Dynamic quality can be poetically described as the force of change in the universe; however, when an aspect of Quality becomes repeated, it becomes static. Pirsig defines 'static quality' patterns as everything which can be defined. Everything found in a dictionary, for instance, is a static quality pattern. Pirsig then divides static quality into inorganic, biological, social, and intellectual patterns, in ascending order of morality (based on evolutionary order). These static forms, if they have enough 'high' or 'low' quality, are given names and are interchanged with other "sentient beings", building the base of knowledge for a culture.
