Bertalanffy’s General Systems Theory (GST)

Ludwig von Bertalanffy developed GST in the mid-20th century as a framework to understand complex systems in biology, psychology, and social sciences. Key principles include:

1. Holism: Systems should be viewed as wholes, not just as collections of parts.

2. Open Systems: Unlike closed systems, open systems interact with their environment through input and output of energy, matter, and information.

3. Hierarchy: Systems are nested within other systems (also called "systems within systems").

4. Equifinality: A system can reach the same end state from different initial conditions and through different paths.

5. Homeostasis & Feedback: Systems maintain stability through feedback loops that regulate their behavior.

6. Non-linearity: System behavior often includes non-linear relationships between components.

7. Interdependence: All parts of a system are interrelated and a change in one part affects the whole.

Bertalanffy’s aim was to offer a scientific language for dealing with complexity, offering alternatives to reductionism and mechanistic views.
