Universals and diversity in gesture: Research past, present, and future

At the dawn of anthropology, gesture was widely considered a “universal language.” In the 20th century, however, this framing fell out of favor as anthropologists rejected universalism in favor of relativism. These polemical positions were largely fueled by high-flying rhetoric and second-hand report; researchers had neither the data nor the conceptual frameworks to stake out substantive positions. Today we have much more data, but our frameworks remain underdeveloped and often implicit. Here, I outline several emerging conceptual tools that help us make sense of universals and diversity in gesture. I then sketch the state of our knowledge about a handful of gestural phenomena, further developing these conceptual tools on the way. This brief survey underscores a clear conclusion: gesture is unmistakably similar around the world while also being broadly diverse. Our task ahead is to put polemics aside and explore this duality systematically—and soon, before gestural diversity dwindles further.
