Abstract
Proponents of the “literacy” thesis share with proponents of the “extended mind” thesis the viewpoint that communication systems such as language or writing have cognitive implications that go beyond their purely social and communicative purposes. Conceiving of media as extensions of the mind thus has the potential to bring together and cross-fertilize research programs that are currently placed in distant corners of the study of mind, language, and society. In this issue, we bring together authors with a diverse set of interests to identify promising areas of overlap, blaze new trails for us to explore, but also to highlight dissonances and challenges that will have to be addressed in future work
