Unlike fast knowledge generated in universities, think-tanks, and corporations, slow knowledge occurs incrementally through the process of community learning motivated more by affection than by idle curiosity, greed, or ambition. The worldview inherent in slow knowledge rests on these beliefs: • Wisdom, not cleverness, is the proper aim of all true learning • The velocity of knowledge can be inversely related to the acquisition of wisdom • The careless application of knowledge can destroy the conditions that permit knowledge of any kind to flourish (a nuclear war, for example, made possible by the study of physics, would be detrimental to the further study of physics) • What ails us has less to do with the lack of knowledge but with too much irrelevant knowledge and the difficulty of assimilation, retrieval, and application as well as the lack of compassion and good judgment • The rising volume of knowledge cannot compensate for a rising volume of errors caused by malfeasance and stupidity generated in large part by inappropriate knowledge • The good character of knowledge creators is not irrelevant to the truth they intend to advance and its wider effects • Human ignorance is not an entirely solvable problem; it is, rather, an inescapable part of the human condition.

The total paved area in the lower 48 states is equivalent to a land area larger than Kentucky. As a result, water moves more quickly across our landscapes than it once did, so that flooding, particularly downstream from urban areas, is more common and more severe than ever.
