Image. Orderly chaos in flight path of ocean-foraging albatross The case for scientific realism in the case of physics, microbiology, and chemistry is a strong one. The theories of physics, biology, and chemistry postulate unobservable entities, forces, and properties. These hypotheses are specified in a fair degree of precision. They are not individually testable, because …
Guest post by Doug Porpora on social structures
Here is a response to my earlier post on social ontology and structure from Doug Porpora, professor of sociology, Drexel University. Doug is the author of Reconstructing Sociology: The Critical Realist Approach. Thanks, Doug, for this thoughtful and considered reflection! FROM DOUG PORPORA: I have four comments in response. First, while I am happy to stand …

A flat social reality?
I've been inclined to talk about the social world in terms of levels or layers, with a few provisos -- multiple layers, causation across layers, fuzzy boundaries (link, link). But is this perhaps a misleading ontology? Would we be better served by thinking of the social world as "flat" -- involving processes and relations all …
Niiniluoto on scientific realism
Debates over realism have been at the center of the philosophy of science for at least seventy-five years. The fundamental question is this: what exists in the world? And how do we best gain knowledge about the nature and properties of these real things? The first question is metaphysical, while the second is epistemic. Scientific …
Critical realism and social heterogeneity
Is the metaphysics of critical realism compatible with the idea of a highly heterogeneous social world? Here is what I mean by heterogeneity in this context. First social causation is inherently multiple, with many kinds and tempos of social causation at work. It is therefore crucial that we avoid the impulse to reduce social change …

Social construction of technical knowledge
After there was the sociology of knowledge (link), before there was a new sociology of knowledge (link), and more or less simultaneous with science and technology studies (link), there was Paul Rabinow's excellent ethnography of the invention of the key tool in recombinant DNA research -- PCR (polymerase chain reaction). Rabinow's monograph Making PCR: A …

Microfoundations 2.0?
Figure. An orderly ontological hierarchy (University of Leeds (link) Figure. Complex non-reductionist social outcome -- blight The idea that hypotheses about social structures and forces require microfoundations has been around for at least 40 years. Maarten Janssen’s New Palgrave essay on microfoundations documents the history of the concept in economics; link. E. Roy Weintraub was …
Supervenience, isomers, and social isomers
A prior post focused on the question of whether chemistry supervenes upon physics, and I relied heavily on R. F. Hendry's treatment of the way that quantum chemistry attempts to explain the properties of various molecules based on fundamentals of quantum mechanics. This piece raised quite a bit of great discussion, from people who agree …

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 …
Microfoundations for rules and ascriptions
One of the more convincing arguments for the existence of social facts that lie above the level of individual actors is the social reality of rules and ascriptive identities. Bob and Alice are married by Reverend Green at 7 pm, July 1, 2015. The social fact that Bob and Alice are now married is not …
