The totality of what exists and occurs, including both observable phenomena and the underlying structures that give rise to our experience of existence.

Reality is a fundamental concept that encompasses the complete state of things as they actually exist, as opposed to what might be imagined, theorized, or perceived. The nature of reality has been a central concern in philosophy, systems theory, and cybernetics, particularly regarding how systems interact with and model their environment.

From a systems perspective, reality can be understood through several key frameworks:

Constructivist View The constructivism approach, developed by thinkers like Heinz von Foerster and Ernst von Glasersfeld, suggests that our understanding of reality is actively constructed through observation and cognition. This connects to second-order cybernetics in recognizing that observers are part of the systems they observe.
Systems Ontology Reality emerges from the interactions of interconnected complex systems. These systems exist in multiple hierarchical organization, from quantum phenomena to social structures. Each level exhibits emergence that cannot be reduced to lower levels.
Information Processing Following Gregory Bateson's work, reality can be understood as patterns of information and difference that make a difference. This connects to both cybernetics and modern information theory.

Key aspects of reality relevant to systems thinking include:

Observer Dependence The observer suggests that reality cannot be entirely separated from the act of observation, linking to both quantum physics and epistemology.
Autopoiesis Living systems create their own reality through self-organization and maintenance of boundaries, as described by Maturana and Varela.
Complexity Reality exhibits non-linear causation, feedback loops, and emergent properties that challenge reductionist approaches.

Applications and Implications:

In system design, understanding reality's complex nature helps create more resilient and adaptive systems.
In cognitive science, it informs how systems create internal models of their environment.
In social systems, it helps explain how collective realities emerge from individual interactions.

Modern developments in quantum physics and complexity science have reinforced systemic views of reality as inherently interconnected and observer-dependent. This has led to new frameworks for understanding consciousness, emergence, and the nature of information in physical systems.

The concept of reality remains central to understanding how systems perceive, model, and interact with their environment, making it a foundational concept in systems theory and related fields.
