" Alterity? —The concept of “otherness.” What I am is very much a function of what I am not. If the “other” is the Muslim world, then I am the Judeo-Christian world. If the other is from thousands of light-years away, I am simply human. Redefine alterity and you can erase boundaries. "

― Sylvain Neuvel , Sleeping Giants (Themis Files, #1)
