Authentic Fake: Authenticity And Authentication., Suyun Son

Electronic Theses and Dissertations

My thesis exhibition questions the modern sanctification of authenticity. No longer believing in objective truths, the postmodern society seeks epistemic grounding on being true to oneself. The categories of authentic-or-fake replaced the binary of true-or-false. But authenticity is a trojan horse for authentication. As a Korean American artist, I'm encouraged to express my “authentic” Korean identity. This encouragement can also imply my works will receive recognition as authentic and meaningful only when they embody Korean cultural expression. Authenticity becomes a performance for the sake of authentication. Ironically, authenticity turns into an act of conformity/confirmation. Authenticity demands you stay true to …
