Book excerpt: Design Intervention: Toward a More Humane Architecture, first published in 1991, intends to demonstrate that interest in social issues is alive and well in architecture, that there is a small but effective cadre of dedicated professionals who continue to commit themselves to solving social problems, and that architecture is being applied to the alleviation of the social ills of our time. The editors and contributors in this book have all grappled with their own definitions of design innovation, and express in practical and useful ways their ideas for contributing to a better and less needy world through the architecture they describe. This book will be of interest to students of architecture.
