Perceiving how things are is a mode of exploring how things appear. How they appear is, however, an aspect of how they are. To explore appearance is thus to explore the environment, the world. To discover how things are, from how they appear, is to discover an order or pattern in their appearance. The process of perceiving, of finding out how things are, is a process of meeting the world; it is an activity of skillful exploration.
