[Lingtyp] Probabilistic typology vs. typology-based grammatical theory

Jan makes a number of interesting points, but I think the picture is 
somewhat more complex.

First, although his characterization of some of my work as probabilitic 
typology is not inaccurate, I not only share his taste expressed by “So 
for me the statistically insignificant variants in languages across the 
globe are at least as interesting and relevant as the statistically 
significant ones”, but, as I often communicate to others, the “rara” are 
to me far more interesting than the common features.

Second, “grammatical theory” means different things to different people. 
I think what Jan means is not only a theoretical framework in which to 
analyse languages, but a theoretical framework that makes empirical 
claims about what we find in language. To me and many typologists, 
grammatical theory primarily means explanations for why “languages are 
the way they are”. The theoretical framework for describing languages 
doesn’t matter a whole lot as long as it provides tools for adequately 
describing languages and does not impose things on the language for 
which there is no language-specific motivation. In that sense, it isn’t 
really theory at all. But I would also include as theoretical, 
typological work that characterizes that range of ways in which 
different languages do things.

Thus, from the perspective of my metatheoretical assumptions, Jan’s 
statement “A theory that can account for both common and unusual 
phenomena is superior to a theory that can only handle common 
grammatical phenomena” does not make sense, since theories for me do not 
“account for individual phenomena”. The rara are relevant to typological 
work in that they are crucial for demonstrating the range of ways that 
languages do things, and in so far as that is theory, they are of 
theoretical importance. But they are not particularly relevant to the 
theoretical goal of explaining why languages are the way they are, which 
I think is primarily explaining why the dominant patterns are dominant.

My point is not to argue that Jan is wrong, but simply that we need to 
be clear how ones views depend on one’s underlying metatheoretical 
assumptions.
