In the recent methodological individualism-holism debate on explanation, there has been considerable focus on what reasons methodological holists may advance in support of their position. We believe it is useful to approach the other direction and ask what considerations methodological individualists may in fact offer in favor of their view about explanation. This is the background for the question we pursue in this paper: Why be a methodological individualist? We start out by introducing the methodological individualism-holism debate while distinguishing two (...) forms of methodological individualism: a form that says that individualist explanations are always better than holist accounts and a form that says that providing intervening individualist mechanisms always makes for better explanations than purely holist ones. Next, we consider four lines of reasoning in support of methodological individualism: arguments from causation, from explanatory depth, from agency, and from normativity. We argue that none of them offer convincing reasons in support of the two explanatory versions of individualism we consider. While there may well be occasions in which individualists’ favorite explanations are superior, we find no reason to think this always must be the case. (shrink)

This article first surveys a significant set of issues that are intertwined in asking whether social classes are real. It distinguishes two different notions of class: class as organized social entities and class as types of individuals based on individual characteristics. There is good evidence for some classes as social entities—ruling classes and underclasses in some societies—but other classes in contemporary society are sometimes best thought of in terms of types, not social entities. Implications are drawn for pluralist accounts of (...) social classification and the individualism-holism dispute. (shrink)

In a number of very influential publications, Epstein and Hoover (among other authors) have recently argued that a thoroughly micro-foundationalist approach towards economics is unconvincing for metaphysical reasons. However, as we show in this article, this metaphysical/social ontological approach to the debate fails to resolve the status of micro-foundations in the practice of economic modelling. To overcome this, we argue that endogenizing a model—that is, providing micro-foundations for it—correlates with making that model more complex. Specifically, we show that models with (...) more micro-foundations tend to have more parameters or variables. This matters, as there are well-established methodological reasons for preferring models with fewer parameters or variables—ceteris paribus. We therefore conclude that, from a practice-based point of view, micro-foundations are only defensible to the extent that they significantly improve the ability of the relevant model to fit the data of interest. In this way, we arrive at a practice-based, methodological reconceptualization of the debate surrounding the need for micro-foundations in economics. (shrink)

Agent-based models are increasingly important in social science research. They have two obvious apparent virtues: they can model complex macrosociological phenomena without strong assumptions about agents and without analytic solutions for models, and they seem to instantiate the methodological individualist program in a concrete way. We argue that the latter claim is false. After providing schematic accounts of ABM models and a first introduction to ways in which to characterize individualist explanations, we work through six conceptions of individualist explanations that (...) are decreasingly "less individualist" and argue that ABM-based explanations in the social sciences are not inevitably individualist in any of these senses. ABMs allow for explanatory relations among social entities and properties in the model environment and they are silent on what basic agents are, allowing social entities and properties to play basic explanatory roles.

The idea that mechanisms are crucially important to differentiate between genuine and spurious causal relations is ubiquitous both in the philosophical and in the social scientific literature. Yet...

The predictive inadequacy of the social sciences is well documented, and philosophers have sought to diagnose it. This paper examines Brian Epstein’s recent diagnosis. He argues that the social sciences treat the social world as entirely composed of individual people. Instead, social scientists should recognize that material, non-individualistic entities determine the social world, as well. First, I argue that Epstein’s argument both begs the question against his opponents and is not sufficiently charitable. Second, I present doubts that his proposal will (...) improve predictive success for the social sciences, which I support with Edith Penrose’s resource-based theory of the firm. (shrink)
