As the good Tom Waits would say, I want to pull on your coat about something. As I've been revamping my cv and hunting for advisors for the next round of phd applications, I've begun once again lamenting the fragmentation of my field. I suppose I should tell you what my field is but, y'see, that's where all the problems lie: there's no such field. As diverse and Renaissance as my interests are, they're all three sides of the same coin: language, sociality, and intelligence.
So, first things first. Evidently language is a diverse topic, but I mean to focus on formal and theoretical matters, the quintessence of what makes what we call "language". The early work of Chomsky to the contrary, there's an unfortunate —though entirely understandable— break between the study of formal languages and natural languages. On the natural side I'm interested in morphology and its interfaces with other components of language (morphophonology, morphosyntax & scrambling, morphosemantics & nuance). On the formal side I'm interested in the design of programming languages, ontologies, and interfaces. And on the middle side I'm interested in grammar formalisms like TAG and CCG as well as the automata theory that drives these and parsers and machine translation.
Sociality is also a diverse topic, without even accounting for the fact that I'm abusing the term to cover both the structure of societies and the interactions within and between them. Here too there's an unfortunate —though entirely understandable— break between the humanities and the sciences. In the humanities I'm interested in anthropology, gender/sexuality studies, performativity, the body as media, urban neo-tribalism, and online communities. More scientifically I'm interested in nonlinear systems theory, information theory, chaos theory, catastrophe theory, scale-free networks, and theoretical genetics. And again, on the middle side there are issues of sociolinguistics: code switching, emotional particles, uses of prosody, politeness and group-formation; and evolution: both evolutionary computation, and also cultural and linguistic evolution.
And as you may no doubt be gathering, studies of intelligence too are vast and harshly divided— between wetware and hardware, or between cognition and computation if you prefer. Language is often pegged as a fundamental component to humanity's ability for higher thought, and yet even despite this the majority of linguistic formalisms neglect questions of how cognitively realistic they are as models of actual human linguistic performance. Over on the side of artificial intelligence and artificial life there's a rift between those studying complexity, adaptation, and emergence vs those trying to hammer thought and knowledge into the rigid formalisms of logic and probability. Sandwiched between these conflicts are the war-torn battle grounds of machine translation, language learning, and language acquisition.
So how many fields are involved in this tripartite Janus of interfaces, systems, and agency? To make a short list: linguistics, mathematics, computer science, cultural anthropology, gender/queer/feminist studies, women's lit, systems science/systems theory, cognitive science, social psychology, computational biology, artificial intelligence/artificial life/machine learning, and given the vagaries of universities often electrical engineering and philosophy for good measure. How many is that? Too goddamned many, that's how many. And to top it off, all of them are interdisciplinary to boot. Now you may be saying to yourself that I'm trying too hard to unify too many disparate discourses, and perhaps it's true, but there is a cohesion there which should be evident by the extent to which each of those many fields crosscut these three seemingly simple categories.( Systems theory gets it right when they say that the current state of science is burdened by its focus on fundamentalism. )
