Definitions for "Phase space"
The state space of a system, a mathematical abstract space used to visualize the evolution of a dynamic system (Nicolis & Prigogine, 1989). Phase space for the ego is defined here as a 2-dimensional chart showing relationships between consciousness, the personal unconscious, and the collective unconscious over time.
In this book, another name for state space. In the scientific literature, ``phase space'' is used to denote the space of motion in a dynamical system that moves in continuous time, while state space is often used for discrete time systems.
An abstract space used to represent the behavior of a system. Its dimensions are the variables of the system. Thus a point in the phase space defines a potential state of the system. The points actually achieved by a system depend on its iterative function and initial condition (starting point).
