The orthodox concept of the Modern, as it was passed down from the 1920s to the post-war era, has been in a state of crisis for quite some time. This is particularly visible in the fields of urban planning, architecture, and design. Theorists and practitioners have either fiercely defended it as a crowning historical achievement to be upheld and further cultivated, or dismissively rejected it as a short-lived and outdated episode that needs to be replaced with something different and new.
