I've been seriously interested in the question of character since being invited to contribute to a volume on the subject a few years ago. That volume, Questions of Character, has now appeared in print, and it is an excellent and engaging contribution. Iskra Fileva was the director of the project and is the editor of …
Coarse-graining of complex systems
The question of the relationship between micro-level and macro-level is just as important in physics as it is in sociology. Is it possible to derive the macro-states of a system from information about the micro-states of the system? It turns out that there are some surprising aspects of the relationship between micro and macro that …

I've been a member since 1998, approaching half the lifetime of the association, and I continue to find it the most satisfying and stimulating of my professional associations.

DeLanda on concepts, knobs, and phase transitions

This diagram is valuable because it provides a finely granulated classification of kinds of social action, differentiated by the relationships that each kind stipulates among individuals within the interaction. Here is …

New structural economics
Does economic theory provide anything like a concrete set of reliable policies for creating sustained economic growth in a middle-income country? Some contemporary economists believe that it is possible to answer this question in the affirmative. However, I don't find this confidence justified. One such economist is Justin Yifu Lin. Lin is a leading Chinese …
Rational choice institutionalism

These are questions that historical institutionalists like Kathleen Thelen have considered in substantial depth (link, link, link). But the rational-choice paradigm has also offered some answers to these questions as well. The basic …
A new exposition of assemblage theory
Manuel DeLanda has been a prominent exponent of the theory of assemblage for English-speaking readers for at least ten years. His 2006 book A New Philosophy of Society: Assemblage Theory and Social Complexity has been discussed numerous times in this blog (link, link, link). DeLanda has now published a new treatment of the subject, Assemblage …
What is “conceptual history”?
The post-war German historian Reinhart Koselleck made important contributions to the theory of history that are largely independent from the other sources of Continental philosophy of history mentioned elsewhere in this blog. (Koselleck’s contributions are ably discussed in Niklas Olsen's History in the Plural: An Introduction to the Work of Reinhart Koselleck (2012).) Koselleck contributed to …
