ABSTRACT We are concerned with borders and their crucial importance in people's lives. Throughout we place emphasis on liberatory critique and knowledge and on the importance of the forces lineages exercise in the ways we live. How might we speak of whatever is bordered and allow that of which we speak its manifest differences? How are we able to engage differences and maintain our own differences? How might we, as philosophers, speak philosophically about what is beyond philosophy? Such speaking would (...) constitute an art, a philosophical art, that is guided by unspeakable differences. After developing the concepts of border, in-between, sensibility, and mutations of lineages, we turn to Gloria Anzaldúa's accounts of border awareness and her experiences of it. Through an engagement with her account of nepantla, we offer reflections on the force that “beyond” can have in the happenings of liberatory philosophies. In doing so, we emphasize her conceptions of border arte and her manner of bringing it to expression. In that process we find parts of Alejandro Vallega's work helpful in elaborating radical exteriority, fluid margins, and “ana-chronic” sensibilities. We are engaging a philosophical understanding that gives us bridges that provide thresholds beyond philosophy. (shrink)
