Chasing Reality deals with the controversies over the reality of the external world. Distinguished philosopher Mario Bunge offers an extended defence of realism, a critique of various forms of contemporary anti-realism, and a sketch of his own version of realism, namely hylorealism. Bunge examines the main varieties of antirealism - Berkeley's, Hume's, and Kant's; positivism, phenomenology, and constructivism - and argues that all of these in fact hinder scientific research. Bunge's realist contention is that genuine explanations in the sciences appeal (...) to causal laws and mechanisms that are not directly observable, rather than simply to empirical generalisations. Genuine science, in his view, is objective even when it deals with subjective phenomena such as feelings of fear. This work defends a realist view of universals, kinds, possibilities, and dispositions, while rejecting contemporary accounts of these that are couched in terms of modal logic and 'possible worlds.'.

This article addresses the following problems: What is a mechanism, how can it be discovered, and what is the role of the knowledge of mechanisms in scientific explanation and technological control? The proposed answers are these. A mechanism is one of the processes in a concrete system that makes it what it is — for example, metabolism in cells, interneuronal connections in brains, work in factories and offices, research in laboratories, and litigation in courts of law. Because mechanisms are largely (...) or totally imperceptible, they must be conjectured. Once hypothesized they help explain, because a deep scientific explanation is an answer to a question of the form, "How does it work, that is, what makes it tick—what are its mechanisms?" Thus, by contrast with the subsumption of particulars under a generalization, an explanation proper consists in unveiling some lawful mechanism, as when political stability is explained by either coercion, public opinion manipulation, or democratic participation. Finding mechanisms satisfies not only the yearning for understanding, but also the need for control. Key Words: explanation • function • mechanism • process • system • systemism. (shrink)

Most philosophical accounts of emergence are incompatible with reduction. Most scientists regard a system property as emergent relative to properties of its parts if it depends upon their mode of organization-a view consistent with reduction. Emergence is a failure of aggregativity, in which ``the whole is nothing more than the sum of its parts''. Aggregativity requires four conditions, giving powerful tools for analyzing modes of organization. Differently met for different decompositions of the system, and in different degrees, the structural conditions (...) can provide evaluation criteria for choosing decompositions, ``natural kinds'', and detecting functional localization fallacies, approximations, and various biases of vulgar reductionisms. This analysis of emergence and use of these conditions as heuristics is consistent with a broader reductionistic methodology. (shrink)

Margaret Archer and Pierre Bourdieu have advanced what seem at first sight to be incompatible theories of human agency. While Archer places heavy stress on conscious reflexive deliberation and the consequent choices of identity and projects that individuals make, Bourdieu's concept of habitus places equally heavy stress on the role of social conditioning in determining our behavior, and downplays the contribution of conscious deliberation. Despite this, I argue that these two approaches, with some modification, can be reconciled in a single (...) emergentist theory of human action that is sketched out in this article. It examines how human dispositions and our reflexive decisions are related to the determination of human action, linking dispositions and decisions to their neural base in human physiology and to the social factors that influence them. As a result, it argues, we can see human action as the outcome of a continuous interaction between dispositions and reflexivity. The article goes on to relate this explanation back to Bourdieu's concept of the habitus and Archer's account of reflexivity. It argues that the weaknesses in Bourdieu's theory of action can be resolved by a reasonable reinterpretation of the habitus that makes it consistent with the emergentist theory and creates space for human choices as well as social influences on our behavior. This opens up a role for the sort of reflexive deliberations advocated by Archer and thus to a reconciliation of the key contributions of both Archer and Bourdieu. (shrink)

The question of social structure and its relationship to human agency remains one of the central problems of social theory. One of the most promising attempts to provide a solution has been Margaret Archer's morphogenetic approach, which invokes emergence to justify treating social structure as causally effective. Archer's argument, however, has been criticised by a number of authors who suggest that the examples she cites can be explained in reductionist terms and thus that they fail to sustain her claim for (...) the independent causal effectiveness of social structure. This paper offers an alternative argument to support the emergentist claim for the causal effectiveness of social structure, and shows how this argument refutes a representative critique of social emergence.

This paper aims to improve critical realism's understanding of emergence by discussing, first, what emergence is and how it works; second, the need for a compositional account of emergence; and third, the implications of emergence for causation. It goes on to argue that the theory of emergence leads to the recognition of certain hitherto neglected similarities between real causal powers and actual causation. (edited).

This article analyses and evaluates the uses of the concept of causal power in the critical realist tradition, which is based on Roy Bhaskar's philosophy of science. The concept of causal power that appears in the early works of Rom Harré and his associates is compared to Bhaskar's account of this concept and its uses in the critical realist social ontology. It is argued that the concept of emergence should be incorporated to any adequate notion of causal power. The concept (...) of emergence used in Bhaskar and other critical realists’ works is shown to be ambiguous. It is also pointed out that the concept of causal power should be analysed in an anti-essentialist way. Ontological and methodological problems that vitiate Bhaskar's transcendental account of the concept of causal power are examined. Moreover, it is argued that the applications of the concept of causal power to mental powers, reasons, and social structures in the critical realist social ontology are problematic. The paper shows how these problems might be avoided without giving up the concept of causal power and the notion of structural social causation. (shrink)

This article discusses the theories of social emergence developed by Roy Bhaskar and Mario Bunge. Bhaskar's concept of emergent causal power is shown to be ambiguous, and some of the difficulties of his depth-relational concept of social emergence are examined. It is argued that Bunge's systemic concept of emergent property is not only different, but also clearer and more consistent than Bhaskar's concept of emergent causal power. Despite its clarity and consistency, Bunge's definition of the concept of emergent property is (...) shown to be too broad and analytically imprecise for the purposes of an emergentist social ontology. It is argued that Bunge's systemic account of social emergence can be developed further by using William Wimsatt's gradual approach to emergent phenomena and his four conditions of aggregativity of a systemic property. It is shown that these conditions provide useful conceptual tools for clarifying and investigating different kinds of mechanisms of social emergence and developing stronger varieties of the concept of emergent social property than that indicated in Bunge's definition of this concept.

This paper clarifies the terms “institutions” and “social structures” and related terms “rules”, “conventions”, “norms”, “values” and “customs”. Part one explores the similarities between institutions and social structures whilst the second and third parts explore differences. Part two considers institutions, rules, habits or habitus and habituation, whilst part three critically reflects on three common conceptions of social structures. The conclusion comments upon reflexive deliberation via the internal conversation.

Social systems theory has been dominated in recent years by the work of Niklas Luhmann, but there is another strand of systems thinking, which is receiving increasing attention in sociology: emergentism. For emergentism, the core problems of systems thinking are concerned with causation and reductionism; for Luhmann, they are questions of meaning and self-reference. Arguing from an emergentist perspective, the article finds that emergentism addresses its own core problem successfully, while Luhmann's approach is incapable of resolving questions of causation and (...) reductionism. On the other hand, neither paradigm yet has a convincing response to the challenges of meaning and self-reference. Key Words: social systems • emergence • paradigms • autopoiesis • critical realism.

The article discusses principles that form part of evolutionary systems thinking in social sciences and humanities. It is argued that introducing the concept of self-organization relates agency and structures in a way that makes it possible to take up certain features of Critical Theory by which it can meet the demands for a critical social science. These principles are applied to the question of whether there is convergence or divergence in and by means of the Internet. It will be clarified (...) that the Internet is basically a social system and that it is a subsystem of the larger and overarching system of the whole society. It will be shown how the Internet can be perceived as a possible trigger for societal developments bringing about fundamental change in the nature of society. Thus the article cuts across philosophical, system theoretical, social theoretical, sociology of technology, and information society theory considerations. Key Words: dynamic • "mechanism" • self-organizaton • revolution • evolution • Critical Theory • information society • Internet. (shrink)

Richard Levins’ distinction between aggregate, composed and evolved systems acquires new significance as we recognize the importance of mechanistic explanation. Criteria for aggregativity provide limiting cases for absence of organization, so through their failure, can provide rich detectors for organizational properties. I explore the use of failures of aggregativity for the analysis of mechanistic systems in diverse contexts. Aggregativity appears theoretically desireable, but we are easily fooled. It may be exaggerated through approximation, conditions of derivation, and extrapolating from some conditions (...) of decomposition illegtimately to others. Evolved systems particularly may require analyses under alternative complementary decompositions. Exploring these conditions helps us to better understand the strengths and limits of reductionistic methods. (shrink)
