R. Buckminster Fuller is regarded as one of the most important figures of the 20th century, renowned for his achievements as an inventor, designer, architect, philosopher, mathematician, and dogged individualist. Perhaps best remembered for the Geodesic Dome and the term "Spaceship Earth," his work and his writings have had a profound impact on modern life and thought.

Critical Path is Fuller's master work--the summing up of a lifetime's thought and concern--as urgent and relevant as it was upon its first publication in 1981. Critical Path details how humanity found itself in its current situation—at the limits of the planet's natural resources and facing political, economic, environmental, and ethical crises.

The crowning achievement of an extraordinary career, Critical Path offers the reader the excitement of understanding the essential dilemmas of our time and how responsible citizens can rise to meet this ultimate challenge to our future.
