This book is inspirational for those who believe in modern architecture. The ideas are still as potent as ever. This book reflects the optimism of those early 20th century architects who worshipped new technology, who had a fervent desire to do every "modern" using industrial materials, who denounced old materials like stone and wood, who preached the benefits of a social architecture for the masses. For almost a century, this book has also influenced every great architects in the 20th century.
Having said all that, this book needs to be read with the reminder that not everything it preaches is "correct" and the many manifestations of modern architecture is darn right "de-humanizing" and "souless". This book is best contrasted by the work of Frank Lloyd Wright and many contemporary architects who emphasize the importance of a sense of "living" space in architecture.
