This article explores Wyndham Lewis's experience of the First World War, and its influence on his varied artistic output. It interrogates how Lewis's initial ambivalence towards an emergent technological society shifted through direct encounters with mechanized warfare, and speculates on the effect of these upon his post-war writing and criticism. By contrasting Lewis's thought against that of his Italian Futurist contemporaries, I will demonstrate the centrality of their divergent conceptions of masculinity in accounting for this opposition-and how Lewis's critique of technological society prefigures contemporary opposition towards the post-humanist philosophy of Accelerationism.
