Book excerpt: The Companion to Public Space draws together an outstanding multidisciplinary collection of specially commissioned chapters that offer the state of the art in the intellectual discourse, scholarship, research, and principles of understanding in the construction of public space. Thematically, the volume crosses disciplinary boundaries and traverses territories to address the philosophical, political, legal, planning, design, and management issues in the social construction of public space. The Companion uniquely assembles important voices from diverse fields of philosophy, political science, geography, anthropology, sociology, urban design and planning, architecture, art, and many more, under one cover. It addresses the complete ecology of the topic to expose the interrelated issues, challenges, and opportunities of public space in the twenty-first century. The book is primarily intended for scholars and graduate students for whom it will provide an invaluable and up-to-date guide to current thinking across the range of disciplines that converge in the study of public space. The Companion will also be of use to practitioners and public officials who deal with the planning, design, and management of public spaces.
