientific revolutions, especially taxonomic changes, can occur in a continuous manner. Using the frame model of concept representation to capture structural relations within concepts and the direct links between concept and taxonomy, we develop an account of conceptual change in science that more adequately reflects the current understanding that episodes like the Copernican revolution are not always abrupt. When concepts are represented by frames, the transformation from one taxonomy to another can be achieved in a piecemeal fashion not preconditioned by a crisis stage, and a new taxonomy can arise naturally out of the old frame instead of emerging separately from the existing conceptual system. This cognitive mechanism of continuous change demonstrates the constructive roles of anomaly and incommensurability in promoting the progress of science.

The notion of development has been permeated by concepts and methods from positivistic science. As a result, many development initiatives are reductionistic, myopic, and with little or impact on the improvement of the quality of life and the sustainability of communities and societies. This article marks the beginning of a transdisciplinary inquiry among the authors, motivated by direct interest in the issue of development, per se, and in particular, Mexico's development. Our inquiry departs from and weaves together our various areas of expertise and experience, including: systems theory, general evolution theory, economic development, technology transfer, social innovation, sustainable development, environmental behavior, social systems design, and education. The article reviews the concept of development from an evolutionary and systemic perspective. It outlines the foundations of evolutionary development in terms of theory, philosophy, and methodology and provides a conceptual framework for future research aimed at the articulation of a practical model for evolutionary development.

One of the principal difficulties in assessing Science as aProcess (Hull 1988) is determining the relationship between the various elements of Hull's theory. In particular, it is hard to understand precisely how conceptual selection is related to Hull's account of the social dynamics of science. This essay aims to clarify the relation between these aspects of his theory by examining his discussion of the``demic structure'' of science. I conclude that the social account cando significant explanatory work independently of the selectionistaccount. Further, I maintain that Hull's treatment of the demicstructure of science points us toward an important set of issues insocial epistemology. If my reading of Science as a Process iscorrect, then most of Hull's critics (e.g., those who focus solelyon his account of conceptual selection) have ignored promisingaspects of his theory.

The goal of evolutionary theory is to (a) specify the general causal structure of evolving systems and (b) analyze evolutionary consequences that are expected to result from the proposed structure of the model systems. Biologists frequently emphasize the hypothetico-deductive method in evolutionary theory. I will show that this method primarily provides a tactical device for (b), while evolutionary synthesis requires a foundation of a unifying conceptual model for (a). Therefore, any successful strategy for a new synthesis requires both a new conceptual insight of evolving systems, and tactical devices for analyzing new specific aspects of the evolutionary process.

Philosophers of science have used various formulations of the "random mutation--natural selection" scheme to explain the development of scientific knowledge. But the uncritical acceptance of this evolutionary model has led to substantive problems concerning the relation between fact and theory. The primary difficulty lies in the fact that those who adopt this model (Popper and Kuhn, for example) are led to claim that theories arise chiefly through the processes of relatively random change. Systems theory constitutes a general criticism of this model insofar as it demonstrates the necessity of supplementing this mechanism with the non-random influences exercised by the internal organization of a system on its own development.

Philosophers have distinguished a metaphysical category which they term "historical entities" or "continuants". Such particulars are spatiotemporally localized and develop continuously through time while retaining internal cohesiveness. Species, social groups and conceptual systems can be profitably treated as historical entities. No damage is done to preanalytic intuitions in treating social groups as historical entities; both biological species and conceptual systems can be construed as historical entities only by modifying the ordinary way of viewing both. However, if species and conceptual systems are to "evolve", then they must be treated as historical entities. The type specimen method, which is used by systematists to individuate and name biological taxa, is set out and then extended to apply to scientific communities as social groups and conceptual systems.

A rejection of pure experience has prompted philosophers of science to adopt a certain perspective from which to view changes of belief. Popper, Kuhn, and others have analysed conceptual change in terms of problems or anomalies, that is, in terms of contingent reasoning about issues posed in the context of an inherited web of belief. This paper explores a more general analysis of conceptual change in dialogue with these philosophers of science. Because changes of belief are not all changes in scientific belief, we seek to unpack conceptual change in terms of dilemmas, as opposed to anomalies or problems. For a start, the notion of a dilemma has to be broader than that of an anomaly since it purports to apply to conceptual change as a whole, not just the transition from one era of normal science to another. In addition, we should detach the notion of a dilemma from the objectivism of Popper's world-3 problems.
