The first in a multi-volume work, Maintenance: Of Everything, Part One offers a comprehensive overview of the civilizational importance of maintenance. The book explores the insights that can be gleaned from the maintenance of sailboats, vehicles, and weapons, with absorbing detours into the evolution of precision in manufacturing, the enduring importance of manuals, sustainment in the military, and the never-ending battle against corrosion. Maintenance: Of Everything is a wide-ranging and provocative call to expand what we mean by “maintenance.” It invites us to understand not only the profound impact maintenance has on our daily lives but also why taking responsibility for maintaining something—whether a motorcycle, a monument, or our planet—can be a radical act.
