The French systemist B. WALLISER proposed the following properties as characteristic of systems:
Diacronic properties: “Set of the relations among the various characteristics of the system at succesive moments” (1977, p.73).
Synchronic properties: “Set of the relations among the various characteristics of the system at the same moment” (p.73).
In a system both synchronic and diachronic properties must be permanently non-contradictory.
Emergent property: “Any new property of the system that is not a property of any of its subsystems or elements and is essentially due to the characteristics of the net of their interrelations” (p.47).
Immergent property: “Property of some subsystem that cannot anymore be found at the level of the system” (p.47).
Both types of properties can be synthetized as follows: “A system is at the same time, more and less than the sum of its parts”.
