"Today, the notion of progress in a single line without goal or limit seems perhaps the most parochial notion of a very parochial century"

In this quote, Lewis Mumford is suggesting that the concept of progress as an endless, direct trajectory is a narrow-minded and out-of-date view of the world. He suggests that the concept of progress with no ultimate destination or boundaries is limited and short-sighted, belonging to a time and location that values blind pursuit of development and advancement above all else. Mumford suggests that a more holistic and inclusive view of progress is required, one that considers the complexities and diversity of the world we live in. In general, Mumford advises us to move beyond simplified concepts of progress and strive for a more nuanced and vibrant understanding of human development.
