The new work on metaphor and gesture, as seen in the chapters in this volume, represents a major advance in the study of metaphor, and the psychology of human thought and communication. It comes as no surprise that people produce metaphoric gestures given their frequent use of metaphor in speech and writing. Nevertheless, the emerging literature on metaphor and gesture adds a significant source of evidence in support of the idea that abstract concepts are understood and communicated metaphorically. As several authors note in this volume, some cognitive scientists have raised skeptical questions about the possibility of metaphoric concepts because of the heavy reliance on linguistic evidence in making arguments for the existence of conceptual metaphor (e.g., Glucksberg, 2001; Murphy, 1996). These scholars argue that speaking about something metaphorically should not be seen as reliable data as to whether people actually think metaphorically, and urge that nonlinguistic evidence be gathered to support any claims about the metaphoric nature of ordinary thought. Indeed, the various kinds of research showing the prominence of metaphor in gesture in this volume not only provides nonlinguistic data skeptical scientists demand to support the possibility of metaphoric thought, but also shows how fundamental aspects of abstract thought are rooted in, and expressed by, recurring patterns of bodily experience and action.
