The phrase “always already” is, in the main, attributed to the poststructuralist philosopher Jaques Derrida. It has, however, come to be a trope for the new materialists and it is in this usage that I modestly take it on. Specifically, my guiding sources are from the feminist technoscience scholars Donna Haraway and Karen Barad, both of whom make heavy use of the phrase to trouble the binaries abound in science and technology (subject-object, mind-matter, inside-outside, past-present, etc.).
