"To gain a general understanding of emergent phenomena, then, it's necessary to describe the emergence of a systems behavior from the non-additive interactions of its building blocks (particles, traders, etc,). The formal counterpart of the building block concept is required if the description is to encompass all complex systems. The generators discussed in the previous chapter provide that counterpart. Briefly said, emergence occurs when the generators for a generated system combine to yield objects having properties not obtained by summing properties of the individual generators."
