As stated above in network example 1, when energy or matter moves across a system boundary, the system moves further from equilibrium and to that extent can be said to aggrade thermodynamically, the opposite of dissipation (boundary exit) and degradation (energy destruction). Aggradation is negentropic, although entropy is still generated and boundary-dissipated by interior aggrading processes. Environ theory appears to solve Schrodinger's What-is-Life? riddle (1944) of how antientropic development can proceed against the gradient of second-law degradation and dissipation. It shows a necessary condition for aggradation to be one single interior transaction within the interior system network—simple adjacent electromagnetic interaction! Given openness and sustained boundary input and output, there would appear to be no upper bound on this interior aggradation process. Thus, everything in nature that concerns differentiation and diversification of living and non-living structures and processes, and transactional interactions between these both within and across scales, can be seen as incrementally contributing to network aggradation—movement away from equilibrium. Recalling the observation above that solar photons come in small quanta that can only power processes at similarly small scales, and the fact that scales increase bottom-up through interactive coupling, network aggradation would appear to provide, perhaps, an electromagnetic-coupling answer to Schodinger's durable question, "What is life?" Unbounded energy- and matter-based linkage following on boundary openness would be an elegant basis indeed for life in its thermodynamic dimensions— simple and ubiquitous.
