Systems Theory
Overview
Systems theory provides a transdisciplinary framework for understanding complex phenomena through the lens of systems and their interactions. This theoretical framework is fundamental to understanding cognitive systems, emergent behavior, and complex biological systems.
Core Concepts
1. System Properties
- Wholeness: Systems must be understood as wholes rather than collections of parts
- Hierarchy: Systems exist within systems (subsystems and supersystems)
- Emergence: System-level properties emerge from component interactions
- Self-organization: Systems can spontaneously develop order
- Feedback: Systems regulate through feedback loops
2. System Dynamics
- Homeostasis: System stability through self-regulation
- Adaptation: System changes in response to environment
- Evolution: Long-term system development
- Phase Transitions: Qualitative changes in system behavior
- Attractors: Stable states toward which systems tend
