Fundamental behavioral properties, part I: extending the theory of centers for pattern language 3.0

Christopher Alexander explored the hidden quality in a town or a building and defined the concepts of wholeness and centers in his book, The Nature of Order. He said that the whole becomes lively when centers intensify each other and proposed fifteen fundamental properties that describe how centers intensify each other. These properties are geometrical so it is still unknown whether it will work for things that are hard to perceive only by shapes or spatial characteristics, such as human actions or society. In this paper, we present the fundamental behavioral properties of lively human actions, found through the investigation of human activity Pattern Languages on the basis of Alexander's theory of wholeness and center. Out of the 24 properties we found, we introduce 6 properties in this paper: 1. BOOTSTRAP, 2. SOURCE, 3. SPREADING, 4. ATTRACTION, 5. INVOLVING, and 6. TOGETHERNESS.
