Political speeches are a prime example of how discourse often requires speakers to convey multiple competing viewpoints, both their own and others’. Cognitive linguists have shown how, in speech, speakers express viewpoint through individual choices at the lexical and grammatical level. Recently, cognitive linguists have also shown that speakers express viewpoint using speech-accompanying gestures. To date, the study of viewpoint expression has focused on cases where speakers deliver the same viewpoint across modalities. By examining the persuasive uses of gesture in Obama’s A More Perfect Union speech, I show how speakers can communicate multiple different viewpoints across gesture and speech, simultaneously. There are moments when Obama expresses his opponents’ viewpoint in speech, while framing them in terms of his own viewpoint in gesture, and vice versa. I discuss how the deviation of viewpoints across modalities provides key insights into multimodal cognition, with respect to working memory, metaphor, and persuasion. Specifically, I argue that, as an implicit medium, gesture allows speakers to inject viewpoint into the uptake of speech, below the conscious radar of recipients, and I discuss how this rhetorical capacity is evolving as a result of communication technologies.
