Abstract
This study tris to connect 'The Genealogy of Morality' by Nietzsche with Koolhaas's arguments in his book, 'Delirious New York'. It is to apply Nietzschean terms, ideas, and the way of genealogic approach into the architectural origin of Koolhaas, which only can be examined through his complicated and surreal writings. The body of this paper has distinguished but interrelated two parts. The first part deals with Koolhaas's critics on the modern masters and contemporary architecture by reconstructing his arguments in the structural frame of 'The genealogy of Morality'. The paper argues that the modern masters are 'the architects of ressentiment', that passive architectural professionals are 'the businessmen of guilt', and that contemporary architects are 'the ascetic idealist'. The second part examines Koolhaas's Manhattanism in the perspective of Nietzschean trinity, which are named as 'Architectural Symptomology', 'Quantitative Typology', and 'Architectural Genealogy'. The study conclude that Koolhaas is a 'Heroic optimist', who ultimately affirms our life itself, explores the forces below its symptoms, and creates the unforeseen future by reconstructing the relations of the forces.
