In this volume, the numerous excerpts, preliminary notes, accompanying drawings, and photographs that Le Corbusier produced in connection with his lectures are presented and contextualized by one of the leading experts on the great architect. In them we see modernism at work. Always a great rhetorician and a master at staging his own persona, Le Corbusier takes the arguments and strategies, seminal ideas and most convincing highlights and fuses them into an architectural conception that every advanced architectural position and practice must still come to terms with today.
