Concepts
- Critical path. The title of the book is a term used in project planning. To estimate the completion date of a project, a chart is drawn showing all of the necessary sub-tasks and their durations, placed in chronological order. The last task cannot begin until all of tasks on which it depends have been completed. These tasks depend, in turn, on other tasks. It is usually possible to draw numerous paths through the chart from beginning to end, but it is the longest path, called the critical path, that determines the time that the project will take to complete. The book refers frequently to the Apollo Project, which was planned using this method. Fuller's plan to reorganise the global economy in a sustainable way also has a critical path, which is identified in the book.
- Spaceship Earth. The Earth's material resources, like those of a spaceship, are finite. The book explains that early humans did not understand this, because the Earth seemed like a boundless flat surface. We now know that the Earth is a sphere, and this fact should inform all of our decisions.
- Personal integrity. Critical Path is part manifesto, part autobiography. Fuller admits in one place that this is "egostistical" (p. 378), but excuses this by saying that he wants to show not just his conclusions, but also the thought processes that led to them. He believes that every person must think for himself and take as little as possible on trust (p.xi).

Famous quotes containing the word concepts:
“During our twenties...we act toward the new adulthood the way sociologists tell us new waves of immigrants acted on becoming Americans: we adopt the host culture’s values in an exaggerated and rigid fashion until we can rethink them and make them our own. Our idea of what adults are and what we’re supposed to be is composed of outdated childhood concepts brought forward.”
—Roger Gould (20th century)
“Institutional psychiatry is a continuation of the Inquisition. All that has really changed is the vocabulary and the social style. The vocabulary conforms to the intellectual expectations of our age: it is a pseudo-medical jargon that parodies the concepts of science. The social style conforms to the political expectations of our age: it is a pseudo-liberal social movement that parodies the ideals of freedom and rationality.”
—Thomas Szasz (b. 1920)
“Science is a dynamic undertaking directed to lowering the degree of the empiricism involved in solving problems; or, if you prefer, science is a process of fabricating a web of interconnected concepts and conceptual schemes arising from experiments and observations and fruitful of further experiments and observations.”
—James Conant (1893–1978)
