Living SystemsOffering a detailed analysis of each of the major aspects and characteristics encountered at all seven levels, Living Systems identifies multiple variables of each of 9 matter-energy and information-processing subsystems, the normal and pathological states of these variables, and practical indicators for measuring changes in them. It also specifies cross-level formal identities among the levels and describes the artifacts, machines, or technologies at each level. |
