This article discusses the relation between emotions and testimony, by asking the questions: What do emotions do? Are emotions possible and desirable starting points for teaching difficult and complex subjects such as injustice and historical wounds? This article explores the 2015 image and testimony of Alan Kurdi, lying on a beach of the Mediterranean Sea and the immense emotional response it elicited from the media. By critiquing emotions based on testimonies in teaching, by primarily following Ahmed and Todd, this article (...) argues that emotions are cultural practices, not psychological states, and, thus, are relational. On this point, the argument is developed into two different movements, first, the effects offered by listening; second, opacity in relation to transparency, based on the thoughts of Glissant. The aspects of listening and opacity in relation to testimonies, in turn, yield an ambivalent space in which emotions play a role in students encounter with testimonies and may, in turn, imply educational possibilities.
