The American philosopher Judith Butler is one of the preeminent contemporary thinkers on issues at the intersection of gender and identity. A professor at the University of California, Berkeley and at the European Graduate School, she’s perhaps best-known for her book Gender Trouble (1990), which argues that gender, sex and sexuality are continuous and highly mutable cultural performances, and not predetermined by human biology. This brisk and energetic video from the French filmmaker Géraldine Charpentier-Basille animates cutouts of diverse human forms to accompany an extract from a 2006 interview with Butler in which she cites Simone de Beauvoir’s The Second Sex (1949) as inspiration. Although brief, the piece is an excellent conversation-starter on the question of what ‘becoming’ might mean, both in the context of gender and more broadly in the pursuit of the ‘authentic’ self. It’s also a pleasing reminder of the many ways that ideas spread and transmute over time.
