Responding to Guattari’s call for a ‘mutation of mentality’, the article explores unconventional horse-assisted leadership learning as promising ways of embodied learning to be affected and response-able. By drawing on and continuing the work of Guattari and posthuman feminist scholars, we aim to show that studying the affective pedagogics of opening up the senses and learning to be affected is of vital importance. We analyse a posthuman auto-ethnography of developing capabilities to live and breathe together that allow us to relate (...) in alternative ways. Experiments with affective pedagogy are conducted as they affect bodies through indeterminate and liminal contact zones and use aesthetics to evoke transformation in senses and thoughts, care and response. Since they are both domesticated and non-human, horses are promising companions in this endeavour of entrainment. However, these sensorial experiments also call for an ethics of cutting connections and, not least, of permitting refusals of refusals. (shrink)
