The Aesthetics of Decay, Dylan Trigg confronts the remnants from the fallout of post-industrialism and postmodernism. Through a considered analysis of memory, place, and nostalgia, Trigg argues that the decline of reason enables a critique of progress to emerge. In this ambitious work, Trigg aims to reassess the direction of progress by situating it in a spatial context. In doing so, he applies his critique of rationality to modern ruins. The derelict factory, abandoned asylum, and urban alleyway all become allies in Trigg’s attack on a fixed image of temporality and progress. The Aesthetics of Decay offers a model of post-rational aesthetics in which spatial order is challenged by an affirmative ethics of ruin.
