Judith Butler (born 1956) is a philosopher at the University of California, Berkeley, whose work spans gender theory, ethics, political philosophy, and psychoanalysis. Their concept of performativity — that gender is not an expression of an inner truth but is constituted through repeated performances — has transformed how gender, identity, and subjectivity are understood across the humanities.

Core ideas

  • Performativity: in Gender Trouble (1990), Butler argued that gender is not the expression of a pre-existing identity but is produced through the repetition of culturally regulated acts — gestures, speech, bodily dispositions. There is no gender identity behind the expressions of gender; the identity is constituted by the expressions themselves. This does not mean gender is a free choice or a costume — the performances are compelled by social norms that precede and exceed any individual.
  • Grievability: in Frames of War (2009) and Precarious Life (2004), Butler asked which lives count as grievable — whose deaths register as losses. The unequal distribution of grievability structures who is recognized as human and who is treated as expendable. Lives that cannot be grieved cannot be fully lived, because they are not apprehended as lives in the first place.
  • Precarity: Butler distinguishes between precariousness (a shared condition of vulnerability that characterizes all living beings) and precarity (the politically induced condition in which certain populations are made disproportionately vulnerable to harm). Precarity is not natural but produced — through policy, infrastructure, and the selective withdrawal of support.
  • Constitutive exclusion: Butler’s work consistently examines how categories produce their outside — how the definition of the human, the normal, the intelligible depends on the exclusion of what is deemed non-human, abnormal, unintelligible. The excluded term is not simply absent but constitutive: the category depends on what it excludes.
