RT info:eu-repo/semantics/article T1 Heart from Darkness: Apocalypse Ron A1 Martin, James R. K1 Power, solidarity, appraisal, attitude, engagement, Critical Discourse Analysis AB Power implies resistance, no more dramatically perhaps than when whistle-blowers call the tune. In this paper I’ll look at one well known example of whistle-blowing from the Vietnam War—Ron Ridenhour’s exposé of the My Lai massacre in 1969. Ridenhour’s initial letter to the US Department of Defence and Congress contrasts in interesting ways with two additional recounts of the atrocity delivered later in his career. Appraisal theory, attitude and engagement analysis in particular, off ers an interesting window on how his rhetoric develops over time—as he wrestles with the twin dimensions of power and solidarity, initially as a recently discharged veteran of the war and later on in his career as an award winning investigative journalist. My choice of data refl ects my concern with balancing CDA’s usual focus on discourse in the service of power with analyses of discourse that unsettles power—a positive discourse perspective (PDA) on sites of social change.
