The Duck of Minerva has taken up my "constructivism won" thesis, and has sparked one of the most interesting blog debates on constructivism ever. Okay, maybe the only blog debate of constructivism ever, but it's really interesting. [warning: another long IR theory post follows. Read at your own risk.]
Dan Nexon kicked off with some very provocative and interesting questions about the relationship between realism, liberalism (IR version), and constructivism:
First, is "neoconservativism" a conservative variant of constructivism? It would seem to follow (and I think this summarizes Marc's position well) that academic constructivism is liberal. Although the two positions are not exclusive, Marc's reading provides a different perspective than the standard view of neoconservativism as "Wilsonsian with teeth," i.e., a "neo-Reganite" synthesis of Wilsonsian idealism with a more hard-headed recognition of the importance of, and transformative potential of, military force.
...
Contemporary mainline constructivism (as opposed to, say "critical" constructivisms) does seem to be a variant of liberal theory. One could argue that "constructivism," in its present form, takes up the "sociological" dimensions of liberal idealism, while "liberalism" represents the rationalist and economistic trajectory of the liberal-idealist worldview.
I would disagree with the idea that academic constructivism is politically liberal. As I argued ad nauseum at our recent constructivism workshop, it is very important that constructivism not be construed as a "liberals club" where everyone agrees on the basic normative and political preferences. After all, the whole point of constructivism is that such preferences, identities, and normative positions are constructed through political, rhetorical, or [fill in the blank] means. Granted, in practice constructivists often take up issues such as global civil society, norms against various bad things, human rights, and so forth - but that there is absolutely nothing inherent to constructivist theory that requires it to be politically liberal.
Constructivism should have a lot to say about how to create a norm against terrorism, or about how civilizational identities create conflict, how to legitimize American hegemony, or other politically conservative issues. It should equally have a lot to say about how religion matters in politics, whether that is Christianity or Islam (although to date it regrettably hasn't). Constructivism as a paradigm should be neutral as to the content of the norms, identities and values being contested, constructed, defended, internalized, and so forth. Hence, Osama bin Laden should be seen as a constructivist in practice: in his political practice, ideas have power independent of material resources, and the goal is the construction of an overarching Muslim identity transcending state boundaries. It shouldn't matter for a constructivist analysis of al-Qaeda that his goals are the antithesis of liberalism.
Then Rodger Payne jumped in, denying that his form of critical theory could be called liberal, or post-structuralist. He defends a Habermas-based "critical constructivism." Which sends commenters into a flurry, because IR syllabi now conventionally divide constructivism into maintream constructivism (of the sort that I do, analyzing causal arguments about the relationships among identities, interests, discourse, norms, and so forth) and "critical" constructivism (which encompasses much of the post-structuralist strand of IR theory).
Patrick Jackson then responded with a denunciation of Habermas, defending a different version of critical constructivism. He argued for his version of "rhetorical coercion", which would render Habermasian communicative action impossible (sorry about that sentence, folks, but that's what happens when IR folks talk among themselves). I think Patrick's argument is too strong here: rhetorical coercion happens some times, but communicative action happens at other times. Why insist that only one logic is always operative? Isn't that an empirical question? My Iraq sanctions paper deals with exactly this point - the impact of deceptive or coercive rhetorical action on the possibility for real communicative exchange (short answer: useful in the short term tactically, devastating in the longer term).
Meanwhile, the commenting chorus bemoans the implacable advance of constructivism in the field, describing it as a Borg, incorporating everything it encounters, against which resistance is futile.
I admit to being a bit fatigued by attempts to define constructivism, to set boundaries on what counts as what kind of constructivism or what gets to be called "critical." I don't much care - I'm more interested in trying to answer interesting questions, using whatever methods are available, than I am in defending any particular paradigm. What they (and all constructivists, and IR theorists) need to do is to make these theoretical approaches relevant, to show how they can be applied to real world issues and provide better answers to tough empirical, normative, or political questions. It sounds like the Duck authors are doing that, so more power to them. Either way, I'm delighted to see them take up my provocation and run with it - there should be more of this kind of discussion about IR theory on blogs.
Quack.
