What defines, distinguishes, and creates otherness are the boundaries between things. In the case of human persons, otherness comes from the boundaries between bodies. [Wendell Berry has a ton of awesome writing about this. Definitely worth looking into his stuff.]
If the boundaries between bodies is what creates our sense of the other, what we fill these boundaries with creates the kind of otherness we imagine and subsequently interact with; whether friend or foe, foreign or familiar.
For the sake of the story I’m attempting to unpack –
otherness becoming us-ness so we can live a new and radical kind of one-another-ness
– we must remember that otherness is created based on what we imagine to fill the spaces between our bodies. In other words, otherness is a construct. An important one that we rely on for interaction and survival, but a construct, creation, and imagined reality, nonetheless.
