The Routledge Companion to Criticality in Art, Architecture, and Design presents an in-depth exploration of criticism and criticality in theory and practice across the disciplines of art, architecture, and design. Professional criticism is a vital part of understanding the cultural significance of designed objects and environments that we engage with on a daily basis, yet there is evidence to show that this practice is changing. This edited volume investigates how practitioners, researchers, educators, and professionals engage with, think about, and value the practice of critique. With contributions from a multi-disciplinary authorship from nine countries - the UK, USA, Australia, India, Netherlands, Switzerland, South Africa, Belgium, and Denmark - this companion provides a wide range of leading perspectives evaluating the landscape of criticality and how it is being shaped by technological and social advances. Illustrated with over 60 black and white images and structured into five sections, The Routledge Companion to Criticality in Art, Architecture, and Design is a comprehensive volume for researchers, educators, and students exploring the changing role of criticism through interdisciplinary perspectives.
