This article proposes the concept of ‘memory script’ to analyse how, in the aftermath of political violence, memory activists narrate their lives in a way that is practised, repetitive and performative. Through a self-reflective life history of Aluízio Palmar, a Brazilian human rights activist and former political prisoner who suffered intense torture under military rule, this approach seeks to elucidates the personal and political contours of somebody's decision to transform their experiences into a public narrative. A close reading of Palmar's various platforms of memory-sharing reveals the complex moral reckoning of an activist's own trauma.
