This is the written thesis component of a practice as research project which was also examined through a live performance and a portfolio of documentation of my performance art practice. It articulates the process of development of an endogenous research methodology of interaction between Emmanuel Levinas’s major opus on ethics, Totalité et Infini, and my practice in experimental performance art. It conceptualises the interaction as a dialogue – one which safeguards the integrity of both parts but invites contamination/contagion by one another. The methodology is one of my key contributions to the fields of Artistic Research and Performance Philosophy: conceived as transmissible, usable and adaptable by other artist-researchers, it is put at the service of advanced academic enquiry and artistic experimentation. It is consistent with the openness towards Otherness that Levinasian ethics projects upon performance art practices: the development of ethically empowered and ethically-empowering performance art is its major outcome, my second key delivery. When focusing on the place of Otherness within Levinasian ethics, and on how to approach Otherness in – and through – experimental performance art, I argue that the experimental nature of performance is necessary to ensure openness, porosity and integrity. I also show how the dialogue between Levinas and performance generates advancements in the scholarship on Levinas – my third key delivery. Applying the methodology to “spin-off” dialogues led to findings on performance purposes, as well as to a critical view of the institutional context of artistic research through performance – the fourth delivery. For me, the corpus of performance art experiments accompanying this written thesis component holds equivalent value to this text. It can only in part be reflected or referred to here. Among those experiments, a “final” live performance was specifically conceived to be the other part of my submission, and it has been presented almost simultaneously to the written thesis component.
