Cadzao, Once upon a time I studied to be an architect, so I know a bit about Le Corbusiers' architecture and theory. I am not familiar with the author of the text that you are quoting from, but he seems to express a critisism of how this "completely rational basis" of urban planning and architecture, coupled with the inevitable centralisation of such "completely rational" decision-making processes, will inevitably result in an urban landscape that is imposed on its dwellers. It could therefore be considered "authoritarian", in the sense that the inhabitantas of Le Corbusiers' vision are objects of, not participants in, the "rational" decision making process.
