According to one large family of views, scientific explanations explain a phenomenon (such as an event or a regularity) by subsuming it under a general representation, model, prototype, or schema (see Bechtel, W., & Abrahamsen, A. (2005). Explanation: A mechanist alternative. Studies in History and Philosophy of Biological and Biomedical Sciences, 36(2), 421–441; Churchland, P. M. (1989). A neurocomputational perspective: The nature of mind and the structure of science. Cambridge: MIT Press; Darden (2006); Hempel, C. G. (1965). Aspects of scientific (...) explanation. In C. G. Hempel (Ed.), Aspects of scientific explanation (pp. 331–496). New York: Free Press; Kitcher (1989); Machamer, P., Darden, L., & Craver, C. F. (2000). Thinking about mechanisms. Philosophy of Science, 67(1), 1–25). My concern is with the minimal suggestion that an adequate philosophical theory of scientific explanation can limit its attention to the format or structure with which theories are represented. The representational subsumption view is a plausible hypothesis about the psychology of understanding. It is also a plausible claim about how scientists present their knowledge to the world. However, one cannot address the central questions for a philosophical theory of scientific explanation without turning one’s attention from the structure of representations to the basic commitments about the worldly structures that plausibly count as explanatory. A philosophical theory of scientific explanation should achieve two goals. The first is explanatory demarcation. It should show how explanation relates with other scientific achievements, such as control, description, measurement, prediction, and taxonomy. The second is explanatory normativity. It should say when putative explanations succeed and fail. One cannot achieve these goals without undertaking commitments about the kinds of ontic structures that plausibly count as explanatory. Representations convey explanatory information about a phenomenon when and only when they describe the ontic explanations for those phenomena. (shrink)

The concept of mechanism in biology has three distinct meanings. It may refer to a philosophical thesis about the nature of life and biology (‘mechanicism’), to the internal workings of a machine-like structure (‘machine mechanism’), or to the causal explanation of a particular phenomenon (‘causal mechanism’). In this paper I trace the conceptual evolution of ‘mechanism’ in the history of biology, and I examine how the three meanings of this term have come to be featured in the philosophy of biology, (...) situating the new ‘mechanismic program’ in this context. I argue that the leading advocates of the mechanismic program (i.e., Craver, Darden, Bechtel, etc.) inadvertently conflate the different senses of ‘mechanism’. Specifically, they all inappropriately endow causal mechanisms with the ontic status of machine mechanisms, and this invariably results in problematic accounts of the role played by mechanism-talk in scientific practice. I suggest that for effective analyses of the concept of mechanism, causal mechanisms need to be distinguished from machine mechanisms, and the new mechanismic program in the philosophy of biology needs to be demarcated from the traditional concerns of mechanistic biology.

Nursing scholars continuously refine nursing knowledge and the philosophical foundations of nursing practice. They advance nursing knowledge by creating new knowledge and weighing the relevance of developments in cognate sciences. Nurse philosophers go further by providing epistemological and ontological arguments for explanations of nursing phenomena. In this article, I engage with Bender's arguments about why mechanisms should have more primacy as carriers of nursing knowledge. Despite the careful scholarship involved, Bender's arguments need to be more convincing. Accordingly, this article encourages (...) debate about Bender's arguments for reorientating nursing science to mechanisms. I begin by suggesting that the claim that the theory‐practice divide can be overcome by reorientating to mechanisms is acceptable only if we accept Bender's depiction of the challenge. Then I question the ontology Bender relies on to justify reorientating nursing science. After that, I argue that mechanisms in models that parallel analytical sociology undermine the kind of nursing science Bender advocates. I illustrate my arguments with a social mechanism thought experiment. Then I explain why Bender's arguments cannot escape the received view of science or inform emancipatory nursing action without theory. Finally, I mention some caveats and implications for nursing science. (shrink)

This article challenges the view that sociological explanation is based on methodological individualism and suggests using relational concepts for constructing explanations of social phenomena. It develops a relational concept of social mechanisms based on sociological systems theory and illustrates its explanatory power by drawing on research on changes in educational organizations in Germany.

Generalization from a case study is a perennial issue in the methodology of the social sciences. The case study is one of the most important research designs in many social scientific fields, but no shared understanding exists of the epistemic import of case studies. This article suggests that the idea of mechanism-based theorizing provides a fruitful basis for understanding how case studies contribute to a general understanding of social phenomena. This approach is illustrated with a re- construction of Espeland and (...) Sauder's case study of the effects of rankings on US legal education. On the basis of the reconstruction, it is argued that, at least with respect to sociology, the idea of mechanism-based theorizing captures many of the generalizable elements of case studies.

La influencia de los mensajes periodísticos en la formación de las actitudes morales se considera más que probable, pero su estudio empírico conseguirá unas conclusiones válidas sólo si se apoya en una sólida base filosófica. Ella es imprescindible para elaborar una definición de lo moral que permita desarrollar hipótesis y variables para la investigación de campo. El marco más adecuado parece ofrecer el emotivismo de Ch. L. Stevenson combinado con la teoría de la intencionalidad de J. Searle, porque establece un (...) puente conceptual entre el análisis teórico del fenómeno moral y las regularidades de la formación de las actitudes, recogidas en las teorías de rango medio de la Cognición Social y de la Psicología Moral. Sólo con una síntesis teórica que abarque el proceso en su totalidad puede plantearse la pregunta sobre la influencia de las noticias periodísticas en él. (shrink)

The mechanism-realist paradigm in the philosophy of science, championed by Mario Bunge and Roy Bhaskar, sets certain expectations for the substantive social-scientific application of the paradigm. To evaluate the application of the paradigm in accomplished substantive research, as well as the potential for future research, I examine the work of Charles Tilly, the exemplary substantive work in the mechanism-realist tradition. Based on this examination, I argue for the usefulness of explanatory mechanisms, provided that they are couched in terms of a (...) heuristic. Such a position is the most reasonable one to adopt given the expectations set by the paradigm in relation to complexity stemming from mechanism interaction and to a notion of causality that is deeper than that acknowledged by empiricism and positivism.

Does systems theory need rethinking? Most social scientists would probably say no. It had its run, was debated critically, and found wanting. If at all, it should be treated historically. Why then might systems theory need rethinking, as the title of this symposium claims? The reason is that, unlike in the natural and biosocial sciences, any conception of system in the social sciences has remained suspect in the wake of problematic Parsonian and cybernetic systems theories. The premise of this special (...) issue is that abandoning conceptions of systems has imposed a high price on the social sciences: a lack of ontologies and methodologies that are both philosophically profound and scientifically defensible. It has left social scientists who choose to ignore ontology in their theoretical and empirical work defenseless against enterprising settlers from a variety of humanities and social science disciplines who attack mainstream work with—often simplistic and naïve, but nevertheless fundamental—philosophical arguments, whether anti-scientific postmodernists or pseudo-scientific rational choice theorists. The goal of this special issue is to showcase new and original work that contributes to a rethinking of systems theory by taking the conception of systems seriously. This introduction offers a programmatic statement of a systemic ontology and methodology as well as a brief general outline and examples of what a systems-based approach in the social sciences entails. Key Words: systems theory • systemism • systemic approach • complexity theory • self-organization • emergentism • paradigms • social mechanisms • Mario Bunge. (shrink)

According to an influential epistemological tradition, science explains phenomena on the basis of laws, but the last two decades have witnessed a neo-mechanistic movement that emphasizes the fundamental role of mechanism-based explanations in science, which have the virtue of opening the “black box” of correlations and of providing a genuine understanding of the phenomena. Mechanisms enrich the empirical content of a theory by introducing a new set of variables, helping us to make causal inferences that are not possible on the (...) basis of macro-level correlations. However, the appeal to mechanisms has also a methodological price. They are vulnerable to interference effects; they also face underdetermination problems, because the available evidence often allows different interpretations of the underlying structure of a correlation; they are strongly context-dependent and their individuation as causal patterns can be controversial; they present specific testability problems; finally, mechanism-based extrapolations can be misleading due to the local character of mechanisms. At any rate, the study of mechanisms is an indispensable part of the human sciences, and the problems that they raise can be controlled by quantitative and qualitative methods, and an epistemologically informed exercise of critical thinking.

As a promising Social Science Methodology, Structural/Mechanism Explanation (SME) retains the advantages of mechanism-based explanation (ME), particularly its focus on “identifying causal patterns from micro-level social phenomena.” It also acknowledging the role of “structure”—seen as “macro-level conditions”—in incentivizing or disincentivizing key mechanisms, thus proving valuable for forecasting their emergence and decline. This article explores the theory of SME and applies it to examine how a revitalized “Legalist political structure coupled with a Confucianist ideological structure” can forecast the mechanisms by which (...) China’s National Social Credit System disciplines and punishes the citizens. This is observed across domains of legislation, administration, judiciary, and propaganda. (shrink)

In this article, we discuss the issue of context-dependence of mechanism-based explanation in the social sciences. The different ways in which the context-dependence and context-independence of mechanism-based explanation have been understood in the social sciences are often motivated by different and apparently incompatible understandings of what explanatory mechanisms are. Instead, we suggest that the different varieties of context-dependence are best seen as corresponding to different research goals. Rather than conflicting with one another, these goals are complementary to each other and (...) therefore pave the way to a methodologically more cooperative approach to mechanism-based explanation in the social sciences.
