Differentiation by Evan Calder Williams between horror and terror that reflects both a representational turn (in terms of genre) and in real-life manifestations. Horror is repetitive, recyclable, unending, instructive.
Terror is about the threat to life, the knife behind you. Horror, conversely, is about the threat to understanding, of living to see the after-effects of suddenly realizing you were behind the knife all along. In this way, horror is apocalyptic. It confronts us with the symptoms – and with our complicity in reproducing them – and demands that we find new sets of instructions. – Evan Calder Willams, Combined and Uneven Apocalypse, pg. 226.
