guest who received hospitality, as opposed to the xeinodokos or "host", who welcomed strangers and provided them with hospitality. It is from this perspective, that of the immigrant, the stranger within a society, as opposed to that of society or the xeinodokos viewing the outsider, that Wodiczko employs the term xenology: "Xenology is the art of refusal to be fused, an art of delimitization, deidentification, and disintegration" ("Xenology: Immigrant Instruments", exhibition statement distributed at the Galerie Lelong, New York, 1996). Wodiczko calls xenology "a new, nomadic, and yet undeveloped form of understanding and expression". Like the Eleatic Stranger (Xenos) in Plato's The Sophist, the vehicle of Wodiczko's xenology is a "nomadic Sophist", a "practitioner of democracy" who "recreate[s] an agora or forum each time he or she wishes to speak or listen." Recent work While working on Porte-parole in Europe, Wodiczko received an invitation from the filmmaker Andrzej Wajda to participate in an urban festival in Kraków using for the first time powerful Barco NV video projectors. Working with the Women's Center, he merged for the first time the testimonial work that had evolved from his work with instruments with the visual impact of his well-known large-scale public projections. Testimony of domestic abuse spoken from the City Hall Tower created shockwaves in an overwhelmingly Catholic culture of denial. In this way, Wodiczko continued in his testimonial video projections to respond to the needs of urban society's marginal citizens who frequently survive outside the usual boundaries of juridical and social resources. In 2001, he merged the means of his instruments with the purpose of the projections in his Tijuana Projection executed for InSite 2000. In this public intervention, women working in the "maquiladora" industry of Tijuana, Mexico wore media technology designed to project their faces onto El Centro Cultural as they spoke emotionally of incest, police abuse, and work place discrimination in real time. As participants, their parrhesiastic speech was courageously offered at great risk to themselves for the purpose of moral and political change. Through the video projections, Wodiczko continues to develop the potential for aesthetic practice to effect social change as part of a wider discourse on agonistic pluralism prompted by such influences as Chantal Mouffe and Ludwig Wittgenstein. The role of art in understanding and confronting conflict becomes an increasingly significant aspect of both Wodiczko's aesthetic and pedagogical practices. This is true in his continued work with immigrants
