Computational sociology models social phenomena using the concepts of emergence and downward causation. However, the theoretical status of these concepts is ambiguous; they suppose too much ontology and are invoked by two opposed sociological interpretations of social reality: the individualistic and the holistic. This paper aims to clarify those concepts and argue in favour of their heuristic value for social simulation. It does so by proposing a link between the concept of emergence and Luhmann's theory of communication. For Luhmann, society (...) emerges from the bottom-up as communication and he describes the process by which society limits the possible selections of individuals as downward causation. It is argued that this theory is well positioned to overcome some epistemological drawbacks in computational sociology. (shrink)

I give an account of Max Weber's views concerning the basis of the objectivity of the cultural sciences. In this connection, I offer a critical discussion of his distinction between different "value spheres," each with its own "intrinsic logic." I then consider parallels between Weber's "value spheres" and central elements of Bourdieu's field theory and Luhmann's systems theory, and try to show to what extent Bourdieu's and Luhmann's problems, and the solutions they suggest, can be seen as similar to Weber's. (...) I conclude by a general consideration of Weber's, Bourdieu's, and Luhmann's approach to the problem of objectivity. Key Words: Max Weber • Pierre Bourdieu • Niklas Luhmann • social differentiation • objectivity • value spheres • inherent logic • field theory • systems theory. (shrink)

The public debate on climate change is filled with moral claims. However, scientific knowledge about the role that morality, ethics, and values play in this issue is still scarce. Starting from this research gap, we focus on corporations as central decision makers in modern society and analyze how they respond to societal demands to take responsibility for climate change. While relevant literature on business ethics and climate change either places a high premium on morality or presents a strong skeptical bias, (...) our sociological model depicts morality as an indeterminate force: it can lead to both workable solutions or merely reinforce the status quo, depending on what different corporations make of it. We describe, on the one side, the diffusion of moral values in the media discourse on climate change and, on the other side, the specific responses of corporations. While the media discourse generates a pressure on corporations to act responsibly, their moral claims do not provide clear advice for action. As a result, morality becomes available to organizations as a medium that can be re-specified according to their internal dynamics. Corporations transform moral values into something compatible with their own structures through a variety of different responses: introducing formal ethical structures (e.g., codes of conduct), initiating value-oriented projects, or developing informal moral norms, and so on. In some occurrences, morality becomes a mere façade, while in others it serves as a decision-making criterion and deeply influences core activities in firms. (shrink)
