Barbara Postema opens this chapter by asserting that comics are a multimodal art form, combining image, text, sound, gesture, and spatial representation. She emphasizes the complexity of comics pages, which often include multiple textual registers and visual modes, requiring readers to integrate diverse elements to construct meaning. Johnathan Flowers responds by exploring formalist and non-formalist definitions of comics, arguing that comics should be understood as a medium rather than a fixed form. Drawing on thinkers like Scott McCloud, Thierry Groensteen, and John Dewey, Flowers highlights the expressive potential of comics and their cultural specificity. Postema’s reply underscores the significance of materiality and embodied experience in both the creation and interpretation of comics. The chapter concludes by affirming comics as a dynamic, multimodal medium, form, and art that engages readers through diverse formats and styles.
