Brian Epstein’s radical metaphysics

Brian Epstein is adamant that the social sciences need to think very differently about the nature of the social world. In The Ant Trap: Rebuilding the Foundations of the Social Sciences he sets out to blow up our conventional thinking about the relation between individuals and social facts. In particular, he is fundamentally skeptical about any conception …

Mechanisms according to analytical sociology

One of the distinguishing characteristics of analytical sociology is its insistence on the idea of causal mechanisms as the core component of explanation. Like post-positivists in other traditions, AS theorists specifically reject the covering law model of explanation and argues for a "realist" understanding of causal relations and powers: a causal relationship between x and y exists solely insofar …

Reduction and generativeness

Providing an ontology of complex entities seems to force us to refer to some notion of higher-level and lower-level things. Proteins consist of atoms; atoms consist of protons, electrons, and neutrons; and cells are agglomerations of many things, including proteins. This describes a relation of composition between a set of lower-level things and the higher-level …

Is chemistry supervenient on physics?

Many philosophers of science and physicists take it for granted that "physics" determines "chemistry". Or in terms of the theory of supervenience, it is commonly supposed that the domain of chemistry supervenes upon the domain of fundamental physics. This is the thesis of physicalism: the idea that all causation ultimately depends on the causal powers …

Quantum mental processes?

One of the pleasant aspects of a long career in philosophy is the occasional experience of a genuinely novel approach to familiar problems. Sometimes one's reaction is skeptical at first -- "that's a crazy idea!". And sometimes the approach turns out to have genuine promise. I've had that experience of moving from profound doubt to …

Kaidesoja on emergence

Tuukka Kaidesoja's recent book Naturalizing Critical Realist Social Ontology devotes a chapter to the topic of emergence as it is treated within critical realism. Roy Bhaskar insisted that the assumption of emergence was crucial to the theory of critical realism. Kaidesoja sorts out what Bhaskar means by emergence, which turns out to be ambiguous and inconsistent, and offers his …

Issues about microfoundations

I believe that hypotheses, theories, and explanations in the social sciences need to be subject to the requirement of microfoundationalism. This requirement can be understood in a weak and a strong version, and sometimes people understand the idea as a requirement of reductionism.  In brief, I defend the position in a weak form that does …

Response to Little by Tuukka Kaidesoja

[Tuukka Kaidesoja accepted my invitation to write a response to my discussion (link) of his recent article in Philosophy of the Social Sciences, “Overcoming the Biases of Microfoundations: Social Mechanisms and Collective Agents”. Currently Kaidesoja works as a post-doctoral researcher at the Finnish Academy Centre of Excellence in the Philosophy of the Social Sciences, Department of …

Social mechanisms and meso-level causes

(This post summarizes a paper I presented at the British Society for the Philosophy of Science Annual Meeting in 2012.) Here and elsewhere I want to defend the theoretical possibility of attributing causal powers to meso-level social entities and structures. In this I follow a number of philosophers and sociologists, including many critical realists (e.g. …

Does the microfoundations principle imply reductionism?

My philosophy of social science has always and consistently maintained the idea that social facts depend on the activities and beliefs of individuals. There is no social "stuff" that exists independently from individual actors. I have encapsulated that idea in the form of the "microfoundations" principle: any claim about the characteristics or causal powers of …
