One of the defining features of the developing field of the Digital Humanities (DH) is its interdisciplinary character. This paper will attempt to indicate how theological insights can contribute at a more theoretical level to DH. Specifically, it will attempt to suggest a way that Marshall McLuhan can contribute positively to defining and developing DH. I suspect that McLuhan’s notions about technology as an extension of human senses and about the plasticity of human consciousness – and the theological impulse behind them – have a lot to contribute to the discussion surrounding the value of DH. Marshall McLuhan, as a Catholic humanist who anticipated many essential features of digital culture, is a figure uniquely positioned to reveal how theology can apply to this emerging field. I will argue specifically that McLuhan’s incarnational principle, critiqued and developed by contemporary digital humanists, can reveal DH to be a fully embodied endeavor that resonates with the malleability of human cognition.
