 According to Bach, Haslanger’s strategy to resolve these problems appeals to ‘social objectivism’. First, we define women “according to a suitably abstract relational property” (Bach 2012, 236), which avoids the commonality problems. Second, Haslanger employs “an ontologically thin notion of ‘objectivity’” (Bach 2012, 236) that answers the representation problem.

He thus proposes that women make up a natural kind with a historical essence:
