Among many other things, Mark Fisher was one of the most gifted prose writers of his generation. His early death deprived us of an unknowable number of unsettling new ideas. Flatline Constructs, originally Fisher's doctoral thesis at Warwick University, is a precious gift from the other world, where he now resides. ~ Graham Harman, American philosopher and Distinguished Professor of Philosophy at the Southern California Institute of Architecture in Los Angeles

Flatline Constructs is Mark Fisher’s piercing précis of the metaphysics of cybernetics, whose herald is Spinoza. Fisher’s ‘gothic flatline’ annuls the difference between fiction and reality, obliterating representation with circuitry, the mirror with the screen, and law with code. If Flatline Constructs’ principal tropes — machinic animism and agency without subjectivity — have become theoretical commonplaces in the 25 years since its composition, its publication now retrospectively illuminates the political debility of a cybernetic realism that snuffs out every alternative to the present. Flatline Constructs diagnoses the paralyzing predicament which Fisher’s subsequent work would struggle to overcome. ~ Ray Brassier, British philosopher and author of Nihil Unbound: Enlightenment and Extinction
